Re-expansion pulmonary edema occurs when the lung re-expands after an extended duration of collapse. It is rare with the reported incidence between 0% and 1%. We present a case of a 51-year male who presented with breathlessness, cough and right-sided chest pain. Chest radiograph showed right-sided pneumothorax. After 2 hours of chest tube insertion, the patient developed tachypnea and severe hypoxemia. HRCT chest revealed consolidation, ground glass opacity and smooth interlobular septal thickening in the right lung as well as a small patch of ground glass opacity in the contralateral lung. The serial radiograph showed resolution of consolidation and ground glass opacities.

Introduction:MRI is highly accurate in identifying vertebral anomalies by detecting even the smallest changes in water and fat components, making it the preferred method for assessing infectious lesions in the vertebral column. Clinical observations and different imaging properties can help with early diagnosis and treatment. Vertebral endplate destruction, changes in the signal intensity of intervertebral disc and bone marrow, and involvement of the soft tissues surrounding the vertebrae are typical MRI findings of infectious vertebral lesions.Methods:To determine the diagnostic accuracy of MRI in patients suspected of having infective vertebral lesions, a cross-sectional study was conducted involving 52 individuals. The study compared the validity of MRI diagnosis with the diagnosis obtained through CT-guided fine needle aspiration cytology for infective vertebral lesions.Results:By comparing the MRI diagnoses with those of fine needle aspiration cytological diagnosis of vertebral lesions, the sensitivity, specificity, positive and negative predictive values (PPVs and NPVs), and ultimately diagnostic accuracy of MRI, were computed. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MRI diagnosis for infective vertebral lesions were 95.6%, 71.4%,95.6%, and 71.4%, respectively and 92.3% of diagnoses were made correctly overall.Conclusions:The finding of this study suggested that MRI should be considered to be the imaging modality of choice for patients with suspected infective vertebral lesions.

Childhood cerebral hemiatrophy is a rare clinical condition. Its causes are numerous, but they can be divided into two categories: congenital and acquired. The congenital type develops intrauterine, whereas the acquired type develops early in life, usually before the age of two. Cerebral hemiatrophy syndromes are characterized by a wide range of neurological symptoms. Childhood epilepsy, mental retardation, and neuropsychiatric disorders are common, whereas movement disorders such as highly asymmetric parkinsonism or hemidystonia, as well as neuropsychiatric problems, have been reported in adults. Here we present a 22-year-old patient who presented with refractory seizure. Imaging findings showed hemiatrophy of the right cerebral hemisphere with left cerebellar atrophy.

A 33 years male presented with obstructive jaundice and was diagnosed as chronic cholecystitis with choledochocystolithiasis. The gastroenterology team performed ERCP with sphincterotomy to retrieve stone in common bile duct but failed. Open cholecystectomy with common bile duct exploration was done after few days. T-tube was placed in common bile duct. In the 8th post operative day, tube manipulation was done due to reduced drain output and pain abdomen. We performed T-tube cholangiogram on 12th postoperative day which showed duodenal migration of T tube. The displaced T tube was retrieved using a simple technique.

Introduction: Among various modalities used in the evaluation of chronic otitis media, HRCT of the temporal bone is the most reliable and valuable imaging modality as it provides excellent anatomic information. It can display minute anatomical and pathological details by providing a direct visual window into the temporal bone. Methods: This is a prospective cross-sectional study done at the department of Radiodiagnosis and imaging of Birat Medical College, Teaching hospital over 1 year with a total of 50 patients enrolled in the study. The findings were compared with the post-operative findings and data were entered. HRCT was done on 64 slices of multidetector CT scan. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of various parameters were calculated. Results: Out of 50 patients were enrolled in this study. Among them 52%(26) were females and 48%(24) were males. HRCT showed 100% sensitivity for the lateral semicircular canal and sigmoid plate erosion. The sensitivity and specificity of cholesteatoma were 79.06% and 42.85% respectively. It also offered a sensitivity of 75% and 95% for the erosion of the facial nerve canal and tegmen tympani respectively Conclusions: High-resolution computed tomography is a reliable diagnostic tool for the pre-operative evaluation of chronic otitis media. It helps the operating surgeon to evaluate the anatomical extent of the disease process and aids in the surgical approach that helps prevent probable complications during surgery

Introduction: Modern advances in radiology, imaging, and novel surgical methods have greatly aided doctors in making both surgical and non-surgical decisions. During surgery, anatomical variances are frequently encountered by surgeons, making operation complex and occasionally challenging. The purpose of our study was to evaluate the hepatic artery and its variants, including the length and diameter of the right and left hepatic arteries. This information is vital for patients undergoing major hepatic surgeries and hepatic transplantation Methods: A total of 120 patients who underwent contrast-enhanced Triphasic CT of the abdomen were evaluated with the consent of the ethics committee at Chitwan medical college. Study subjects were selected on a random basis, who had no previous abdominal or hepatic surgeries, and without the known hepatic disease. Results: Out of 120 participants, 63 (52.5%) were male and the rest 57(47.5 %) were females. Normal anatomy was observed in 104 cases (86.7%) and the rest of the 16 cases showed an anomalous hepatic arterial pattern, which consisted of Michel’s type III in 6 cases (5%), Type IV in 1 case (0.8%) and Type X in 3 cases (2.5%); and 5 cases (4.2%). did not fall under Michel’s Classification. Supply to segment IV of the liver was observed from Left hepatic artery in 97 cases (80.8%) and from the right hepatic artery in 23 cases (19.2%). Conclusions: Many hepatic arterial variants which did not fall under Michel’s classification were observed in our population.

Introduction: The coccyx, a triangular bone forming the last part of the vertebral column, acts as the weight-bearing structure when a person is seated, and is the site of insertion of the pelvic floor tendons and numerous ligaments attached to it. The main objective of this study was to investigate the morphology and morphometry of the coccyx on lumbar spine MRI images in asymptomatic individuals among Nepalese adults. Methods: This study was conducted retrospectively on the lumbar spine images of 190 adult population without a history of trauma in the coccyx region, from April to September 2019. The coccygeal vertebrae count, the number of bone segments, and intercoccygeal and joint fusions were determined from the sagittal plane images. In addition, the length and angles were also measured. Results: One hundred and ninety patients, with a mean age of 43.91 years, were enrolled in the study. Among the 4 types of coccyx; the most common type was type II (46.3%), followed by type I (40.5%). The coccyx was formed from 4 vertebral segments in 21.1% (n=41) individuals, 3 vertebral segments in 45.3% (n=86) individuals, 2 vertebral segments in 31.1% (n=59) individuals and 1 vertebral segment in 2.1% (n=4) individuals. Conclusions: In our study, type II coccyxes predominated. The prevalence of sacrococcygeal and intercoccygeal fusion, as well as the number of coccygeal vertebrae, were similar in the Nepalese population and the Western population.

Testicular seminoma needs to be considered as a differential diagnosis for intra-abdominal mass in the male patient if there is a history of undescended testis. The risk of developing seminoma in an undescended testis is about 4-7.5 times greater than in a normally located testis.The risk of seminoma in undescended testis is increased even after orchidopexy.The identification of the draining gonadal vein can play a key role in the diagnosis of the testicular tumor in undescended intra-abdominally located testis.

Introduction: The main aim of this study was to determine the mean value of liver stiffness in healthy adults using S-Shear wave elastography and compare liver stiffness with gender, age and BMI. Methods: A hospital-based cross-sectional study was carried out in the Department of Radiology, BPKIHS over 6 months after taking ethical approval from the institutional review committee. Ninety-six adults referred for ultrasonography of the abdomen for various indications were included in the study Results: Mean shear wave velocity of the healthy liver in the study subjects was 1.267±0.151m/s.The corresponding mean value of liver stiffness was 4.91±1.15 kPa. The mean liver stiffness was higher in males compared to females (5.283±1.08 kPa vs. 4.689±1.13 kPa) which were statistically significant (p=0.0013). Mean liver stiffness was highest in the age group of 70-79 years (6.7±0.80 kPa) compared to other age groups. There were significant differences between the mean liver stiffness values among different age groups (p=0.01). Patients in the obese class I category showed higher mean liver stiffness value (5.54±0.42 kPa) than other BMI categories. However, mean liver stiffness values showed no significant difference among different BMI groups (p=0.322). Conclusions: Liver stiffness values measured using S-Shear wave elastography in healthy adults ranged between 2.4 kPA to 7.4 kPa.There were significant differences in mean liver stiffness values between men and women and among different age groups. However, no significant difference was found among different BMI categories.

Introduction: Magnetic resonance imaging is a noninvasive diagnostic modality and provides clinically relevant information to orthopaedic surgeons by detecting and characterizing injuries of cruciate ligaments and meniscus of the knee. MRI is routinely used before arthroscopic examination and surgery. Arthroscopy is considered the reference standard for the diagnosis of injuries of cruciate ligaments and meniscus of the knee and hence the efficacy of MRI needs to be compared with arthroscopic findings. Methods: This was a retrospective observational study at Bheri hospital, Nepalgunj. A total of 114 Patients who were investigated with MRI and managed with arthroscopic procedures for a knee injury, between June 2017 to February 2022, were included in the study.Data analysis was done for determining true positive, true negative, false positive and false negative as per MRI and arthroscopic findings.Sensitivity, specificity, positive predictive value and negative predictive value were calculated based on specific equations. Results: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI for ACL were 89.65%, 96.42%, 96.29%, 90% & 92.98%, PCL was 96.42%, 100%, 100%, 97.72% & 99.12%, the medial meniscus was 88.46%, 88.70%, 86.79%, 90.10% & 88.59% and lateral meniscus was 84.61%, 94.31%, 81.48%, 95.40% & 92.10% respectively. Conclusions: MRI is an excellent noninvasive modality for imaging the knee and it yields high accuracy in diagnosing injuries of cruciate ligaments and meniscus.

A total of 114 Patients who were investigated with MRI and managed with arthroscopic procedures for a knee injury, between June 2017 to February 2022, were included in the study.Data analysis was done for determining true positive, true negative, false positive and false negative as per MRI and arthroscopic findings.Sensitivity, specificity, positive predictive value and negative predictive value were calculated based on specific equations.\u0000Results: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI for ACL were 89.65%, 96.42%, 96.29%, 90% & 92.98%, PCL was 96.42%, 100%, 100%, 97.72% & 99.12%, the medial meniscus was 88.46%, 88.70%, 86.79%, 90.10% & 88.59% and lateral meniscus was 84.61%, 94.31%, 81.48%, 95.40% & 92.10% respectively.\u0000Conclusions: MRI is an excellent noninvasive modality for imaging the knee and it yields high accuracy in diagnosing injuries of cruciate ligaments and meniscus.","PeriodicalId":178516,"journal":{"name":"Nepalese Journal of Radiology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122036070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
