This case report discusses a diagnosis of uterine torsion in an 84-year-old woman who presented with five days of right lower quadrant abdominal pain, nausea, vomiting, constipation, and poor intake. Computed tomography (CT) imaging demonstrated a whorled configuration at the junction of the cervix and lower uterine segment, with the left gonadal vein crossing midline, and two previously known right leiomyomas now appearing on the left. These findings were consistent with the diagnosis of uterine torsion. She then underwent an urgent exploratory laparotomy, and the uterus was found to be dextroverted 270 degrees, with dark mottled purple tissue and engorged vessels. A supracervical hysterectomy and bilateral salpingo-oopherectomy were performed. Final pathology demonstrated extensive necrosis. This case reviews the classic presentation and imaging findings for the rare diagnosis of uterine torsion and options for management of both non-gravid and gravid patients.

Background: Intervertebral disc herniation, defined as the protrusion or extrusion of the disc mass outside the disc space, is common and easy to diagnose on conventional Magnetic Resonance imaging (MRI) or Computed Tomography (CT) scans. However, the sequestrated disc fragments are challenging to detect, and intervertebral disc mass displacement into the dural sac, which can lead to serious neurological problems such as Cauda equina syndrome (CES). The sequestrated disc fragments do not have specific clinical or radiological characteristics that can differentiate an atypical disc mass from a tumor, making the diagnosis difficult preoperatively. Herein, we describe the use of Sampling Perfection with Application Optimized Contrast using different flip angle Evolution in Magnetic Resonance Imaging (3D SPACE MRI) in the diagnosis of the intervertebral disc fragment that mimicked a tumor.

Case presentation: In this study, we report two cases of sequestered lumbar disc herniation. The first case was a 37-year-old patient with a 2-year history of intermittent left lower limb pain that aggravates with exercise and is relieved at rest, while the second case was a 42-year-old patient with a history of 40 days of numbness and pain in the left lower limb.

Conclusion: 3D SPACE MRI is a beneficial diagnostic imaging tool for discriminating between disc mass that mimics a tumor and a tumor before surgery. If the disc fragment mimicking a tumor can be identified before the operation, open surgical treatment won't be necessary for all patients.

Rectal cancer Is a Common malignant pathology; its usual spread in volves the liver and lungs. The occurrence of renal metastases is exceptional. CT scanning aims to evaluate extension and may incidentally reveal a renal mass, which can be better characterized through MRI and ultrasound. We describe a case of a solitary renal metastasis from rectal cancer and underscore the significant role of imaging in positively diagnosing this uncommon pathology.

Multiple myeloma is a plasma cell neoplasm, which may present as a solitary plasmacytoma and, uncommonly, as an extramedullary plasmacytoma. Intracranial plasmacytomas may manifest in central nervous system involvement as cranial nerve palsies. Cranial nerve six palsy is the most common in cases of malignancy. However, isolated abducens palsy presenting as multiple myeloma recurrence is very uncommon. Here, we detail two cases in which intracranial plasmacytoma lesions were present within the region of the Dorello canal, resulting in acute isolated unilateral diplopia from disease recurrence in the absence of systemic marrow involvement.

Background: Traumatic intracranial ICA dissections are not commonly seen in children. Dissection resulting in perfusion deficit warrants intervention. Here we encountered a patient who experienced traumatic ICA dissection, treated by endovascular stenting.

Methods: A 10-year-old female presented with aphasia and right sided weakness following trauma. Imaging showed deficit in the left MCA territory without core. Further imaging showed dissection of the left supraclinoid ICA, confirmed by digital subtraction angiography.

Results: A Neuroform Atlas stent was placed without complication. All dysarthria and weakness had resolved on follow-up 5 months post-stenting.

Conclusions: Acute stroke symptoms in children can result in lasting deficits if not treated quickly. Medical management is regarded to be first line, depending on presentation. Endovascular stenting may provide a promising means to treat pediatric ICA dissections involving perfusion deficits and mitigate permanent ischemic changes.

Ewing sarcoma (ES) was first reported by Ewing in 1921. It is the second largest malignant bone tumor in children and adolescents, typically occurring in the bones of trunk or limbs . Extraskeletal Ewing sarcoma (EES) was first reported by Tefft et al. in 1969 and is extremely rare, accounting for less than 1% of all sarcomas. It can occur in any part of soft tissue, mostly in the trunk and lower limbs, and rarely in the pleura. We report a 22-year-old case of extraosseous Ewing sarcoma of pleural origin discovered and pathologically confirmed by physical examination. We report its CT manifestations and pathological results, and review the literature to summarize and analyze the clinical and imaging characteristics of extraosseous Ewing sarcoma, in order to improve our understanding of the disease.
