Bizarre parosteal osteochondromatous proliferation (BPOP), or Nora’s lesion, is a rare benign surface bone lesion typically arising in the hands and feet. We report an unusual case involving the temporal bone in a 63-year-old woman, presenting with progressive external auditory canal obstruction and hearing-related symptoms. Imaging revealed a well-circumscribed osseous mass without corticomedullary continuity, and surgical excision with canaloplasty led to complete symptom resolution. This case expands the recognized anatomical spectrum of Bizarre parosteal osteochondromatous proliferation (BPOP) and underscores the importance of including it in the differential diagnosis of surface bone lesions in the craniofacial region, where even benign processes may result in significant functional impairment due to local anatomy.

Right ventricular outflow tract (RVOT) aneurysms are rare, often linked to congenital defects or surgery, and their incidental detection during acute pericarditis is unreported. This case highlights the diagnostic role of imaging in atypical presentations. A 32-year-old male presented with a 2-week history of sharp, pleuritic chest pain worsened by inspiration and coughing, partially relieved by nonsteroidal anti-inflammatory drugs (NSAIDs). He had a 10 pack-year smoking history but no prior cardiac disease. Physical examination was unremarkable. Laboratory tests showed mildly elevated C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Electrocardiography (ECG) was normal, but transthoracic echocardiography revealed a left ventricular ejection fraction (LVEF) of 40%, right ventricular enlargement, and moderate pericardial effusion. Multidetector computed tomography (MDCT) with pulmonary thromboembolism (PTE) protocol excluded PTE but incidentally identified RVOT aneurysm. Conservative management with aspirin and colchicine led to symptom resolution; at 6-month follow-up, the patient was asymptomatic with stable imaging. This incidental finding underscores MDCT’s utility in detecting coexisting structural anomalies in patients presenting with pericarditis. Conservative management is appropriate for asymptomatic cases without obstruction.

Neonatal duodenal perforation is an extremely rare but life-threatening surgical emergency. Reported etiologies include prematurity, necrotizing enterocolitis, distal obstruction, trauma, and sepsis; however, in rare instances, no identifiable cause is found and the condition is described as spontaneous. Early diagnosis relies heavily on radiologic imaging, particularly plain abdominal radiographs demonstrating pneumoperitoneum. We report a 2-day-old full-term female neonate who presented with progressive abdominal distension, nonbilious vomiting, and low-grade fever of one day duration. Laboratory evaluation showed leukocytosis with a high absolute neutrophil count and mildly elevated C-reactive protein; blood culture grew Klebsiella pneumoniae, for which appropriate antibiotic therapy was initiated. Supine abdominal radiography revealed massive pneumoperitoneum with classic radiologic signs, including the football sign and Rigler’s (double-wall) sign, consistent with gastrointestinal perforation. Exploratory laparotomy identified a solitary perforation on the anterior wall of the first part of the duodenum, with no evidence of distal obstruction, necrotizing enterocolitis, ischemia, or traumatic injury. The perforation was repaired by primary closure reinforced with a pedicled omental patch. Despite the presence of bacteremia, no intraoperative findings supported sepsis-related bowel necrosis, and the perforation was therefore classified as spontaneous. The neonate had an uneventful postoperative recovery. Although exceedingly rare, neonatal duodenal perforation carries significant morbidity and mortality. Prompt radiologic recognition of pneumoperitoneum and early surgical intervention are critical for favorable outcomes. This case highlights the diagnostic value of imaging and underscores the importance of carefully excluding infectious and secondary causes before labeling a duodenal perforation as spontaneous.

Disorders related to the falciform ligament are extremely rare. We present a case of a 56-year-old woman diagnosed with fatty-falciform ligament appendage torsion (F-FLAT). F-FLAT was detected on ultrasound and confirmed by computed tomography. The patient recovered well without further treatment beyond conservative measures. F- FLAT is usually self-limiting. Precise identification on ultrasound and computed tomography is crucial to avoid unnecessary surgical procedures.

Neurofibromatosis type 1 (NF1) is a clinical diagnosis supported by characteristic radiological multisystem manifestations. NF1 commonly presents with cutaneous, musculoskeletal, and neurological findings, while abdominopelvic involvement is less frequent. We present the case of a 7-year-old girl clinically and radiologically diagnosed with NF1 who was incidentally found to have a hepatic lesion. Further investigations confirmed a hepatic plexiform neurofibroma, a rare manifestation of NF1 with few reported cases worldwide. This report describes the patient’s neurological findings, as well as the sonographic, cross-sectional, and magnetic resonance imaging features of hepatic plexiform neurofibroma.

Septic involvement of the temporomandibular joint (TMJ) resulting in dislocation is an exceptionally rare entity and is most often associated with contiguous spread from deep cervicofacial infections. Early recognition and coordinated multidisciplinary management are essential to avoid severe functional and infectious complications. We describe the case of a 48-year-old woman with a background of chronic otitis media who presented with progressive left-sided facial swelling, trismus, and local signs of inflammation. Laboratory investigations demonstrated marked inflammatory response. Contrast-enhanced computed tomography of the head and neck revealed a left parapharyngeal abscess with extension to the masticator space, complicated by dislocation of the left TMJ. The patient was treated with surgical drainage combined with broad-spectrum intravenous antibiotic therapy. Clinical outcome was favorable, with resolution of the infectious process and gradual recovery of mandibular mobility. Although rare, TMJ dislocation secondary to deep cervicofacial infection should be considered in patients presenting with facial swelling and trismus, particularly when imaging demonstrates deep neck space abscesses. Prompt imaging assessment and multidisciplinary care play a pivotal role in achieving optimal outcomes.

A rudimentary horn is a type of congenital uterine anomaly associated with a unicornuate uterus. Rudimentary horn pregnancies (RHPs) are extremely rare and the majority of cases result in second trimester rupture necessitating emergent laparotomy with associated high maternal morbidity and delivery of a previable fetus. We report the case of a 33-year-old G5P0131 female who presented at 15 weeks and 4 days gestational age with pelvic and back pain and imaging favoring an abdominal pregnancy. The patient underwent an exploratory laparotomy with left salpingectomy and excision of an unruptured extrauterine pregnancy that was confirmed to be an RHP on pathologic examination. Postsurgery review of the imaging demonstrated several features consistent with the diagnosis of an RHP that were not initially identified. Furthermore, the patient’s medical and surgical histories were notable for several risk factors associated with congenital uterine anomalies that should have heightened the clinical suspicion for an RHP. This case emphasizes how increased familiarity with the risk factors and imaging findings associated with rudimentary horns and RHPs may lead to an earlier and more accurate diagnosis, more timely and appropriate treatment, and ultimately a reduction in maternal and fetal morbidity and mortality.

Prostate cancer is a common malignancy in men, typically metastasizing to bones, lymph nodes, and visceral organs. Epididymal metastasis, however, is extremely rare, with a reported prevalence of less than 4% and usually identified incidentally. We report the case of a 72-year-old male with a history of high-risk prostate adenocarcinoma previously treated with radical prostatectomy. During follow-up, the patient presented with a painless right scrotal nodule and a concurrent rise in serum PSA levels. Scrotal ultrasound and contrast-enhanced ultrasound (CEUS) revealed a solid, hypervascularized lesion in the right epididymis. PSMA PET-CT confirmed intense radiotracer uptake at the same site, consistent with metastatic disease. No other distant metastases were detected. The patient was treated with hormonal therapy and monitored through imaging and PSA levels, showing partial response. This case underscores the importance of considering atypical metastatic sites in prostate cancer follow-up. Multimodal imaging, especially CEUS and PSMA PET-CT, plays a pivotal role in the detection and characterization of rare metastatic localizations.

This case report follows a 60-year-old female with a history of hypertension, diabetes, and Factor V Leiden mutation with multiple prior deep vein thromboses (DVT) in the lower extremities who presented with right eye vision loss. Computed tomography angiogram (CTA) of the neck showed a 4 vessel arch anatomy with an absence of the left common carotid artery and separate origins of the left internal and external carotid arteries directly arising from the arch, which was an incidental finding. This case contributes to the sparse existing literature and highlights the extremely rare occurrence of complete carotid artery agenesis and its clinical implications.

Catastrophic antiphospholipid syndrome (CAPS) is a rare thrombotic disorder that can present with distinctive imaging features. Recognition of these imaging patterns is critical for timely diagnosis and management. We report the imaging findings in a 27-year-old woman presenting with acute dyspnea. Computed tomography pulmonary angiography (CTPA) revealed a large saddle embolus at the main pulmonary artery bifurcation with bilateral extension, accompanied by right ventricular dysfunction on echocardiography. The constellation of imaging findings—massive central thrombus burden, right heart dysfunction indices (RV/LV ratio 1.3, TAPSE 13mm), and absence of deep venous thrombosis—prompted consideration of an underlying thrombophilic disorder. Subsequent workup confirmed CAPS with multiorgan involvement. Following treatment with thrombolysis, corticosteroids, and plasmapheresis, follow-up CTPA at three months demonstrated complete thrombus resolution with normalization of cardiac parameters. This case illustrates the characteristic imaging appearance of CAPS-related massive pulmonary embolism and emphasizes the need to recognize high-risk features that suggest underlying systemic thrombophilia. Multimodality imaging is essential for diagnosis, risk stratification, treatment monitoring, and documenting complete resolution.
