Anastomosing hemangioma of liver
Anastomosing hemangiomas are a rare subtype of benign vascular hemangioma which most commonly arise in the genitourinary tract and retroperitoneum. In only a small number of reports has this entity been shown originating within the liver parenchyma. Despite their benign behavior, on contrast-enhanced computer tomography and magnetic resonance imaging studies anastomosing hemangiomas can demonstrate enhancement characteristics similar to primary and metastatic liver lesions. This case report highlights the imaging features of this entity and provides a brief review of the limited literature that exists on this rare hepatic ...

Methadone-induced Toxic Encephalopathy In Pediatric Patients: Two Case Reports
Toxic encephalopathy is a wide spectrum of encephalopathy secondary to insult from toxic substances, with variable clinical presentations from minor cognitive impairment to severe neurological dysfunction and death. Methadone-induced toxic encephalopathy is an extremely rare form of toxic encephalopathy which typically demonstrates abnormal imaging findings in the dentate nuclei or cerebellum. This is a report of methadone-induced toxic encephalopathy in two toddlers secondary to accidental ingestion. They were brought in unconscious to the emergency department of a tertiary hospital and were found to be cyanotic and pulse...

Klippel-Feil Syndrome with Sprengel Deformity
Coexistence of Klippel-Feil syndrome with Sprengel deformity and omovertebral bone is a rare complex bone abnormality with unknown incidence and etiology. Herein, we report a case of a 6-year-old girl with coexistence of these congenital abnormalities evaluated by three-dimensional computed tomography. We also make a brief review and discuss in details the role of this imaging modality in the evaluation of such complex cases. (Source: Journal of Radiology Case Reports)

Epiploic Appendagitis in a Femoral Hernia
We present a case of a 65-year-old patient who underwent clinical work-up for a tender left groin lump. When undergoing a CT scan for investigating possible lymphadenopathy, she was found to have epiploic appendagitis contained within an incarcerated left sided femoral hernia. In this case report, we review the relevant anatomy, aetiology, patient demographics, as well as clinical and imaging findings and management. (Source: Journal of Radiology Case Reports)

Leiomyosarcoma of the Inferior Vena Cava with Hepatic and Pulmonary Metastases: Case Report
We present a case of a 46-year-old female with no significant past medical history presented to the emergency department with mild abdominal pain and distention, early satiety, and weight loss for three weeks, found to have unresectable metastatic leiomyosarcoma of the inferior vena cava.

Intra-prosthetic dislocation of dual mobility hip prosthesis: an original and unusual complication
A 78-year-old female presented with dislocation of a dual mobility hip prosthesis. On standard radiographs after closed reduction, the hip prosthesis appeared to be properly reduced, but clinically the hip was unstable. A Computed Tomography showed a round foreign body, that was in fact a dislocation of the intra-prosthetic implant. This was confirmed intra-operatively during revision surgery. Intra-prosthetic dislocation is a specific complication of dual mobility system. Classically, it ' s a late complication, linked to the wear of retention area of the polyethylene insert. In this case report we describe an unusual rea...

Mycotic pseudoaneurysm of the aortic isthmus secondary to salmonella infection causing a diagnostic dilemma
We report a case of a mycotic pseudoaneurysm affecting the aortic isthmus of the thoracic aorta which is an extremely rare infection. To our knowledge no case report of mycotic pseudoaneurysm of the aortic isthmus secondary to salmonella infection has thus far been described. The specific case we present is also unique in that it posed a diagnostic imaging dilemma where the initial imaging revealed a periaortic mass which could not be accurately characterized and only on subsequent imaging reveal itself to be a thrombosed mycotic pseudoaneurysm. We hope that our case report highlights to the medical community the high degr...

Difficult diagnosis of Angiomatoid Fibrous Histiocytoma of the leg mimicking a benign condition
Angiomatoid fibrous histiocytoma is a rarely metastasizing soft-tissue tumor of low-grade malignancy. Here we report a case of angiomatoid fibrous histiocytoma located in the leg of a 15-year-old female. This case is of particular interest due to its radiological features that led to raise two questions concerning the nature of the disease (is it reactive or tumoral?) and its site of origin (within soft tissues or the tibial periosteum?). Here we describe ultrasound, magnetic resonance imaging, computed tomography scan and positron emission tomography findings that helped answer these questions, understand the real nature ...

Non-Enhanced CT Mimicking Contrast Enhanced CT - A Case Report on Polycythemia
Diffuse hyperdense cerebral vasculature is sometimes encountered on non-enhanced computed tomography, and polycythemia is one of the conditions which appears the same. The current case report is of a case of 37-year-old female patient arrived with a complaint of feeling severe headache for the past 3 days which was insidious in onset, diffuse in nature and it did not respond to any medication. NECT brain study showed the hyperdense circle of Willis and cerebral venous sinuses. Contrast was not administered for computed tomography study of the brain. On blood investigations, the patient had raised hematocrit level (74%). Th...

Peritoneal Carcinomatosis Arising from Primary Anorectal Melanoma
We present a case report of a 75 year old female with a history of transanal excision of primary anorectal melanoma who presented with increasing abdominal pain and distention. Computed tomography scan of the abdomen and pelvis showed metastatic disease to the peritoneum with findings of extensive peritoneal carcinomatosis, demonstrating the aggressive nature of anorectal melanoma.
