Abstract: Acute traumatic aortic injury is a potentially lethal condition with most patients die at the scene of the accidents. Rapid deceleration due to motor vehicle accidents is the commonest mechanism of injury. These injuries can be successfully repaired in the few patients who survive the initial trauma if proper diagnosis and rapid treatment are provided. The occurrence of acute traumatic aortic injury in patients with congenital abnormality of the aortic arch has been rarely reported; however, it renders the diagnosis and treatment more difficult. In this paper, we describe an extremely rare case of aortic injury in a young patient who had a right sided aortic arch with rupture of an aberrant left subclavian artery. The patient was suspected to have a Kommerell`s diverticulum in the aberrant subclavian artery origin. This injury resulted in an unusually huge pseudoaneurysm involving part of the mediastinum and extending into the neck. Unfortunately; patient succumbed in spite of surgical intervention.

Abstract: We describe a case of a female with simple virilizing congenital adrenal hyperplasia (CAH) reared as a male diagnosed at the late age of 64. Computed Tomography (CT) demonstrated a large adrenal mass, bilateral diffuse adrenal enlargement, female pelvic organs as well as a clearly visualized prostate gland. This is to the best of our knowledge the first case of such a sizable prostate gland in a female CAH patient documented on CT. We review the literature regarding aspects where radiologists may encounter CAH and the finding of presence of a prostate gland in female CAH patients.

Abstract: Coronary sinus anomalies are rare. They can be associated with other vascular anomalies such as persistent left superior vena cava or can occur in isolation. We present a rare case of an isolated coronary sinus communication to the left atrium. This anomaly may be clinically relevant in the setting of significant left-to-right shunting or when shunt reversal results from right-sided heart failure. It may also be significant in cases of persistent atrial fibrillation after attempted pulmonary vein isolation.

Abstract: Pathologic dilatation of the maxillary sinus by air is a rare condition with unclear etiology. We present a case of a 17 year old male with a maxillary air cyst diagnosed by computed tomography. The CT demonstrated air-filled expansion of the maxillary sinus beyond the normal anatomical limits with associated cortical bone thinning. The case report highlights the pathognomonic computed tomography findings of this rare entity and discusses the perplexing nomenclature, proposed etiologies and various treatment options.

Abstract: Gallbladder torsion is a rare cause of acute gangrenous cholecystitis; its occurrence within an abdominal hernia has not been previously reported. We present such a case occurring within a parastomal hernia and imaged with unenhanced CT.

Abstract: A 31-year-old nulliparous woman visited our hospital complaining of abdominal distension. Abdominal ultrasonography and computed tomography revealed a 40 × 40 × 30-cm, multilocular cystic mass extending from the upper abdomen to the pelvis. Magnetic resonance imaging (MRI) revealed a cystic tumor that was hypointense on T1-weighted images and was heterogeneously hyperintense on T2-weighted images. The final diagnosis was an 8 kg leiomyoma with cystic degeneration. Uterine leiomyomas are common benign tumors in females of reproductive age. However, subserosal leiomyomas with complete cystic degeneration of the retroperitoneal space are rare, and they are difficult to accurately diagnosis without pathological examination.
