• Cartilage lesions are very common after patellar dislocation. • The severity of cartilage lesions increases with number of dislocations. • Osteoarthritis is common after recurrent patellar dislocation, even in young patients. • Detecting cartilage lesions is important after patellar dislocation.

A 15-month old boy presented with an abdominal swelling and early development of secondary sexual characteristics for the last 5 months. The mass was initially suspected to be of adrenal origin. Radiological and biochemical (hormonal) findings diagnosed the case to be a hepatoblastoma later confirmed by histopathological examination. Hepatoblastoma, an aggressive primary liver tumor, is a rare form of childhood malignancy and a rare cause of precocious puberty compared to the more common adrenal causes including congenital adrenal hyperplasia, adrenal tumors and the testicular tumors. Thus, when virilization occurs postnatally in boys, or girls presenting with ambiguous genitalia at birth, a virilizing adrenocortical tumor is usually given the first consideration (according to its frequency of incidence), followed by CNS causes. Rarely does one think of the other possibilities. This report describes the typical presentations and clinical features of hepatoblastoma highlighting its usual radiological features. Ibrahim Med.

A primary extra-adrenal retroperitoneal ganglioneuroma was found incidentally in a 22-year-old woman during screening for suspected pregnancy by transvaginal ultrasonography (TVS) and subsequently by magnetic resonance imaging (MRI). TVS and MRI revealed well defined solid mass in retroperitoneal at the level of L5 to S2 vertebrae and displace right common iliac and external iliac vessels. Limited cuts of the region of Computed tomography (CT) were taken and no calcification was identified. Histological examination showed that the lesion was an extra-adrenal retroperitoneal ganglioneuroma composed of mature ganglion cells and subsequently confirmed by immunohistochemistry.
