Congenital diaphragmatic eventration associated with massive hiatal hernia.

Congenital eventration of the diaphragm is uncommon. Its association with a hiatal hernia has not been reported earlier. We report a case of such an association in a 2-month-old boy who presented with tachypnea aggravated by feeding and recurrent vomiting.

Mesenteric cystic teratoma in children.

Mesenteric teratoma is an extremely rare tumor, arising, akin all other teratomas, from totipotent primordial cells and displays a mixture of tissues of tridermal or bidermal origin. Two cases of mature mesenteric teratoma in a 5-month-old girl and a 4-month-old boy, the youngest reported in the literature, excluding a case recently diagnosed prenatally, are described. Diagnostic tools, differential diagnosis and management are also discussed.

Mesenteric cystic lymphangioma.

Abdominal cystic lymphangioma is a very rare congenital tumor of lymphatic origin. It usually appears in the pediatric age and frequently presents with non-specific symptoms and deceptive signs causing, at times, diagnostic dilemmas. Ultrasonography and computer tomography imaging are considered the diagnostic modalities of choice.

Lipomatosis of the parotid gland in children.

Parotid lipomatosis is extremely rare in children. Only 4 cases have previously been reported in the English language medical literature. Surgical excision is frequently complicated by recurrence.

Successful separation of thoracopagus conjoined twins.

The first successful separation of thoracopagus conjoined twins in Eastern Saudi Arabia with 2-year follow up is presented. Physical examination and radiographic studies revealed a conjunction that extended from midsternum to a common umbilicus. The shared internal organs included liver and pericardium.

Complete separation of the testis and epididymis presenting as inguinal hernia.

Complete separation of the epididymis from the testis is a rare phenomenon. In all reported cases, both structures remained undescended. We recently managed a 2-month-old boy with bilateral inguinal hernia and complete dissociation of the epididymis from the testis on the left side.
