Duplication of the vermiform appendix.

In this brief report, the authors present a case of duplication of the vermiform appendix with appendicitis occurring in both appendices and causing small bowel obstruction.

A case of massive thymolipoma.

A massive anterior mediastinal tumor was discovered in a 9-year-old girl with long-standing symptoms of asthma. Preoperative computed tomography (CT) scan and magnetic resonance imaging (MRI) results suggested the presence of a thymolipoma, a rare benign tumor of the thymus. Few cases have been reported in the literature, although the histological and radiographic features have been well described.

Spontaneous resolution of antenatally diagnosed adrenal masses.

Four infants had adrenal masses detected prenatally, through ultrasonography, between 18 and 30 weeks' gestation. Two were predominantly cystic, and two were solid. The sizes ranged from 0.

Primary omental torsion in children.

Primary torsion of the omentum is an unusual cause of an acute abdomen and commonly mimics acute appendicitis. The following report of four obese children is supportive of obesity as a predisposing factor. The paucity of gastrointestinal symptoms, anorexia, nausea, vomiting, and the relatively long duration of symptoms, may increase the index of suspicion.
