CT findings of small bowel trichobezoar.

A 14-year-old girl presented to our emergency room with abdominal pain and persistent vomiting. A plain radiograph of the abdomen showed features of small bowel obstruction, with dilated loops of small bowel and a mottled gas and debris pattern in the stomach and right lower quadrant. A CT scan of the abdomen and pelvis obtained to exclude appendicitis showed the distinctive appearance of a trichobezoar.

Periosteal reaction with normal-appearing underlying bone: a child abuse mimicker.

Any irritation or disruption to the underlying bone will cause a periosteal reaction and result in new periosteal bone deposition. Periosteal bone formation may be due to either physiologic or pathologic causes. Pathologic bone formation generally results from an adjacent inflammatory process or a hypoxic or toxic stimulus.

Characteristic pancreatic injuries secondary to child abuse.

A review of the most common visceral injuries which arise as a result of child abuse is presented. Duodenal and pancreatic injuries are the most characteristic injuries secondary to abuse. The clinical presentation may not be suggestive of the nature of the patient's injury, and these descriptions may help the radiologist to discern their true etiology.

Tracheal web.

Congenital tracheal web is a rare entity often misdiagnosed as refractory asthma. Clinical suspicion based on patient history, examination, and pulmonary function tests should lead to its consideration. Bronchoscopy combined with CT imaging and multiplanar reconstruction is an accepted, highly sensitive means of diagnosis.

Tracheoesophageal fistula (H-type) in neonates with imperforate anus and the VATER association.

We report three patients with imperforate anus and other stigmata of the VATER syndrome who were diagnosed as having tracheoesophageal (TE) fistula, H-type, with intact esophagus. The fistula was diagnosed in two of the three patients only after recurrent respiratory infections.

Imaging neuroblastoma in children.

Neuroblastoma is a common solid tumor of childhood that can involve the abdomen, thorax, pelvis, or the head and neck. The clinical manifestations are dependent on the widespread distribution of neural crest tissue and the length of the sympathetic chain involvement. Abdominal pain and hypertension may occur as a result of renal vasculature compression; respiratory distress may be evident in thoracic tumors; and Homer's syndrome or heterochromia of the iris may manifest from neuroblastoma of the head and neck.

Multiple fetuses in fetu:imaging findings.

Fetus in fetu is an extremely rare developmental abnormality secondary to abnormal embryogenesis in a diamniotic monochorionic pregnancy. It occurs when a vertebrate fetus is enclosed within the abdomen of a normally developing fetus. This report describes the prospective diagnosis of fetus in fetu by findings on a plain radiograph and CT scan.

Horseshoe adrenal gland in association with asplenia: presentation of six new cases and review of the literature.

Background: Asplenia syndrome is a form of heterotaxy characterized by bilateral right-sidedness. Congenital fusion of the adrenal glands ("horseshoe adrenal gland") is a less common feature of asplenia syndrome, most instances of which have been found at autopsy.

Purpose: To present clinical and imaging features of infants diagnosed with asplenia syndrome and horseshoe adrenal gland.
