Arteriovenous fistula after biopsy of renal transplant kidney: diagnosis and treatment.

An 11-year-old renal transplant recipient was noted to have a bruit over her transplant graft 26 months post transplant and 17 months following percutaneous renal biopsy during an episode of rejection. Diagnosis of an arteriovenous (AV) fistula was made by ultrasound examination with Doppler flow and was confirmed with arteriography. The AV fistula was occluded by transcatheter embolotherapy with placement of a steel coil into the fistula from the renal vein approach. This procedure allowed nonsurgical closure of the AV shunt without significant change in renal function.

Intracranial tuberculosis in children: CT appearance and clinical outcome.

We retrospectively evaluated the CT studies of 9 children who presented with intracranial tuberculosis during 1981-1987, and compared their radiographic appearance with the clinical outcome. The most common radiographic findings were: 1) ventriculomegaly (7/9) ,2) tuberculoma formation (6/9), and 3) infarction (4/9). Of 7 patients with ventriculomegaly, 3 required a ventricular shunt and 2 had spontaneous resolution of ventricular dilatation. Four children with ventriculomegaly were moderately or severely retarded, one had cognitive dysfunction, and one was neurologically normal. Four of six children with tuberculoma also had infarction and/or ventriculomegaly; of these four children, three were moderately or severely retarded. Two patients with tuberculoma as the only intracranial abnormality had complete resolution of the granuloma with normal neurologic outcome following antituberculous therapy. The four children with large vessel infarction also had ventriculomegaly; three had poor clinical outcome. The presence of tuberculoma alone is not necessarily predictive of poor neurologic outcome; age less than 20 months, infarct, and/or ventriculomegaly are usually associated with sequelae.

Neurenteric cyst: surgery and diagnostic imaging.

Neurenteric cysts are rare, with fewer than 30 cases noted in the literature. We report the case of a newborn infant with respiratory distress caused by a large neurenteric cyst that was identified by prenatal ultrasound. Treatment consisted of excision of the mass through a right posterolateral thoracotomy. The cyst adhered to the spine at the level of the first thoracic vertebra and communicated with the jejunum through a posterior diaphragmatic defect. Postoperative studies with magnetic resonance imaging (MRI) and computed tomography (CT) disclosed an anterior meningocele and tethering of the spinal column. This is the second reported case of a neurenteric cyst demonstrated by prenatal ultrasound. The presence of an intrathoracic cyst associated with spinal abnormalities is characteristic of this anomaly. With imaging techniques such as MRI and CT, we may detect residual intraspinal disease associated with neurenteric cysts.

The hyperdense choroid plexus: a CT finding associated with aortic arch obstruction in the newborn.

We report the first observation of choroid plexus hyperdensity depicted by CT in two newborns with aortic arch obstruction. Neither infant had intracranial hemorrhage or infarction demonstrated by autopsy or cranial ultrasonography. Although not proven, we believe that such hyperdensity in these two cases represents abnormal vascularity within the choroid plexus related to upper extremity hypertension.

Preduodenal portal vein: surgery and radiographic appearance.

Preduodenal portal vein is rare, with 63 cases reported in the literature. In general, this anomaly occurs in children with associated small bowel obstruction. We report a newborn infant who presented with duodenal stenosis, mongolism, and preduodenal portal vein. Treatment consisted of a duodenoduodenal anastomosis without mobilizing the portal vein. The correlation between imaging techniques and the operative findings is discussed. Because identification of preduodenal portal vein at surgery is important, preoperative sonography may be useful in selected cases to define the position of the vein.

Neonatal jaundice: clinical and ultrasonographic findings.

We reviewed the laboratory parameters, clinical information including presence or absence of stool pigmentation, and ultrasonographic findings in 67 patients with neonatal conjugated hyperbilirubinemia and liver biopsies. Hepatobiliary nuclear scintigraphy was done in 14 of the patients. Final diagnoses included extrahepatic biliary atresia, neonatal hepatitis, cystic fibrosis, metabolic liver disease, alpha 1-antitrypsin deficiency, bile duct stenosis, Alagille syndrome (arteriohepatic dysplasia), choledochal cyst, panhypopituitarism, and miscellaneous causes of intrahepatic cholestasis. A single diagnostic criterion is insufficient to distinguish the various causes of neonatal jaundice. Clinical laboratory values varied widely among patients with medical and surgical causes of jaundice. Absence of stool pigmentation was not specific for biliary atresia and was found in patients with medical causes of jaundice. Conversely, two patients with biliary atresia had pigmented stools at presentation. Ultrasonography was diagnostic only for choledochal cyst and bile duct stenosis. Nonvisualization of the gallbladder by either ultrasonography or nuclear hepatobiliary scintigraphy was nonspecific in the discrimination of medical from surgical causes of jaundice. A multidisciplinary approach to the evaluation of neonatal jaundice is necessary, since no single test or imaging modality can reliably define the cause in all cases.
