[Isolated pulmonary supravalvular stenosis accompanied by pulmonary artery aneurysm]. / Izole kapak üzeri akciger atardamar darligi ve akciger atardamari anevrizmasi

We present a 19-year-old asymptomatic female patient in whom isolated pulmonary supravalvular stenosis and pulmonary artery aneurysm were incidentally detected. On cardiologic examination, a systolic murmur was heard over the lungs, right axis deviation was seen on the electrocardiogram, and marked appearance of the pulmonary artery was noted on the chest X-ray. On transthoracic echocardiography, the pulmonary artery trunk was found to be wider than normal, and there were mild pulmonary and tricuspid regurgitation. Color Doppler examination showed a turbulent flow 2 cm distal to the pulmonary valve. Transesophageal echocardiography showed a supravalvular membranous structure and a proximal pulmonary artery aneurysm. The pulmonary artery trunk was measured as 40 mm at the widest part. Thoracic computed tomography revealed that the proximal pulmonary artery aneurysm was localized to the pulmonary artery trunk and measured 41 mm. As the patient was asymptomatic and there were no signs of aneurysmatic compression or a left-to-right shunt, and due to the presence of a relatively low gradient (16 mmHg) across the stenotic area, she was scheduled to regular radiologic control.

Sinonasal schwannoma of the middle turbinate.

Paranasal schwannomas are uncommon lesions, representing less than 4% of all head and neck schwannomas. They give rise to nonspecific symptoms such as nasal obstruction, epistaxis, and anosmia. Imaging features are generally nonspecific. Here, we present the radiologic features of a benign schwannoma of the middle turbinate with dural invasion in a 71-year-old woman.

Remote cerebellar hemorrhage after lumbar spinal surgery.

BACKGROUND: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. METHODS: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. RESULTS: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. CONCLUSION: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

Complications of continuous ambulatory peritoneal dialysis: evaluation with CT.

PURPOSE: To assess the frequency of abdominal computed tomography (CT) findings of continuous ambulatory peritoneal dialysis (CAPD)-related complications. MATERIALS AND METHODS: CT examinations of 42 patients (23 females and 19 males; median age, 46.5 years; age range, 22-70 years) with end-stage renal disease receiving CAPD were investigated retrospectively. CT examinations were performed with a suspicion of CAPD-related complications who were admitted to dialysis unit with various complaints. Images were obtained from the level of the dome of the diaphragm to the pelvis with an 8-mm slice thickness before and after intravenous contrast injection. Oral contrast material was performed in 17 of these patients. CT peritoneography was performed in one patient. RESULTS: Complications of CAPD detected on CT studies included peritoneal thickening (n = 19; 45.7%), peritoneal calcifications (n = 2; 4.7%), peritoneal enhancement (n = 2; 4.7%); intraperitoneal loculation of fluids (n = 16; 38.1%), dilatation of bowels secondary to adhesions (n = 3; 7.1%); leakage of dialysis fluid adjacent to the entry site of the CAPD catheter (n = 6; 14.3%)(leaked dialysis fluid was loculated near the catheter in 4 of these patients); abscesses (n = 3; 7.1%); hernias (n = 5; 11.9%); hematomas (n = 5; 11.9%); tuberculous lymphadenitis (n = 2; 4.7%); bowel perforation (n = 2; 4.7%); ischemic bowel disease (n = 1; 2.4%); acute pancreatitis (n = 2; 4.7%); and catheter malposition (n = 1; 2.4%). CONCLUSION: CT of abdomen is useful in detection of CAPD-related complications. Peritoneal thickening and intraperitoneal loculation of fluids due to peritonitis were the most common complications of CAPD detected on abdominal CT.

Mushroom poisoning in children: liver MDCT findings in three cases.

Wild mushroom poisoning occurs quite frequently in Turkey, usually during late summer and autumn when climatic conditions favour fungal growth. We report the MDCT findings of the liver in three children after mushroom poisoning. In all three patients, precontrast MDCT findings showed diffuse reduction of hepatic attenuation compared with the spleen. Contrast-enhanced MDCT images showed homogeneous contrast enhancement of the liver. All three patients recovered after medical treatment. A follow-up precontrast MDCT examination was performed in one patient in whom the density of the liver parenchyma had returned to normal.
