Bronchial walls in the radiological diagnosis of asthma.

Although bronchial wall thickening is known to occur in asthma, its radiological visibility and significance are matters of dispute. The present study shows that thickening can be detected in the plain chest radiographs of patients with severe asthma, but it cannot be reliably detected in patients with mild asthma. Measurements of bronchi made on lung tomograms showed that the lumen-wall ratio more clearly separated the asthma and normal groups than did observation of bronchial wall thickness alone.

Avulsion of nerve rootlets with the Cuatico needle during Pantopaque removal after myelography.

Three cases of histologically proven nerve root avulsion during Pantopaque removal with a Cuatico needle are described. While use of such multihole needles poses some risk to patients, we feel the advantages outweigh the disadvantages, particularly when a large volume of Pantopaque has to be removed. To minimize the possibility of nerve root avulsion, we recommend minimal manipulation of the needle and cannula during Pantopaque removal, use of gentle suction, termination of suction and injection of cerebrospinal fluid if pain occurs, and slow withdrawal of the cannula and stylet.

Computerised axial tomography in patients with severe migraine: a preliminary report.

Patients suffering from severe migraine, usually for many years, have been examined by the EMI scanner between attacks. Judged by criteria validated originally by comparison with pneumoencephalography, about half of the patients showed evidence of cerebral atrophy. Perhaps of more significance than generalised atrophy was the frequency of areas of focal atrophy and of evidence of infarction.

Pseudo-metastases in the liver: a presentation of the Budd-Chiari syndrome.

Angiographic and scintigraphic findings closely mimicked vascular liver metastases in a young woman whose Budd-Chiari syndrome is probably the result of oral contraceptive use. Histological proof should be obtained before the diagnosis of hepatic neoplasm is accepted in patients with this syndrome.

The biliary system in primary biliary cirrhosis. A study by endoscopic retrograde cholangiopancreatography.

Endoscopic retrograde cholangiograms from 23 patients with primary biliary cirrhosis (PBC), 10 controls with either normal livers or hepatocellular disease, and 4 patients with sclerosing cholangitis, were compared. Of the PBC group, 39% had gallstones. The calibers of the common bile duct and left and right intrahepatic ducts were comparable in the PBC and control groups. The small intrahepatic ducts, while normal in the control group were abnormal in 7 of the 23 PBC patients. These small ducts were irregular in caliber and had a tortuous course. The changes were not related to the presence of gallstones or the duration of the disease, but all the patients had histologically proven cirrhosis. Two patients with cirrhosis had normal intrahepatic ducts. We conclude that whereas the major bile ducts are normal in PBC, there is a high incidence of gallstones (39%), and the changes that do occur in the intrahepatic ducts are probably related to the distorted hepatic architecture due to cirrhosis and may be used as a sign that cirrhosis has supervened.

Benign osteoblastoma of the maxillary sinus.

Benign osteoblastoma is an uncommon fibro-osseous neoplasm with a predilection for the vertebrae and long bones, and a 2-to-1 male-to-female ratio of occurrence. Peak incidence occurs in the second decade, with 80% of all patients being under 30 years of age. The clinical, radiographic, and histologic presentation of a large maxillary sinus osteoblastoma is reviewed. Preoperative embolization of this vascular neoplasm is advocated.
