Two patients with chronic bilateral subdural hematomas developed symmetrical generalized choreiform movements. In one patient the chorea disappeared after evacuation of the hematomas, and in the other the movement improved. The latter patient has a family history of Huntington's disease.

BACKGROUND: To compare half-Fourier acquisition single-shot turbo spin-echo spin-echo (HASTE) magnetic resonance cholangiopancreatography (MRCP) with two-dimensional turbo spin-echo (2D TSE) MRCP for imaging pancreatobiliary diseases. METHODS: Twenty-seven patients with biliary or pancreatic disease underwent MRCP on a 1.0-T scanner with a body phased-array coil. A T2-weighted HASTE sequence (18 s) and a T2-weighted 2D TSE sequence (45 s) were used during a breath-hold by the patient. The source images and maximum intensity projection images of both sequences were reviewed independently by two radiologists. RESULTS: Motion artifacts were more severely pronounced with 2D TSE sequences than with HASTE sequences (p < 0.001). All obstructions and their sites were accurately identified with both sequences. Filling defects (calculi) in bile ducts were identified in all 22 segments (100%) with HASTE-MRCP, whereas calculi in 19 of 22 segments (86%) were identified with 2D TSE-MRCP (p = 0.25). Three missed sites on 2D TSE-MRCP were intrahepatic bile ducts. CONCLUSIONS: HASTE-MRCP is superior to 2D TSE-MRCP in terms of detecting motion artifacts and visualization of the pancreatic ducts. HASTE-MRCP is comparable to 2D TSE-MRCP for visualization of the biliary ducts and their obstruction and is superior to 2D TSE-MRCP for identification of calculi in intrahepatic bile ducts.
To compare the specific information provided by ultrasound (US) and galactography and to appreciate the clinical applicability of US as a primary diagnostic method for breast tumors associated with nipple discharge, a comparative study of each method in 15 patients with ductal tumors of the breast was performed. To evaluate the smallest anatomical unit of the lactiferous system demonstrable by US, 30 patients with normal lactating breasts were examined prospectively. The smallest anatomical ductal unit that could be evaluated with US in the normal lactating breast was the terminal duct lobular unit (TDLU). US is superior to galactography in detecting masses smaller than 0.5 cm or lesions involving multiple ducts. Galactography is better for visualizing the duct system and detecting calcification. In conclusion, US serves as a primary noninvasive diagnostic tool in patients with clinically suspicious breast tumor associated with bloody nipple discharge, but galactography also should be done in specific circumstances.
PURPOSE: Our goal was to evaluate CT findings of tuberculous abscess in the retromammary region of the breast. METHOD: Four patients with tuberculosis extending from the retromammary region to the pleura were examined by CT and the findings were evaluated. All cases were also examined with mammography and two cases were evaluated with sonography. Diagnosis was confirmed by acid-fast bacillus stain, culture, and histologic examination. RESULTS: Mammography showed relatively smoothly marginated, round mass density in two cases, nodular density in one, and focal bulging of the pectoral wall in one. A sonogram demonstrated in two cases a fistulous connection from the heterogeneous, fluid-containing lesion with floating internal debris in the retromammary region to the thoracic cavity. In all four cases, CT showed relatively smoothly marginated, inhomogeneous, hypodense lesions with surrounding rims of the cold abscess type. A direct fistulous connection from the retromammary lesion through the thoracic wall into the pleura was seen in two cases. Destroyed rib fragments within the abscess were noted in two cases. CONCLUSION: A tuberculous abscess in the retromammary region usually showed on CT a focal, smoothly marginated, inhomogeneous, hypodense lesion with a surrounding enhancing rim. A direct fistulous connection with the pleura or a destroyed rib fragment in the abscess as revealed by CT can be helpful in the differential diagnosis of other infectious types of retromammary abscess.

Phlegmonous enteritis is a rare infective inflammatory disease of the intestine, predominantly involving the submucosal layer. It is difficult to diagnose and often fatal. Its association with alcoholism and various liver diseases, although rarely reported, is well documented. We report a case of phlegmonous enteritis in a male patient with congestive heart failure and colon cancer, and describe the ultrasonographic and CT findings.
