Giant lateral sinus pericranii. Case report.

A case of giant lateral sinus pericranii, which presented in a patient during early childhood as a soft, collapsible mass and gradually grew until it reached 13 x 9 cm when the patient was 36 years of age, is reported. The patient underwent successful surgery and the lesion was totally excised. The results of diagnostic tests (computerized tomography scanning, magnetic resonance imaging, cerebral angiography, and sinusography) and surgery-related problems are presented and discussed.

Combined transhepatic and endoscopic procedures in the biliary system.

Endoscopic biliary procedures are 89-97% successful in skilled hands. The commonest causes of failure are inability to cannulate the papilla of Vater due to difficult anatomy or tortuosity of the distal common bile duct and failure to cross a rigid biliary stricture. In nearly all of these cases, successful endoscopic procedures can be completed after percutaneous antegrade placement of a small catheter or guidewire to the duodenum. In 44 such combined procedures on 42 patients, the success rate was 43 (98%). There were two severe and eight mild complications. Combined procedures overcome the difficulties caused by tortuous biliary ducts and rigid strictures while obviating the need for more extensive percutaneous procedures and transhepatic tract dilatation.

Pontine infarction producing dysarthria-clumsy hand syndrome and ataxic hemiparesis.

We describe two patients, one with clumsy hand-dysarthria syndrome and one with ataxic hemiparesis. Both had pontine lesions on CT. Similar clinical syndromes may be seen with lesions of the internal capsule, and it is not possible to predict the lesion's location from clinical information alone. The clinical picture of dysarthria-clumsy hand syndrome or ataxic hemiparesis is also not specific for lacunar infarction.

Radiologic evaluation of epidermoid cyst.

Optimal radiologic investigation greatly improves surgical outcome in cases of epidermoid cyst. As the lesion is benign but will recur if total excision is not accomplished, the surgeon must be prepared to resect the entire capsule and not simply drain the cyst. The contribution of neuroimaging and other diagnostic procedures to the preoperative evaluation of a man with posterior fossa cyst is reported.

Computed tomography in the evaluation of sarcomatous tumors of the thigh.

CT examination of a soft tissue mass in the lower extremity adds substantially to a more precise preoperative histologic diagnosis and anatomic localization of the lesion. An appreciation of the normal cross-sectional anatomy of this region is essential for adequate evaluation of the information provided by the CT scan. Four patients with sarcomatous tumors involving the soft tissues of the thigh are described and the diagnostic information provided by CT is discussed. In two of these cases anatomic cross sections are correlated with the CT scan.

Involvement of an aberrant right subclavian artery in dissection of the thoracic aorta: diagnostic and therapeutic implications.

There have been few reports of an aberrant right subclavian artery in patients with aortic dissection. The diagnostic and therapeutic implications of the association of these two abnormalities are important and potentially ominous. Two patients with extensive type III dissections of the thoracic and abdominal aorta are described. In one patient, extension of the dissection into the aberrant right subclavian artery led to eventual exsanguination into the esophagus. In the second patient, cross-clamping of the abdominal aorta proximal to the left subclavian artery at surgery resulted in complete cutoff of blood supply to both vertebral arteries and the patient's subsequent demise.

"Cold" lesions on bone imaging.

Photon-deficient foci or "cold" lesions were demonstrated on 99mTc-polyphosphate bone imaging in eight individuals with various malignancies and one in sickle cell crisis. The bone radiographs of five of these persons failed to show corresponding bony changes at the time of the imaging. Most of the "cold" lesions observed on bone imaging were located in the denser and tubular bones. A postulate has been advanced regarding the factors that might influence the different gamma-imaging manifestations of radiographically demonstrable lytic lesions. The cases presented herein further emphasize the importance of recognizing the existence of "cold" areas in the images of bones and the need to place these in proper perspective when interpreting scans.
