Case Report: Delineated Radiocolloid Hepatic "Hot Spot" With Superior Vena Caval Obstruction
نویسنده
چکیده
When imaging the liver in the presence of superior vena caval obstruction, a region of increased radiocolloid uptake may occur in the area of the porta hepatis. Recently, this was demonstrated with a 32-year-old male patient. With advances in electronic spatial resolution, however, the imaged "hot" area is now considerably better delineated. This artifact within the liver in the presence of superior vena caval obstruction is thought to be due to collateral intrahepatic circulation in the liver's caudate lobe.

"Hot spot" on hepatic scintigraphy [Persian]
Filling defects are often observed on 99mTc sulfur colloid liver scans. Hot spots are much less frequently seen. Superior vena cava syndrome is the most frequent cause of this finding. In this report 3 patients with S.V.C and budd - Chiari syndrome with HOT SPOT on liver scan are presented. Mechanisms of scintigraphic patterns are reviewed.
متن کاملSuperior vena caval stenosis: a complication of transvenous endocardial pacing.
Superior vena caval obstruction is a rare complication of transvenous endocardial pacing and is usually the result of thrombus formation round the pacing electrode (Kosowsky and Barr, 1972). We report a case of superior vena caval obstruction without thrombus formation secondary to localised stenosis at the site of the proximal cut end of a retracted endocardial electrode. This complication of ...
متن کاملIntimal sarcoma of the superior vena cava.
A case of superior vena cava syndrome caused by a primary intimal sarcoma of the superior vena cava is described. The known causes of superior vena caval obstruction are discussed, together with the difficulties in identifying the underlying lesion. The possibility of a primary superior vena caval neoplasm as a cause of superior vena caval obstruction should be considered in patients presenting...
متن کاملSuperior vena caval system obstruction caused by benign endothoracic goiter.
The superior vena caval syndrome caused by a substernal thyroid is a rare occurrence. It can, however, result from external compression of the superior vena cava or innominate veins by an intrathoracic goiter. This report details such a case in which innominate vein occlusion was documented both by conventional venography and by a new technique utilizing a radionuclide (sodium pertechnetate 9#{...
متن کاملComplete occlusion of the superior vena cava with chronic mediastinitis in a case of generalized actinomycosis.
Ochsner and Dixon (1936), in a review of world literature, cited 120 cases of supenor vena caval thrombosis. Twenty-eight of these were due to chronic mediastinitis, of which eleven were stated to be due to syphilis, ten to tuberculosis, one to pyogenic infection, one to trauma, and five of unknown aetiology. Tubbs (1946) reported three further cases of superior vena caval obstruction, one of w...
