[Unilateral persistent hyperhidrosis after ischemic stroke].

A 64-year-old right hemiplegic woman, who had been treated for hypertension for 15 years, was admitted to our hospital. Neurologic examination on admission disclosed right hemiplegia and motor aphasia; however, ophthalmoparesis, pupillary abnormality, and blepharoptosis were not evident. Excessive sweating on the right side of the body, which was most marked on the face, was observed. Amount of sweating on the left side of the body was normal. Unilateral hyperhidrosis persisted for more than 2 months. MRI revealed hemorrhagic infarctions in the left basal ganglia, internal capsule, thalamus, hypothalamus, and medial part of the cerebral peduncle. 123I-IMP SPECT disclosed hypoperfusion in the left striatum, thalamus, occipital cortex, and right cerebellar hemisphere. Cerebral angiography revealed arteriosclerotic changes in the basilar artery, but that the left posterior cerebral artery and its branches were not occluded. Unilateral persistent hyperhidrosis is rare after ischemic stroke. Hypothalamic lesion was thought to be responsible for the hyperhidrosis in this patient. As the hypothalamus receives its blood supply from the posterior cerebral artery, unilateral persistent hyperhidrosis may be an important sign of cerebral infarction in the posterior cerebral artery region.

Discordant hepatic uptake of Tc-99m HIDA and Tc-99m colloid in a patient with segmental biliary obstruction.

Discordant hepatic uptake between Tc-99m HIDA and Tc-99m colloid occurred in a 63-year-old female with segmental biliary obstruction due to cholangioma. Radiographic CT and a percutaneous transhepatic cholangiogram revealed the obstructed right hepatic duct as well as the dilated intrahepatic duct in the right lobe. At surgery this was confirmed, and a 2 cm mass encasing the right hepatic duct was identified. It should be included in the gamut of discordant hepatic uptake of Tc-99m IDA and Tc-99m colloid.

The role of Ga-67 citrate imaging in pancreatitis.

Two patients with pancreatitis in whom an area of predominant uptake of Ga-67 citrate was demonstrated involving the entire pancreas are presented. Ultrasound and x-ray CT did not reveal any morphologic abnormalities in the pancreas, whereas Ga-67 citrate imaging indicated the presence of active inflammatory change. Ga-67 citrate imaging may be useful in confirming the diagnosis of acute pancreatitis or acute exacerbation of chronic pancreatitis based on clinical and laboratory data, especially when ultrasound and/or x-ray CT cannot reveal any morphologic abnormalities in the pancreas.

[Bilateral ureteral obstruction by periarterial fibrotic reactions in aortoiliac arteriosclerosis: report of a case].

A 60-year-old man visited our hospital with the chief complaint of right flank pain. A right ureteral stone was suspected by the findings of KUB and DIP, and conservative treatment was carried out. Repeat KUB and DIP a month after treatment showed that the stone shadow was not visible and right hydronephrosis had increased. Closer examinations by RP and CT scan revealed right ureteral obstruction caused by periarterial fibrosis accompanied with arteriosclerotic changes of the aortoiliac region. The arteriosclerotic changes were confirmed by pelvic arteriography, and then right ureterolysis and lateral displacement were performed. DIP four months after the operation showed improvement of right hydronephrosis, but left hydronephrosis was observed. As the same cause as the right side was suspected, left ureterolysis and intraperitoneal transposition were also performed. Histological findings of each periureteral tissue resembled idiopathic retroperitoneal fibrosis. DIP three months after the second operation showed no hydronephrosis. Case reports of ureteral obstruction due to perianeurysmal fibrosis have not been infrequent recently, but our case showed severe arteriosclerotic changes instead of conspicuous aneurysm. The possibility of occurrence of periarterial fibrosis caused by severe arteriosclerotic changes is discussed.
