ABSTRACT
We describe a rare case of solitary metastasis of follicular carcinoma of the thyroid gland into the petroclival region in a 58-year-old woman. The metastasis was the first and only manifestation of the disease. The histology of the tumor, differential diagnosis and clinical course are discussed. In a few similar cases described so far the tumor was always a well or moderately differentiated follicular carcinoma located in the petroclival region. As in this presentation, these cases also clinically mimic a meningioma. The differential diagnosis includes adenoma of the thyroid gland and thyroid gland dystopia. We demonstrated the primary focus of carcinoma within the thyroid after its detailed examination initiated by our finding. The clinical outcome of such rare cases is usually excellent, much better than in metastases of papillary carcinoma into the brain.

The total of 1,931 patients had been operated on in the Second Department of Surgery, Faculty Hospital and Policlinic, in Olomouc for thyroid disorders. The present paper deals with the operation on the thyroid gland in advanced age. The symptoms of the disease, types of interventions and kinds of complications, factors influenced by age and the secondary diseases are pointed out. In these terms, a group of 69 patients older than 60 and operated on within the period of 1981-1987 are analyzed in detail.

The final value of portal blood flow pressure depends on the degree of vascular obstruction, then on the resistance in collateral vessels and, last, on splanchnic blood flow. The iniciating cause of portal hypertension most often lies in advancing anatomical damage leading to increased resistance and, consequently, to a reduction of portal blood flow, and simultaneous reciprocal development of extrahepatic collaterals. The determination of a true portal flow is a necessity particularly when deciding about a shunt surgery and its type, but it also supplies valuable information on the degree of portal flow restriction and, in this way, on the progress of pathophysiological changes, their extent and advance. The technique of radionuclide angiography and determination of the hepatic perfusion index (HPI) proposed by Sarper appears to be a profitable noninvasive method supplying well reproducible information on portal blood flow. Sarper proved it to be correlated with the degree of portal hypertension established by angiography. Ultrasonographic criteria of portal hypertension include dilatation of the portal vein in the region of the hilus hepatis exceeding 15 mm, and a more than 10 mm dilatation of the splenic vein above the spine. The mean HPI value obtained from the examination of 19 subjects without liver involvement was 0.6956 +/- 0.0583. The group of chronic hepatopathies included 19 patients with bioptically verified chronic hepatitis without reconstruction and/or steatosis, and 32 patients with liver cirrhosis likewise confirmed by biopsy: portosystemic shunts could be demonstrated in 14 of the latter.
