摘要:

Anterior and posterior radionuclide cerebral flow studies and brain images were performed on two patients with surgically proven subdural hematoma. In both patients, the posterior flow study showed perfusion defects corresponding in location to the static image abnormalities. The anterior radionuclide flow study was negative in both patients, even though the abnormality in one of the patients was more anterior than posterior in location. On the basis of these cases, it is suggested that the performance of a posterior radionuclide flow study in suspected subdural hematoma might provide useful information not obtained on the routine anterior study.

摘要:

Metastatic soft tissue calcification is known to occur in hypercalcemia and is usually present in the kidneys, stomach and lungs.1-3This case presents two unusual features: 1) ectopic parathormone production in association with poorly differentiated lymphocytic lymphoma; and 2) uptake of99mTc-pyrophosphate in the liver in the absence of demonstrable abnormality at autopsy. The more usual sites of metastatic calcification also showed uptake of the radionuclide. We will discuss metastatic soft tissue calcification, ectopic parathyroid hormone production, hypercalcemia in malignancy and bone scan agent localization in soft tissues.

摘要:

Administration of cimetidine prior to pertechnetate imaging in two patients with Meckel's diverticulum resulted in demonstrating the abnormality with unusual clarity. This is presumed due to the cimetidinemediated retention of pertechnetate in the gastric mucosa. Pertechnetate imaging in two normal subjects with and without cimetidine administration disclosed a marked difference in retention of the radionuclide in the gastric mucosa and its subsequent transit into the intestinal tract. Pertechnetate imaging in conjunction with cimetidine administration appears to result in markedly improved identification of Meckel's diverticulum.

摘要:

The case history of a patient with Budd-Chiari syndrome (BCS) is described. The underlaying disease proved to be essential thrombocytosis. Congenital elliptocytosis was also present. The value of the conventional liver scan, percutaneous splenoportoscintigraphy and isotopic phlebography of the inferior vena cava in the diagnosis of BCS is described. It is suggested that a combination of these three noninvasive techniques be used when BCS is suspected.

摘要:

Hereditary elliptocytosis is an intrinsic red cell abnormality and 12% of elliptocytic individuals demonstrate hemolysis. Using tracer kinetic methodology (51Cr labeled RBC's) the destructive phase of erythropoesis was assessed in two healthy subjects receiving labeled donor red blood cells from individuals with hereditary elliptocytosis. The red blood cell survival time of transfused elliptocytes was significantly decreased in both recipients, with a survival half-time (T½) of 19 days in one recipient and 20 days in the other (n 27 days). Abnormal splenic sequestration was also demonstrated. The decreased survival of transfused cells suggests that caution should be exercised in utilizing patients with hereditary elliptocyosis as donors in blood banking operations even in the absence of evidence of hemolysis.

摘要:

Using a triiodothyronine withdrawal method to produce a hypothyroid state in 38 patients with prior thyroidectomies for differentiated thyroid cancer, 56 H-TSH and T4 levels were measured prior to metastatic survey scans performed with131I. All the T4 levels were below normal and 55 of the 56 H-TSH levels were elevated. No qualitative differences could be observed in the eight patients who had scans performed after bovine TSH injections and later after triiodothyronine withdrawal. Triiodothyronine withdrawal does induce high endogenous TSH levels and under normal circumstances bovine TSH injections are not required for metastatic scans in patients with thyroid cancer.

摘要:

Radionuclide brain scans and cerebral blood flow studies have become highly sensitive but they remain quite nonspecific diagnostic modalities. Previous reports have discussed similarities between Paget's disease of bone and subdural hematoma on radionuclide studies. We encountered a case in which Paget's disease produced all the described manifestations of subdural hematoma. The differential features of the two conditions and their pathophysiological bases are discussed.
