[Unsuspected painless subacute thyroiditis detected by radiogallium scintigraphy].

Two cases of painless subacute thyroiditis were presented in whom fever, fatigue and arthralgia except for thyroidal pain and swelling were complained. Until a intense uptake of the thyroid was found on radiogallium scintigraphy, the examinations of the thyroid had not been done. Laboratory data showed increased erythrocyte sedimentation rate, C-reactive protein and serum alkaline phosphatase, and mild leukocytosis. Skeletal, hepatic and biliary diseases were denied. In patients who have fever, increased erythrocyte sedimentation rate and serum alkaline phosphatase elevation without apparent sources, thyroid function should be evaluated because subacute thyroiditis can be associated with elevation of the serum alkaline phosphatase.

Congenital extrahepatic portocaval shunt associated with hepatic hyperplastic nodules in a patient with Dubin-Johnson syndrome.

We report a rare case of congenital extrahepatic portocaval shunt diagnosed during evaluation of hyperplastic nodules in the liver. Diagnostic imagings showed hypoplasia of the intrahepatic portal venous system and splanchnic portal venous return to the inferior vena cava through aberrant vessels. Altered hepatic blood flow dynamics due to this shunt may have been implicated in the etiology of the hepatic hyperplastic nodules.

MRI of cervical masses of thymic origin.

OBJECTIVE: Thymic diseases can arise from remnants of thymic tissues along the path of fetal descent and may simulate thyroid tumors or lymphadenopathy. MATERIALS AND METHODS: We present two patients with a cervical mass arising from the cervical thymus that was caused by incomplete descent of the thymus into the mediastinum. RESULTS: In one patient a cervical mass was surgically confirmed to be a cervical thymoma, which simulated a thyroid cancer on CT and 201Tl-scintigraphy. In another patient, cervical thymic hyperplasia arising from an incompletely descended thymus was surgically confirmed. The isointensity between the cervical mass and an enlarged mediastinal thymus was recognized on MRI. CONCLUSION: If a cervical mass is located in the region of the lower pole of the thyroid or if there is a connection or the same intensity between the cervical mass and the mediastinal thymus on MRI, a diagnosis of a cervical mass of thymic origin should be considered.

Root of the small-bowel mesentery: correlative anatomy and CT features of pathologic conditions.

The root of the small-bowel mesentery (SBM) is an important peritoneal fold that is contiguous to other peritoneal ligaments and mesocolons. Several pathologic conditions can occur in the SBM itself, and diseases that spread through the connections from adjacent organs frequently involve it. The root of the SBM is contiguous to the hepatoduodenal ligament around the superior mesenteric vein (SMV) and contiguous to the right side of the transverse mesocolon around the gastrocolic trunk. The inferior mesenteric vein, which is a landmark of the descending mesocolon, runs along the left side of the root of the SBM. Malignant neoplasms can spread to the SBM by means of direct extension, extension along the neural plexus, extension along neighboring ligaments, or extension along lymphatic vessels. Inflammatory conditions such as pancreatitis and perforation of a jejunal diverticulum can also spread to the SBM. Anomalies that can occur in the SBM include rotation anomalies and internal hernia. Vascular lesions of the SBM include thrombosis of the superior mesenteric artery (SMA), acute SMV thrombosis, SMA dissection, arterioportal fistula, and portal venous gas. Other pathologic conditions that can occur in the SBM are edema or congestion, mesenteric tear, mesenteric panniculitis, and tumors or tumorlike lesions.
