Primary localized amyloidosis of the urinary bladder.

We report a rare case of localized form of primary amyloidosis (amyloidoma) of the urinary bladder with CT and MR findings. Clinically, it is difficult to distinguish from invasive transitional cell carcinoma and inflammatory lesion. We think that the MR intensity on T2-weighted images is helpful in making the diagnosis.

[Imaging findings of pulmonary vascular disorders in portal hypertension].

Purpose: The purpose of this study was to demonstrate and compare the imaging findings of hepatopulmonary syndrome and portopulmonary hypertension.

Materials And Methods: We retrospectively reviewed the imaging findings of five patients with hepatopulmonary syndrome and four patients with portopulmonary hypertension. We evaluated chest radiographs, chest and abdominal computed tomography (CT) scans, 99mTc-macroaggregated albumin (MAA) lung perfusion scans, and pulmonary angiograms.
