Primary Intestinal Lymphangiectasia: Diagnostic Accuracy of 99mTc-Labeled Human Serum Albumin Nanocolloid SPECT/CT Before Biopsy.

Primary intestinal lymphangiectasia is an unusual cause of protein losing enteropathy due to either congenital malformation or obstruction of lymphatics of intestine. The disease can affect all or only a small part of the small intestine. Peripheral lymphedema may be associated.

Dysplastic hepatic nodules: radiological abnormalities and histopathological correlations.

Pathological studies of explanted cirrhotic livers have made it possible to define precisely the principal morphological characteristics of the transitional stages of the regenerative nodule to dysplastic nodule to hepatocellular carcinoma. The aim of our study was to examine the imaging features of histologically proven dysplastic nodules and to compare them with their histopathological features. A large majority (63%) of the dysplastic nodules in our series was hypervascular and 16% had the classic appearance of hepatocellular carcinoma.
