Small intestinal lipomas: diagnostic value of multi-slice CT enterography.

Aim: To analyze the clinical and imaging features of the small intestinal lipomas and to evaluate the diagnostic value of multi-slice computed tomography (CT) enterography.

Methods: Fourteen cases (one had two intestinal lesions) of surgically confirmed lipomas of the small intestine were retrospectively analyzed. The location, size, clinical and radiological aspects were discussed.

Solid-pseudopapillary tumor of the pancreas: CT and MRI features of 3 cases.

Background: Solid-pseudopapillary tumor of the pancreas is a rather rare but low-grade malignant tumor with good prognosis after surgical excision.

Methods: In 3 patients with solid-pseudopapillary tumor of the pancreas which were proved pathologically, the imaging features (CT in all and MRI in one patient) of the tumor were analyzed.

Results: In the 3 female patients under 35-year-old who presented no jaundice, CT revealed that huge solid-cystic masses of the pancreatic head with calcification in one and slight dilation of the pancreatic duct in another, but without dilation of the bile duct system in all.

[Angiographic diagnosis of gastrointestinal stromal tumors].

Objective: To investigate the angiographic feature and its diagnostic value in gastrointestinal stromal tumor (GIST).

Methods: Twelve patients with pathologically proved GIST underwent angiography using PUCK and DSA one week before operation. The origin, size, morphology and angiographic appearance of the lesion were retrospectively analyzed.

Imaging features of ciliated hepatic foregut cyst.

Ciliated hepatic foregut cyst (CHFC) is a very rare cystic lesion of the liver that is histologically similar to bronchogenic cyst. We report one case of CHFC that was hard to distinguish from solid-cystic neoplasm in imaging features. Magnetic resonance imaging was helpful in differentiating these cysts from other lesions.

Angiographic findings of gastrointestinal stromal tumor.

Aim: To discuss the angiographic features of gastrointestinal stromal tumor (GIST) and to evaluate their diagnostic role.

Methods: Twelve patients with pathologically proved GIST underwent angiography (DSA)1 wk before operation, using Puck and digital subtraction DSA. The origin, size, morphology and angiographic appearance of the lesions were reviewed.

[Radiological features of primary pulmonary non-Hodgkin lymphoma: report of three cases].

Objective: To describe the radiographic and CT findings of primary pulmonary non-Hodgkin lymphoma (PPL),and to evaluate percutanous transthoracic needle biopsy (PTNB) in the diagnosis of PPL.

Methods: Chest radiographs and CT scans of three patients with histologically proven PPL were reviewed. The diagnosis of PPL was confirmed histologically with specimens obtained by means of PTNB.
