[Initial experience of magnetic resonance imaging-guided vacuum-assisted breast biopsy].

Almost all mammary lesions are detected by a mammography and an ultrasound. However, a small part of lesions cannot be shown by only a magnetic resonance imaging (MRI). MRI-guided vacuum-assisted breast biopsy is a very useful means for the pathological diagnosis of these lesions.

Inflammatory Polyp of the Gallbladder Mimicking Early Polypoid Carcinoma.

We treated a 69-year-old male with a 16-mm polyp of the gallbladder. Enhanced computed tomography demonstrated marked enhancement. With a tentative diagnosis of early polypoid cancer of the gallbladder, open cholecystectomy was performed.

Glomus tumor of the omentum: a case report.

Computed tomography revealed a well-enhanced omental mass. Magnetic resonance imaging demonstrated a mass with low signal intensity on T1-weighted images (WI) and high signal intensity on T2-WI. Resected specimens immunohistochemically showed positive results for alpha-smooth muscle actin, muscle-specific actin (HHF35) and vimentin, and negative results for S-100 protein, CD34, desmin, EMA, keratin, calretinin, HBME1, and c-kit.

Small bowel anisakiosis: a report of two cases.

Small bowel stenosis is a serious complication of intestinal anisakiosis. The aim of this report is to investigate whether severe stenosis of the small intestine can be conservatively managed. We treated two patients with severe stenosis of the small intestine caused by anisakiosis.
