RESUMO
We report on a patient who presented a fibrovascular polyp of the esophagus, which is an uncommon submucosal tumor that can attain giant proportions. It is covered with squamous epithelium and consists of a mixture of myxoid-collagenous fibrous elements, vascular structures and adipose cells. Diagnosis is made via upper endoscopy, echoendosonography and barium studies. CT and MR imaging can be helpful for full evaluation of this rare lesion.

We report on a case of complicated long-term amiodarone therapy. CT demonstrated high attenuation pleural-parenchymal lesions and increased liver and spleen density. This article stresses the important role of CT in the diagnosis of amiodarone related disease.

PURPOSE: To describe a benign nodular lesion in the peripheral zone (PZ) of the prostate gland. MATERIALS AND METHODS: In 1,087 patients, the features of 722 focal lesions in the PZ or central zone of the prostate on transrectal ultrasound (TRUS) scans were retrospectively compared with histologic findings in biopsy samples. RESULTS: In 18 patients (5.5% of the 328 patients with benign lesions), benign hyperplasia was found in a focal, nodular lesion obviously located within the PZ. On TRUS scans, the nodules were well circumscribed, ovoid or round, and slightly hypoechoic (n = 11) or isoechoic (n = 7). The isoechoic lesions were surrounded by an anechoic halo. One nodule was an incidental sonographic finding; the 17 others were felt as firm (n = 11) or soft (n = 6) at digital rectal examination. The ratio of serum prostate-specific antigen (PSA) level to prostatic volume was low (< 0.1), except in one patient (0.24). CONCLUSION: Some sonographic features and the normal PSA values might suggest a benign nodule in the PZ, but TRUS-guided biopsies and histologic correlation are necessary to confirm the diagnosis.
