This study was designed to evaluate pulse sequences and patient positioning for MR imaging of silicone breast implants in patients. One hundred forty-three patients (281 silicone implants) underwent imaging over a 21-month period. The combination of a T2-weighted fast spin echo technique (SE), T2-weighted fast SE with water suppression, and T1-weighted SE with fat suppression is recommended to reliably differentiate silicone from other breast tissues and to identify intracapsular and extracapsular ruptures or leaks. Seventy of the 143 patients underwent removal of their silicone implants. The sensitivity for detection of silicone implant rupture was 76%, with a specificity of 97%. Positioning the patient prone improved image quality

Hibernoma is an uncommon soft tissue tumor that is derived from the remnants of fetal brown fat. Review of the world medical literature revealed 90 cases, 6 of which were intrathoracic. We present the seventh case of intrathoracic hibernoma; in this case, the hibernoma was within the mediastinum without direct invasion of other structures.

A 35 year review of adenocarcinomas of the esophagus was undertaken. We found the disease to be one of increasing incidence afflicting white males disproportionately. Risk factors remain to be clarified. Radiation therapy in curative doses and complete resection were competitively effective in terms of long-term survival. No survival advantage was found with palliative surgery compared with other means of therapy. Optimal combinations of treatment remain to be discovered.
