Ovarian fibroma (fibrothecoma) with extensive cystic degeneration: unusual MR imaging findings in two cases.

Two cases of ovarian fibroma (fibrothecoma) with extensive cystic degeneration are described. One case revealed a large multiloculated cystic mass with a small solid part. Each locule showed variable signal intensity on both T1- and T2-weighted magnetic resonance (MR) images. The other case revealed a parviloculated cystic mass with a small solid part. In both cases, the solid parts were located at the periphery of the mass and showed distinct low signal intensity on both T1- and T2-weighted MR images and slight enhancement. It should be noted that ovarian fibromas (fibrothecomas) with extensive cystic degeneration are a rare exception to the rule that solid components in a cystic adnexal mass imply malignancy.

Noncardiogenic pulmonary edema as the first manifestation of pheochromocytoma: a case report.

We report here a case of pheochromocytoma presenting with noncardiogenic pulmonary edema, which is an unusual first manifestation of pheochromocytoma. Chest radiograph showed diffuse consolitaion and ground-glass opacity on both lungs. Neither pleural effusion nor cardiomegaly was present. High-resolution computed tomography (HRCT) showed widespread ground-glass opacity with fine intralobular reticular opacity (so-called "crazy-paving" appearance) and consolidation in a strikingly dependent distribution. The areas of ground-glass opacity and consolidation were sharply marginated by interlobular septa, showing a geographic appearance. The pulmonary edema and dyspnea resolved over three days without cardioactive or diuretic treatment. Noncardiogenic pulmonary edema is an unusual first manifestation of pheochromocytoma. It is important to recognize this unusual manifestation in the emergency situation.

Intermediate dose pre-operative irradiation for carcinoma of the rectum.

BACKGROUND: To assess the locoregional control, survival and toxicities of combined intermediate-dose pre-operative irradiation and surgery for rectal cancer patients. MATERIALS AND METHODS: Forty-two patients with adenocarcinoma of the rectum underwent intermediate-dose pre-operative radiotherapy. The median age was 58 years. the prescribed dose was 30.6 Gy to the whole pelvis, while a boost of 4 x 3 Gy to the primary tumor was added. The calculated linear-quadratic dose was 52 Gy. RESULTS: Failure as a first site was pelvic in 2 and distant in 11. The crude pelvic failure rate was 9.5%. The 3- and 5-year overall survival was 75% and 63%, respectively. Pre-operative radiotherapy was well-tolerated by all. No anastomotic breakdown was seen. Nor was any death attributable to any adverse effects of the treatment. CONCLUSION: The present results suggested that pre-operative intermediate-dose radiotherapy is effective in preventing pelvic recurrence in rectal cancer patients with acceptable toxicities.
