A 46-year-old women was examined for severe constipation. Pelvic examination revealed a large pelvic mass extending to the level of the umbilicus. Computed tomography showed a large multicystic, septated mass in the pelvis and a small amount of fluid in the cul de sac. In addition, multiple ill-defined, mixed-attenuation hepatic lesions were identified. A malignant ovarian neoplasm with liver metastases was considered, so the pelvic mass was resected. Interestingly, histopathologic analysis revealed malignant struma ovarii of the follicular type. Biopsy of the liver lesions confirmed metastatic disease with similar histopathologic findings. All thyroid laboratory values were in the normal range. The patient then had a total thyroidectomy to optimize thyroid ablation therapy with I-131. This revealed a small follicular adenoma but no evidence of cancer. An I-131 whole-body scan was performed and showed uptake in multiple functioning liver metastases.

Can tamoxifen cause a significant mammographic density change in breast parenchyma?
Aged; Antineoplastic Agents; Breast Neoplasms/*diagnostic imaging/*prevention & control/surgery; Breast/anatomy & histology/*drug effects; Computer-Assisted; Female; Hormonal/*pharmacology; Humans; Image Processing; Mammography; Tamoxifen/*pharmacology
To evaluate tamoxifen-induced glandular tissue density changes in women who are on an adjuvant tamoxifen therapy. We examined serial mammograms of 27 women (average age 67) who had surgery for unilateral breast carcinoma and were on tamoxifen for 5 years. Mammograms obtained at the beginning of treatment, within 2 or 3 years, at the end of 5 years and 1 year after cessation of tamoxifen treatment, were evaluated by two radiologists experienced in reading mammograms. Four 1-cm-diameter circular areas of the glandular tissue and retroglandular fat were sampled by a densitometer and a relative glandular density (glandular tissue/fat density) was used for comparison between serial mammograms. Most cases (79%) did not show tamoxifen-induced change in glandular density. Three patients (13%) showed an early and two (8%) a delayed mild reduction in glandular density as compared to baseline mammograms. No patient was found to have increased glandular density following the cessation of tamoxifen therapy (in subjective evaluation). Densitometer readings showed a mild reduction in glandular densities in 16 cases (60%) during treatment and a minimal increase in 13 cases (48%) following cessation of treatment. There was a slight decrease in breast density during treatment [relative density of 0.012+/-0.006 (standard error) per interval, P value:.06] and the difference between years 5 and 6 was nearly zero [relative density of 0.00042+/-0.01 (standard error), P value:.97]. Long-term use of tamoxifen may cause a mild reduction in breast glandular density, although this, in part, may be attributed to the age-related mammographic density change. Following cessation of tamoxifen, no significant increase in glandular density was observed. Therefore, any increase in mammographic density during or after tamoxifen treatment should be viewed with suspicion and further evaluated.

Mesenchymal hamartoma of the liver.

We present a multiseptated mesenchymal hamartoma of the liver in a 10-year-old male patient, a rare benign tumor of childhood. The characteristic ultrasound and CT appearances of this unusual tumor are reviewed. A single septal calcification associated with this tumor was demonstrated, an association which has not previously been reported. The differential diagnosis for cystic liver lesions is discussed in detail.

Adenocarcinoma arising in interposed colon: report of a case.

A rare occurrence of primary adenocarcinoma arising in an interposed colon nearly seven years after the surgery is described. Remarkably, there were no symptoms from a large mass in the transposed bowel. Diagnosis was made fortuitously while searching for the cause of the patient's iron-deficiency anemia. The rationale for careful preoperative screening of the colonic segment intended for transplant to exclude pre-existing pathology is reemphasized. The various methods of evaluating the postoperative colon graft and their advantages and limitations are discussed.

Sonographic appearance of the Angelchik prosthesis.

The Angelchik prosthesis is a silicone-filled, doughnut-shaped device used for the surgical treatment of gastroesophageal reflux. This device appears on sonograms as a C-shaped, hypoechoic structure with nonspecific Doppler waveforms. Because the Angelchik prosthesis is rarely used anymore, recently trained sonographers and radiologists may misinterpret this sonolucent appearance as an unusual vascular lesion. We report a case of an Angelchik prosthesis that was incidentally noted at the gastroesophageal junction on a routine abdominal sonographic examination.
