Focal, asymptomatic epididymal masses--B-mode and color Doppler sonographic evaluation. Case report.

We reported the case of an adult male with an extratesticular mass prove to be postoperative a chronic inflammatory process. The importance of B-mode and color Doppler sonography in the differential diagnosis and literature regarding epididymal nodules and tumors of the paratesticular structures (epididymis) is reviewed and discussed.

Focal hepatic lesion ultrasound-guided biopsies.

PURPOSE: To compare the results of pathologic and cytologic reports of specimens acquired from focal liver lesions using ultrasound-guided biopsy and to evaluate the necessity of performing both techniques in the same patient. MATERIALS AND METHODS: 21 patients were eligible for enrollment in the study. Specimens for both pathologic and cytologic examination were obtained from 16 lesions using a 17G needle guide in a single puncture attempt. In 2 cases the diagnosis was based on cytologic smears. In 3 cases only histologic sections were acquired. The needle was introduced under continuous ultrasonographic control using a freehand technique. A cytologist was present at all times. RESULTS: The diagnostic sensitivity of cytologic examination was 83.33% and that of histologic examination was 94.74%. Histology diagnosed all cases of benign lesions and was proved inconclusive in 1 patient. The diagnostic sensitivity and accuracy of both methods combined reached 100%. In 94.4% malignancy was immediately diagnosed by cytology. CONCLUSIONS: Combination of both methods should increase the sensitivity and accuracy in diagnosing focal liver lesions performing a safe minimally invasive technique.

Sister Mary Joseph's nodule: Three case reports.

BACKGROUND: An umbilical metastatic lesion is called 'Sister Mary Joseph's nodule'. It is an uncommon clinical or radiographic finding, and it is rare as the first sign of a malignant disease. CASE PRESENTATION: We report three cases of Sister Mary Joseph's nodule. In the three cases presented, the primary tumor was an adenocarcinona of the sigmoid colon, a carcinoma of the bladder, and an adenocarcinoma of the gallbladder, respectively. CONCLUSION: The differential diagnosis of an umbilical lesion should always include metastatic disease apart from benign lesions and primary neoplasms.

Rigler sign: an underappreciated alert for pneumoperitoneum.

A patient presented with abdominal pain. Supine abdominal radiograph disclosed free intraperitoneal air (Rigler sign). This finding prompted further work-up and treatment.
