The authors reviewed mammograms and/or ultrasound (US) scans of 76 lesions (67 patients) suspected of being recurrent breast cancer. All patients had previously undergone mastectomy. Sixty-one cases were malignant disease and 15 were benign. Mammography and US were complementary to clinical examination in evaluating palpable lesions at the mastectomy site. Both imaging methods revealed nonpalpable recurrences. The sensitivity of US was 91%, whereas the sensitivities of clinical examination and mammography were 79% and 45%, respectively. US was the best imaging method for evaluating tumors in the chest wall far from the scar and in the axilla, as these could not be visualized on mammograms. Most recurrent cancers were seen as circumscribed masses at mammography and as hypoechoic lesions at US. Hyperechoic recurrences could not be differentiated from benign lesions. The value of early detection of recurrences with imaging methods remains to be seen.

Adenomatoid tumors are regarded as uncommon neoplasms of the paratesticular tissues, probably of mesothelial origin. The majority of cases reported have involved the epididymis. We report our experience with 8 cases of testicular tumors and 11 of epididymal adenomatoid tumors during a 13-year period, and review the relevant literature. The incidence of adenomatoid tumors relative to all tumors in the testis was 6.9% (8 of 116), exceeding that of Leydig cell tumors, which were previously believed to be the most common benign testicular neoplasms. The adenomatoid tumors included 38% epididymal tumors (11 of 29). The clinical course of the tumors was benign, without recurrences. Local excision is regarded as the treatment of choice for epididymal and testicular adenomatoid tumors.

Sclerotherapy with 5% ethanolamine oleate was used to treat 102 hydroceles in 100 patients and 63 spermatoceles in 58 patients. Scrotal ultrasound examination was performed before the sclerotherapy and at each followup visit. Of the hydroceles 98% were cured completely and 68% were cured after only 1 sclerosant instillation, while 60% of the spermatoceles resolved completely and 33% partially, with 7% failures. No hydroceles recurred during an average followup of 43 months, whereas spermatocele recurred in 4 patients more than 1 year after successful treatment, with a mean followup of 46 months. Approximately half of the patients experienced pain after treatment, 3 had infection and 2 had hematoma. No changes in the structure or size of the testicles were found by ultrasound during followup. Ethanolamine oleate sclerotherapy is a safe, effective and economical form of outpatient therapy that can be recommended as primary treatment for hydroceles in adults and as an alternative to surgery for spermatoceles with 1 to 3 cysts in elderly men in whom fertility is not important.

Adenomatoid tumors are regarded as uncommon neoplasms of the paratesticular tissues, probably of mesothelial origin, and the majority of cases reported have involved the epididymis. Ultrasonography is the method of choice for imaging scrotal pathology, but there are very few data on ultrasound findings in cases of adenomatoid tumors. We report our experience and ultrasound findings regarding 8 intrascrotal adenomatoid tumors--3 cases of a testicular tunica albuginea tumor and 5 cases of epididymal origin. Ultrasonography is recommended as the preoperative imaging method for excluding the possibility of a cystic lesion and for determining the location of the tumor. Local excision is regarded as the treatment of choice. The clinical course of all these tumors was benign, without recurrences.

The results of 102 preoperative ultrasonographically guided wire localizations of nonpalpable breast lesions were reviewed. Ultrasonography was used because of nonvisualization during mammography (16 cases), a difficult location of the lesion (3 cases), vasovagal syncope during mammographic guidance (two cases), or the radiologist's preference (81 cases). All localizations were successful. Removal was confirmed by specimen mammography or ultrasonography or both in 85 cases and by macroscopic examination in 10 cases. In seven cases specimen radiography was not performed. One syncope and one wire insertion into the pectoralis fascia occurred. Ultrasonographically guided wire localization is accurate and well tolerated in aiding surgical biopsy of breast lesions.

Five anterior mediastinal tumors were biopsied with a fine needle under ultrasound guidance. All the tumors were solid, hypoechoic, perivascularly situated masses. Their mean diameter was 7.2 cm. Cytologically there were 2 mediastinal metastatic carcinomas, 1 poorly differentiated carcinoma or non-Hodgkin lymphoma, 1 germ-cell tumor (embryonal cell carcinoma), and 1 malignant lymphoma or thymoma. There were no complications. Ultrasound-guided anterior mediastinal aspiration biopsy is a safe and rapid procedure in the evaluation of anterior mediastinal masses. Biopsy of a mediastinal mass enables simultaneous diagnosis and staging. Mediastinoscopy and diagnostic thoracotomy can be avoided.
