Mammography screening was carried out in 18012 women (aged 50-59) of whom 579 (3.21%) had to be recalled for clinical mammography. After completion of the clinical mammography each woman also had ultrasonography (US) with a hand-held real-time apparatus using a 7.5 MHz probe. There were 79 verified breast cancers; 32 of these were palpable and were also depicted at US, but only 29 (61.7%) of non-palpable breast cancers (n=47) were found at US. Twenty-two of the non-palpable breast cancers were seen at US as a tumor-like lesion, 2 because of local echo-architecture distortion, and 5 only because of acoustic shadowing. The US image did not help to differentiate between malignant and benign lesions.

A rare case of benign retroperitoneal schwannoma in a 76-year-old man is reported. Ultrasound and computerized tomography disclosed two cystic retroperitoneal tumors sized 12 cm and 7 cm. The larger tumor was located anterior to psoas muscle and the smaller one was within the muscle. The larger tumor was excised via laparotomy. After 3.5 years follow-up the intramuscular tumor has remained unchanged and the patient has no symptoms.
