ABSTRACT
The authors compared color-Doppler US with angiographic findings in the study of peripheral lower limbs aneurysms. Twelve cases were observed over a 2-year period of time. In each case, the combination of B-mode and color-Doppler US permitted the accurate evaluation of the aneurysm and of the possible compression of adjacent vessels. Angiography, which was considered the gold standard, detected only 8 of 12 cases; in 3 of 8 cases, the actual diameter of the aneurysm was under estimated. The simultaneous visualization of vessel wall and of intraluminal blood flow proved color-Doppler US to be superior to the gold standard in these cases. The authors conclude that color-Doppler US may become the new reference standard in the diagnosis and follow-up of peripheral aneurysms.

Tropical splenomegaly is a pathologic condition due to multiple causes, endemic malaria being the major one. Twenty-eight black patients, 10 males and 18 females, residing in a tropical area, were investigated with US. The morphological features and major diameters of the spleen were studied and the splenic volumetric index (IVS) was calculated. Typical features were the presence of small intraparenchymal calcifications (46%) and the enlargement of splenic vessels, with US wall reinforcement (75%). No nodular lesions were detected, but increased frequency of organ lobulation was observed. A definite and uniform increase in splenic diameters was seen in all cases; IVS in particular was greater than the accepted confidence limit (21.5 +/- 6.5). This characteristic features should help the echographist to recognize this condition for they supply useful clinical information.

The present work is the result of a multicentric study performed at Hoima and Kitgum Hospitals in Uganda on a group of 20 children with Kwashiorkor. Bone age was evaluated on the X-ray film of the children's left hand and wrist, according to Tanner and to De Roo, by 2 different evaluators. The final results were compared. Eighty-five % of the patients presented delayed bone maturation: such a result confirms the importance of malnutrition on skeletal development. The data reported by other authors are also discussed.

The authors discuss the results from a series of 45 patients with breast lumps. All patients were studied by means of mammography, sonography, color Doppler US, and biopsy. Abnormal Doppler signal was observed in 94% of the patients with breast cancer. However, this finding is not specific because it can be occasionally found in benign lesions too. The use of color Doppler US is suggested in those cases where neither US nor mammography is conclusive.

Color Doppler and Duplex Doppler US were employed on 4 patients with clinically suspected pseudoaneurysms as a complication of femoral artery puncture after cardiac catheterization. Pseudoaneurysms were identified with Color Doppler US and their typical appearance was confirmed. The grey-scale findings did not allow an adequate differentiation between hematoma and pulsed hematoma without fibrous encapsulation: only Color Doppler US easily detected the track between damaged artery and blood collection and allowed a sample to be obtained for pulsed Doppler examination. Color Doppler US allowed an accurate and non-invasive diagnosis of groin masses after femoral artery catheterization.

The role of sonography is evaluated in the diagnosis of ovarian tumors. Real-time US proves more sensitive than gynecological examination in the diagnosis of ovarian diseases. As yet, however, no correlation has been found between histological findings and US appearance. An accurate review of the relative literature and of our results lead us to the conclusion that sonography does not significantly affect the early diagnosis of ovarian tumors.
