Mumps epididymo-orchitis: sonography and color Doppler sonographic findings.

Eleven cases of mumps epididymo-orchitis were examined by gray-scale and color Doppler ultrasonography. Nine cases were unilateral and two were bilateral. In the initial examination, the volume and the vascularity of the affected testis and epididymis and the thickness of the scrotal wall was greater than of the normal site, whereas the testicular echogenicity was decreased homogenously, resistivity indexes of intratesticular arteries were decreased, and spontaneous venous flow was seen in all cases. In contrast to nonspecific epididymo-orchitis, no hydrocele was seen, but minimal reactive hydrocele was found in two cases. The diagnosis was confirmed by specific immunoglobulin-G examination. Patients were given interferon and were controlled by ultrasonography and Doppler ultrasonography at the third and seventh days of treatment and 3 months after treatment. Sonographic findings began to improve by the third day and fully disappeared in seventh day. No testicular atrophy was seen in the last control. To our knowledge, this is the first report on sonographic and color Doppler sonographic findings of mumps epididymo-orchitis.

Cerebral hydatid cysts: CT findings.

The CT features of cerebral hydatid cysts are divided into two groups. In the unilocular cases, the cyst is large, spherical in shape with sharply defined borders. One side of the cyst wall is very close to the calvarium. The cyst may calcify and may have septae inside. There is no enhancement with contrast media and also no edema surrounding the cyst. In the second group there are multiple and small multilocular cysts. These cysts are in ovoid or polygonal forms like a bunch of grapes, with perifocal edema. After contrast media administration, there is enhancement in the cyst wall. In one case there were numerous cysts in both hemispheres.
