277 patients underwent biplane transrectal ultrasonography. Twenty-two
patients (7.9%) showed evidence of one or more intraprostatic cystic
lesions. Histologic correlation was available with total prostatectomy
specimens in six patients and surgical drainage in two patients.
Sonographically, 11 patients showed one, 6 patients two, and 5 patients
three or more intraprostatic cystic lesions. The size of the lesions ranged
from 2 to 30 mm, and the majority of lesions were located within the
central portion of the gland or at the junction of central and peripheral
regions of the gland. Histologically, among the eight pathologically
confirmed patients the lesions corresponded to cystically dilated,
epitheliallined prostatic glands, a reepithelialized cyst related to
previous biopsy, a dilated utricle, and two intraprostatic abscesses. The
cystic lesions in our series were not associated with carcinoma of the
prostate, but represented either a growth phenomenon related to the
presence of benign prostatic hypertrophy, inflammatory conditions
(abscesses), or anatomical variants (utricle).
