A rare retrovesical hydatid cyst and value of transrectal ultrasonography in diagnosis: a case report and review of the literature

Abstract

We present a large hydatid cyst located midline and posterior to prostatic gland and seminal vesicles in an asymptomatic patient. Computed tomography (CT) scan revealed a large retrovesical mass and the transrectal ultrasonography idetified a degenerated hydatid cyst with “ball of wool’’ appearance. Although extremely rare, hydatid disease should be kept in mind in the differential diagnosis of pelvic particularly retrovesical midline masses.

Raman spectroscopy for rapid and inexpensive diagnosis of echinococcosis using the adaptive iteratively reweighted penalized least squares-Kennard–stone-back propagation neural network

“…Early diagnosis and intervention of echinococcosis is an effective approach to reduce its morbidity and mortality. At present, conventional examination methods include clinical symptom diagnosis, medical imaging technology diagnosis and immunologic diagnosis [3][4][5]. However, they have some problems; such as expensive instruments, cumbersome processes, technical person operation requirements and so on [6].…”
