Primary isolated echinococcal cyst of the seminal vesicle: a rare case

ABSTRACT

Hydatid disease of the organs other than liver and lung is extremely rare. Although hydatid disease is endemic in India, we report a rare case of hydatid cyst in a young male primarily involving the seminal vesicle and aim to highlight the management of such cases. A 23 year old male farmer diagnosed with primary isolated echinococcal cyst of the seminal vesicle has been presented. Thorough investigations with radiological methods such as ultrasonography [abdominal and trans-rectal], and magnetic resonance imaging were carried out to aid in the diagnosis. Surgical excision of the lesion was carried out with careful removal of the cyst to prevent any bursting and spillage, leaving the seminal vesicle preserved. The cystic lesion was subjected to histopathological examination. Histopathology confirmed the diagnosis of hydatid disease. Postoperative period was uncomplicated and patient was discharged on seventh postoperative day. Patient was put on albendazole [10 mg/kg/day] for three cycles of 21 days each with a gap of one week between each cycle. There was no evidence of recurrence or development of cysts elsewhere in the body during the 2 year follow-up. Hydatid cyst of seminal vesicle is rare and should be kept in differential diagnosis of a cystic lesion in pelvis especially in regions where hydatid disease is endemic. Proper surgical and medical management to avoid any recurrences, and a regular follow-up, are of utmost importance to detect any late complications such as local recurrence of the disease and development of hydatidosis at the primary sites
