Pelvic Hydatidosis Mimicking a Malignant Multicystic Ovarian Tumor

Abstract

Echinococcosis is a multisystem disease and has propensity to involve any organ, an unusual anatomical site, and can mimic any disease process. Primary peritoneal echinococcosis is known to occur secondary to hepatic involvement but occasional cases of primary peritoneal hydatid disease including pelvic involvement have also been reported. We report here 1 such case of primary pelvic hydatidosis mimicking a malignant multicystic ovarian tumor where there was no evidence of involvement of the liver or spleen. Our patient, a 27-year-old female, was detected to have a large right cystic adnexal mass on per vaginal examination which was confirmed by ultrasonography. Her biochemical parameters were normal and CA-125 levels, though mildly raised, were below the cut off point. She underwent surgery and on exploratory laparotomy, another cystic mass was found attached to the mesentery of the small gut. The resected cysts were processed histopathologically. On cut sections both large cysts revealed numerous daughter cysts. Microscopic examination of fluid from the cysts revealed free scolices with hooklets and the cyst wall had a typical laminated membrane with inner germinal layer containing degenerated protoplasmic mass. The diagnosis of pelvic hydatid disease was confirmed and patient was managed accordingly. Hydatid disease must be considered while making the differential diagnosis of pelvic cystic masses, especially in endemic areas.

Laparoscopic Treatment of Primary Mesenteric Hydatid Cyst

“…In our case, there was no other organ involvement and accepted primary mesenteric cyst hydatid. Hydatid cyst without complication are usually asymptomatic [4,6] . Mesenteric hydatid cyst is a non-specific mass and can cause abdominal pain due to pressure and traction to other adjacent organs.…”

“…Intraperitoneal hydatid cyst usually develops in relation to liver hydatid cyst rupture [3] . Primary mesenteric hydatid cyst is rare and diagnoses incidentally [3,4] . In the PubMed search, so far 7 cases were reported [3][4][5][6][7][8][9] .…”

“…Primary mesenteric hydatid cyst is rare and diagnoses incidentally [3,4] . In the PubMed search, so far 7 cases were reported [3][4][5][6][7][8][9] . We aimed to present a case of primary mesenteric hydatid cysts treated laparoscopically.…”

Tumeur kystique rétrorectale

“…D'autres diagnostics peuvent simuler le kyste hydatique rétrorectal, en particulier chez la femme, notamment le kyste de l'ovaire ou l'hydrosalpinx en cas de kyste hydatique pelvien univésiculaire, voire même un fibrome utérin ou une tumeur de l'ovaire en cas d'un kyste hydatique pseudotumoral [7,8].…”

Emerging and Re-Emerging Parasitic Zoonoses in India

“…Hydatid disease in human beings mainly involves liver (75 per cent) and lungs (15 per cent). Numerous reports (Eckert et al, 2001) exist on the occurrence of human hydatidosis in almost all states of the country viz., Tamil Nadu (Vamsy et al, 1991), Chandigarh (Kanwar et al, 1992;Khurana et al, 2007;Rathod et al, 2011), Kashmir (Chishti and Ahanger, 1998), Delhi (Gupta et al, 2002), Uttar Pradesh (Pandey et al, 2007;Kumar and Hasan, 2008), Kolkata (Acharya and Gupta, 2009), Pune (Singh et al, 2010a), Haryana (Sing et al, 2010), Kerala (Anoop and Jabbar, 2010), Karnataka (Umesh et al, 2010), Maharashtra (Akther et al, 2011), West Bengal (Pathak et al, 2011), Andhra Pradesh (Faheem et al, 2013 and New Delhi (Kayal and Hussain, 2014). Akther et al (2011) observed that the disease is common among house wives who have the practice of rearing sheep and goat.…”
