pelvic hydatid cyst presenting with lower limb edema

ABSTRACT

Hydatid disease is an infection caused by larval stage of Echinococcus granulosus in humans, which are carried as tapeworms by canines. The most frequent organs affected in humans are liver and lungs. We presented a case of pelvic hydatic cyst which is a rare occurrence. There was a 75 years old man with a history of admission for left lower limb edema suspected to DVT. The patient was suffering from generalized abdominal pains especially in LLQ. On pelvic ultrasound and CT scan, a cystic mass with internal septation on the left side of pelvis was reported. After surgery, pathology report of removed cyst confirmed the hydatid cyst. In endemic regions, in patients complaining of lower limb edema and suspected to have DVT, pelvic mass lesions such as hydatic cyst should be born in mind
