Primary hydatid cyst of the psoas: report of 2 cases

ABSTRACT

We report two patients with hydatid cyst of the right psoas muscle who presented with lower back pain and a palpable mass on the right side. The diagnosis was confirmed by computed tomography [CT] in both patients and by positive hydatid serology in one case. Intervention consisted of a pericystectomy in both cases. After a follow-up of 24 and 30 months, respectively, the hydatid serology is negative in both patients and the findings on control CT are normal. Based on these two cases and a review of the literature the authors discuss the diagnosis and treatment of this rare entity
