INTRODUCTION: Paraovarian cyst
arise from the mesothelium and presume to be vestigeal remnant of mullerian and wolffian duct.
DISCUSSION: The clinical presentation in the case reported here can mimic an infected paraovarian cyst
, hydrosalphinx, pyosalphinx, endometrioma, cystic ovarian neoplasm, macrocystic lymphatic malformations, pseudomyxoma peritonii or omental cysts.
Diagnosis of torsion paraovarian cyst
was made and patient was posted for emergency laparotomy.
are benign lesions that arise from wolffian duct remnants and are usually seen along the broad ligament.
Extragonadal occurrence is observed primarily in the sacrococcygeal region, mediastinum, retroperitoneal cavity, cranial cavity or in the neck area (3, 4), Paraovarian cysts
are presumed to come in the remnants of mullerian duct (3).
Common types are cystic teratomas, paraovarian cysts
, serous cystadenomas (1).
