An unusual presentation of an idiopathic omental pseudocyst: A case report and literature review

Background: Idiopathic omental pseudocysts occur very rarely in adults. Pseudocyst patients usually have a history of either trauma (e.g. seat belt injuries) or other related intra-abdominal pathology (e.g. pancreatitis, malignancy). They may result in a range of complications, from frequent abdominal pains with inconclusive diagnosis mimicking acute appendicitis, acute cholecystitis, or twisted ovarian cysts, to intestinal obstruction and peritonitis. Case Report: A rare case of omental pseudocyst presenting as all acute intestinal obstruction in a 64-year-old woman without any previous history of significant abdominal pain, relevant medical problems, or trauma is reported. Oil plain abdominal x-ray, tile cyst with dystrophic calcifications appeared as a dermoid cyst with multiple teeth. The optimal diagnostic methods, such as CT scanning and ultra-sound imaging, which may show a well-circumscribed soft tissue mass are discussed. Uncomplicated and stable patients with established diagnosis call be treated conservatively. Surgical management includes resection of the cyst by either laparoscopy or laparotomy. Conclusions: Prognosis is good since omental cysts shows no documented tendency for malignant degeneration or recurrence. Optimal Surgical management requires complete excision of these lesions.
