Intraperitoneal chronic expanding hematoma mimicking an ovarian tumor: A case report

Chronic expanding hematoma of soft tissue is a rare lesion and often misdiagnosed as neoplastic mass. It is mostly related to trauma or surgery, leading to blood-filled cysts surrounded by fibrous tissues. Symptoms may include abdominal pain, nausea or bowel obstruction. Diagnosis is often difficult, and imaging tests such as CT scans or MRIs can be inconclusive. Treatment may require complete surgical removal to prevent postoperative recurrence. We present a case of a 27-year-old woman with history of recent abdominal trauma presented with an abdominal mass, along with chronic pain and vomiting. CT scan revealed a large pelvic cystic mass, suggesting an ovarian origin which was ruled out by the MRI. Surgery was performed and histopathology revealed an intraperitoneal chronic expanding hematoma. In this case report, we review the epidemiological, clinical, and paraclinical aspects of the disease, as well as the treatment modalities.
