Giant peritoneal loose body - case report.

Area of Science:

• Gastroenterology
• Radiology
• Pathology

Background:

• Intra-abdominal masses can present diagnostic challenges.
• Giant peritoneal loose bodies are rare, benign entities.
• Distinguishing benign from neoplastic masses is crucial for patient management.

Observation:

• A patient presented with an incidentally detected left hypogastrium mass with calcification on CT angiography.
• The mass showed significant mobility on subsequent PET/CT, raising suspicion for a teratoma.
• Exploratory laparotomy revealed a freely mobile, avascular ovoid mass.

Findings:

• Histopathological examination confirmed the mass as a giant peritoneal loose body.
• This benign pseudotumor was not connected to any other structures.
• The lesion was asymptomatic and incidentally discovered.

Implications:

• Giant peritoneal loose bodies should be considered in the differential diagnosis of mobile intra-abdominal lesions.
• Asymptomatic cases may be managed conservatively, avoiding unnecessary surgical intervention.
• Accurate radiological and pathological assessment is key to appropriate diagnosis and treatment planning.
