Summary
This case report details a rare non-pancreatic pseudocyst in a 35-year-old male. Surgical removal was successful, highlighting the need to consider these rare lesions in abdominal cystic masses.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Abdominal Imaging
Background:
- Non-pancreatic pseudocysts are rare abdominal lesions originating from the omentum or mesentery.
- These cysts feature thick, fibrotic walls, potential calcifications, and variable internal fluid content.
- Etiologies include trauma, surgery, or infection, but origins can be unknown.
Observation:
- A 35-year-old male presented with a 2-year history of gradually enlarging lower abdominal swelling.
- Imaging revealed a large (16x12x10 cm) cystic peritoneal lesion with a thick wall and septa, and an 8x6 cm soft tissue component.
- The patient experienced urinary symptoms, and the mass became painful prior to presentation.
Findings:
- Surgical excision of the cystic mass was performed, involving partial resection of the bladder wall.
- Histological examination confirmed a non-pancreatic pseudocyst, a rare diagnosis.
- The patient recovered well post-surgery.
Implications:
- Primary non-pancreatic pseudocysts are rare and require differentiation from other cystic pathologies.
- Awareness of these entities is crucial for surgeons encountering unusual peritoneal or retroperitoneal cystic lesions.
- This case underscores the importance of considering rare diagnoses in clinical practice.
