Diagnosis

Congenital Pseudocyst

Clinical Notes

Pathology – Pseudocyst formed by myofibroblastic tissue and smooth muscle suggestive of duplication cyst although no epithelial lining identified.

Findings

CT – Fluid attenuating left upper quadrant mass with few internal septations. The left kidney is small.

Discussion

Enteric duplication cysts can occur anywhere along the digestive tract on the mesenteric side. The small intestine is most commonly involved. Duplication cysts most commonly manifest during the first year of life, although some occasionally manifest in older patients. Children can present with a variety of symptoms including abdominal distention, vomiting, pain, bleeding, a palpable abdominal mass, and rarely urinary symptoms. Complications include perforation, intussusception, bowel obstruction from adjacent pressure or mass effect, volvulus, and associated malignancy. Duplication cysts can be associated with other congenital abnormalities, such as vertebral or urogenital malformations. The treatment of choice for enteric duplication cysts is surgical excision.
