Abstract
BACKGROUND: Bronchogenic cyst is a rare congenital developmental abnormality of the anterior bowel. Peri-pancreatic bronchogenic cyst (PBC) is extremely rare, when only a few cases reported worldwide. Diagnosis of PBC is difficult due to the lack of specific clinical features and symptoms, laboratory and imaging findings. Currently, the diagnosis of PBC mainly relies on the comprehensive judgment of multidisciplinary collaboration, combined with clinical manifestations, imaging features and pathological verification. Most bronchogenic cysts are benign and the long-term survival rate after complete resection is close to 100%. CASE PRESENTATION: A 21-year-old male with a pancreatic mass was admitted to our hospital. CT scan showed a low-density cystic shadow about 3.6 × 3.5 cm(2) on the pancreatic body, with clear boundaries, no enhancement, and no dilation of the main pancreatic duct. The patient underwent open distal pancreatectomy. Postoperative histopathological findings allowed for a definitive diagnosis of PBC. There was no recurrence for two years postoperatively. CONCLUSION: In this study, we reported a rare case of PBC. At present, radical surgical resection remains the most effective treatment for bronchogenic cyst with mass effects, infection, bleeding, rupture, or larger than 3 cm in diameter. Further research on the diagnosis and treatment strategies of PBC is required.
