摘　　要：BACKGROUND Pancreatic cavernous hemangioma(pCH)is a rare type of benign vascular tumor.Making the right diagnosis is challenging due to low clinical suspicion and the lack of existing cross-sectional imaging tools to distinguish it from other pancreatic lesions.CASE SUMMARY We describe a male patient,age 18,who presented with a pCH.Computed tomography,magnetic resonance imaging,and ultrasound showed cystic space in the tail of the pancreas.A dark spot sign on the T2 weighted image sequence was observed.Clinically,a mucinous cystic neoplasm with hemorrhage was suspected preoperatively by combining imaging,and the operative indication was clear.The patient underwent a distal pancreatic tumor resection under laparoscopic control.Immunohistochemical staining for CD31 and CD34 was positive;D2-40 was positive in interstitial lymphatic vessels and negative in vascular epithelial cells;and calcium-binding protein was negative.The results support the diagnosis of pCH combined with chronic intracapsular spontaneous hemorrhage.No complications or recurrences were observed during the follow-up period.CONCLUSION Chronic spontaneous hemorrhage may occur in pCH,which may greatly influence the accuracy of diagnosis using imaging modalities.Surgical resection for uncertain pCH seems reasonable with a good outcome.
