Abstract
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.
