摘要 Objectives: To discuss the bleeding mechanisms after removing a medulla oblongata hemangioblastoma. Methods: A 42-year-old male patient was diagnosed with a medulla oblongata hemangioblastoma. Preoperative cranial magnetic resonance imaging, computed tomography angiography and post-surgery computed tomography were completed during clinical procedure. We also reviewed the related literatures. Results: The preoperative computed tomography angiography did not demonstrate any intracranial aneurysm. But, the patient had a fatal subarachnoid hemorrhage with ventricular hemorrhage 4 hours after surgery following the post-surgery computed tomography. Conclusions: Subarachnoid hemorrhage after surgery of the medulla oblongata hemangioblastoma is very rare. Delayed postoperative hemorrhage seems the most reasonable explanation of Subarachnoid hemorrhage in our case.

20161117201304 Figure 1 (a, b) Preoperative contrast-enhanced magnetic resonance images revealed a cystic solid hemangioblastoma, which was located on the dorsal part of the medulla oblongata. (c, d) Preoperative computed tomography angiography (CTA) images revealed that the bilateral vertebral arteries, basilar artery, and bilateral posterior cerebral arteries were slender and the right posterior cerebral artery was stenotic. It also showed the relationship between the tumor and the feeding arteries. No aneurysm was seen on the CTA scans
20161117201323 Figure 2 The arrow on the intraoperative photograph is pointing to a large draining vein of the tumor, and the tumor margins were exposed completely in this operative field.
20161117201342 Figure 3 Histological examination showed round-to-oval nuclei and abundant clear cytoplasm in most cells, confirming a hemangioblastoma.
