Background: Polycythemia vera (PV) is a myeloproliferative disorder usually characterized by an increase tendency toward thromboembolic events. Spontaneous hemorrhage/bleeding in PV patients is seldom reported in neurosurgical literature.
Case description: We report the case of a 76-year-old male with PV who developed a spontaneous subdural hematoma requiring surgical evacuation. He improved significantly after the resolution of brain compression and mass effect caused by the hematoma.
Conclusions: Sporadic reports of hemorrhage within the central nervous system in the setting of PV exist and are attributed to microvascular thrombotic events with hemorrhagic conversion. Though rare, spontaneous central nervous system hemorrhage in the absence of vascular malformation or an inciting event such as trauma can occur in the setting of myeloproliferative disorders like PV.
