Although the exact timing depends on the location of the traumatic brain injury (TBI) and the amount of hemorrhage, in the absence of neurosurgical interventions it usually takes several weeks or months for spontaneous resolution of the hemorrhage or hematoma. The occasional rapid disappearance of an intracranial hemorrhage after a TBI has been well-described in the literature. However, early spontaneous disappearance of traumatic intraventricular hemorrhage (TIVH) has not previously been reported in the literature. Herein, the author described a rare case of TIVH that disappeared rapidly without surgical intervention and speculated that the thrombolytic enzyme system in the cerebrospinal fluid (CSF) or circulation of CSF plays an important role in the rapid disappearance of TIVH.
