Acute cerebellar hemorrhage Redemonstration of large cerebellar hemorrhage with mass effect against for centrical weight ventricular enlargement.The degree of ventricular enlargement comparing to prior CT scan does not show any significant interval change. However, there are evidence of intraventricular hemorrhage especially on bilateral lateral ventricle occipital horns, indicating extension of hemorrhage into the ventricular system.There are linear and nodular areas of the restricted diffusion especially inferior vermis and cerebellar sulci indicating the possibility of hemorrhagic transformation from underlying ischemic infarct.There is no evidence of abnormal enhancement on the scan.Multifocal scattered small susceptibility lesions on gradient echo images on bilateral hemisphere and brainstem indicate chronic petechial hemorrhage.The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Extension of hemorrhages into the ventricular system which is now more evidence comparing to prior scan. No change of ventricle size.2. The size and mass effect of right cerebellar ICH do not show significant interval change.3. Subtle restriction diffusion areas within the hemorrhage may provide clue for the possibility of hemorrhagic transformation from ischemic infarction.4. No evidence of abnormal enhancement.
