It is common to find brain profusion changes after head injury or other cerebrum events. Among them, Crossed Cerebellar Diaschisis (CCD) might affect patients’ long-term prognosis. Ipsilateral Cerebellar Diaschisis (ICD) revealed lower incidence with unknown effects for recovery. Both can be detected by brain perfusion scintigraphy. In this article, we present the case of a 50-year-old male with headache attack months ago. Intraparenchymal hemorrhage of brain was diagnosed with a right ruptured aneurysm. Poor improvement of left side hemiplegia after operation, we arranged brain perfusion scan for further evaluation. Images disclosed hypoperfusion in right frontal lobe and bilateral cerebellum area. There were no studies about CCD and ICD occurred at the same time. We speculated that ICD as well as CCD can affect the patient long-term motor outcomes compared with those without phenomenon of ICD.
