Remote cerebellar hemorrhage following resection of a supratentorial tumor: a case report

Remote cerebellar hemorrhage after supratentorial surgery is rare, ranging between 0.08% and 0.29% in adults and children. However, it is extremely rare in children. This phenomenon underlying mechanisms remain obscure. A 14-year-old male child patient had a history of right focal seizures and underwent craniotomy for a left frontal mass (Dysembryoplastic Neuroepithelial Tumor). First hours post recovery period, the patient was somnolent and had right hemiparesis. Postoperative Computer Tomography and magnetic resonance imaging findings revealed that the patient had developed remote cerebellar hemorrhage. He was treated conservatively, and was free of neurological deficits. Although dehydration and the displacement of the cerebellum are associated with this phenomenon after supratentorial surgery, the identification of the exact etiological factors remains elusive. It is advisable for case givers to be aware of the high potential risk of morbidity and mortality of this entity. Preoperative attention to prevent cerebrospinal fluid overflow leakage and exaggerated dehydration of the patient may prevent remote cerebellar hemorrhages.
