Abstract
Remote cerebellar hemorrhages (RCHs) are rare complications of intracranial or spinal interventions. We describe a patient with an RCH that occurred after a frontal lobectomy for an intracranial tumor. A 41-year-old female patient with a headache and partial seizures underwent a right frontal lobectomy upon detection of a right frontal mass. An RCH (zebra sign) was detected on a control cranial computed tomography (CT), which was performed upon detection of frontal lobe syndrome and mild ataxia in the patient postoperatively. Although the mechanism underlying the occurrence of RCHs after intracranial procedures is not clear, they have been attributed to an imbalance between intravascular pressure and cerebrospinal fluid (CSF) due to rapid drainage of the fluid, causing bleeding in the cerebellar parenchyma. Generally, bilateral superior cerebellar injury produces parallel flat hyperdense areas known as the zebra sign on CT. The prognosis of a cerebellar hemorrhage is generally good, and it can be treated with a conservative approach. Controlled drainage of CSF during surgery and selecting an appropriate surgical position perioperatively will reduce the risk of RCHs.

(2014) Remote Cerebellar Hemorrhage after Frontal Lobectomy: Zebra Sign. The so-called zebra sign is usually seen after supratentorial vascular interventions or temporal lobe resections. It is common after routine computed tomography (CT) [1] [7][16]. The seizures had abrupt onset and termination, and they usually occurred at night, causing the patient to shout out. They caused oral paralysis, tonic contractions in the upper limbs, and headaches, which had begun 8 months earlier and gradually increased. Pathology examination results revealed a malignant glial mass, and the patient was transferred to an oncology clinic
