Subarachnoid hemorrhage is one of the most important and dangerous neurologic emergencies worldwide. It is characterized by a sudden and severe headache caused most commonly by the rupture of intracranial aneurysm. Cerebral vasospasm is the most important cause of disability and death in whom survived from the first event. Early diagnosis and management of cerebral vasospasm could prevent and reduce its morbidity and mortality. Thus, an ideal technique must be able to detect the vasospasm before the occurrence of neurological deficits. Perfusion computed tomography could assess vascularity of brain including cerebral blood flow, cerebral blood volume, time to peak and mean transit time. For this application, perfusion computed tomography and computed tomography angiography techniques offer significant advantages and can result in early diagnosis of vasospasm. In this review, we discuss the utility of these two techniques and their safety in the diagnosis and the management of vasospasm following subarachnoid hemorrhage.

Background & Importance: Acute epidural hematoma is a very rare complication of ventriculoperitoneal shunt insertion. The insertion of a ventriculoperitoneal shunt can cause sudden decompression of the brain, subsequent to which epidural hematoma occurs due to CSF drainage. To our knowledge, there are only a few cases of acute epidural hematoma in the literature which required acute evacuation.Case Presentation: In this report, we present a case of epidural hematoma close to ventriculoperitoneral shunt insertion site in a 30–year–old man after failure of endoscopic surgery for opening of the wall of a suprasellar arachnoid cyst. Secondary to communication between cyst and ventricles and clinical symptoms and sings, the patient underwent the shunt insertion. The patient became comatose two hours following the insertion of the shunt, developing a voluminous right temporo–parietal epidural hematoma that had to be evacuated immediately. Here, we intend to discuss both the pathophysiology and treatment.Conclusion: Development of epidural hematoma after ventriculoperitoneal shunt surgery is a devastating complication. Dehisensce formation between the skull and dura matter, which may be facilitated by lax adhesion between the two, is a common underlying pathology. We recommend a close post–surgical observation for immediate diagnosis and reoperation of this event.
