Subarachnoid Hemorrhage*

Motor weakness is one of the neurological complication that can occur after aneurysmal subarachnoid hemorrhage (SAH); incidence of motor weakness of 14~29% has been reported. Detailed information on the pathogenic mechanism of motor weakness is essential for brain rehabilitation because it enables estimation of the severity of injury, establishment of scientific rehabilitative strategies, and prediction of motor outcomes by clinicians. However, the exact pathogenic mechanisms of motor weakness following aneurysmal SAH have not been clearly elucidated. In this article, 14 previous studies on pathogenic mechanisms in patients with aneurysmal SAH were reviewed according to the location of the lesion (cerebral cortex, brainstem, spinal cord, and peripheral nerve). The following pathogenic mechanisms have been suggested: vasospasm, cerebral ischemia, hydrocephalus, compression of cerebral cortex, neural injury, spinal cord infarction, and radiculo-neuropathy. Considering the high incidence of aneurysmal SAH and motor weakness following aneurysmal SAH, we believe that the pathogenic mechanisms of motor weakness have been relatively understudied. More effort should be taken to investigate this important topic.

Subarachnoid Hemorrhage*

Introduction: Spontaneous acute subdural hematoma (ASDH) is rare and comprises 2.6% of all ASDH. In one recent study, only 178 spontaneous ASDH were documented. However, only 1 case was attributed to dural arteriovenous fistula (dAVF). Vascular malformations cause less than 10% of subarachnoid hemorrhage (SAH). Spontaneous ASDH and SAH occurring together are extremely rare. Literature is scarce on cases with dAVF of the occipital lobe as a cause of simultaneous spontaneous ASDH and SAH. Objective: This paper aims to present a case of a spontaneous acute subdural hematoma and subarachnoid hemorrhage caused by a dural arteriovenous fistula of the occipital lobe, along with its clinical presentation, diagnosis, and treatment. Case Summary: A 44-year-old Filipino male with no history of trauma presented with severe headache, vomiting, and decreasing sensorium – CT scan revealed acute parenchymal bleed in the left occipital lobe with subarachnoid extension and subdural hematoma in the left fronto-parieto-temporal convexity along the tentorium cerebelli and posterior interhemispheric falx. Due to the location of the lesion seen on the CT scan and the gender distribution, Arteriovenous malformation (AVM) was initially considered, thus proceeded to computed tomography angiogram (CTA) to establish the diagnosis of vascular anomaly, however, revealed dAVF instead. Four-vessel angiogram was done to assess the tributaries of the dAVF and confirmed the diagnosis. Complete obliteration of dAVF of the occipital lobe was done with Onyx Embolization in one session. Conclusion This is the first case of Borden type II, Cognard type IIa+IIb dAVF, as reported in this institution. Although extremely rare as a cause of SAH and ASDH, dAVF should be considered a differential diagnosis in patients with no identifiable common cause of the new onset of severe headache and poor neurologic status.
Subarachnoid Hemorrhage

We present a 66-year-old male presenting with sudden onset of headache. Medical decompression was done and neuroimaging of plain cranial CT angiogram (CTA) and CT venogram (CTV) showed components of subarachnoid hemorrhage, intracerebral hemorrhage and hyperdense appearance of the superior sagittal sinus and proximal left transverse sinus. The following were done to look for etiologic factors: 1. fungal swab to determine the cause of the intracerebral hemorrhage secondary to venous thrombosis as the patient presented with a chronic history of sinusitis, 2. coagulopathy workup to look for a hypercoagulable state, and 3. workup for systemic disease of autoimmune in etiology. Anticoagulation was safely initiated within several days given the regression of the intracerebral hemorrhage along with stable findings of subarachnoid hemorrhage. Here we report cerebral venous sinus thrombosis rarely presenting as acute subarachnoid hemorrhage and intracerebral hemorrhage.

Most of Tarlov or perineurial cysts remain asymptomatic throughout the patient's life. The pathogenesis is still unclear. Hemorrhage has been suggested as one of the possible causes and trauma with resultant hemorrhage into subarachnoid space has been suggested as an origin of these cysts. However, Tarlov cysts related to spontaneous subarachnoid hemorrhage has not been reported. The authors report a case of Tarlov cyst which was symptomatic following spontaneous subarachnoid hemorrhage.
