A rare case of spontaneous subarachnoid hemorrhage from newly developed cerebral aneurysm in glioblastoma patient is presented. A 57-year-old man was presented with headache and memory impairment. On the magnetic resonance image and the magnetic resonance angiography, a large enhancing mass was found at right frontal subcortex and intracranial aneurysm was not found. The mass was removed subtotally and revealed as glioblastoma. He took concurrent PCV chemotherapy and radiation therapy, but the mass recurred one month later after radiotherapy. He was then treated with temozolomide for 7 cycles. Three months after the completion of temozolomide therapy, he suffered from a subarachnoid hemorrhage due to a rupture of a small de novo aneurysm at distal anterior cerebral artery. He underwent an aneurysm clipping and discharged without neurologic complication.

Objective : The purpose of this study was to evaluate the risk factors of hematoma enlargement in patients with spontaneous intracerebral hemorrhage(ICH). Methods : A series of 214 ICH patients diagnosed by brain CT scan in our neurosurgery department from June 1995 to July 1998 were reviewed with clinical status, past medical histories, laboratory findings, CT findings and prognosis. Results : In 27 patients(12.6%), the second CT scan showed an enlarged hematoma. Age, sex, and site of hematoma were not related to hematoma enlargement. A long interval(>6 hours) between the onset and the 1st CT scan strongly reduced the incidence of hematoma enlargement. The incidence of hematoma enlargement significantly increased in patients with previous history of hypertension, cerebral infarction and ICH. This analysis also demonstrated the following independent factors predisposed to hematoma enlargement : initial high systolic blood pressure, high serum total protein, low serum albumin, low serum sodium, prolonged prothrombin time(>14 sec) and activated partial thromboplastin time(>29.5 sec), irregular hematoma shape, and combined intraventricular hemorrhage. Prognosis in the group of hematoma enlargement showed high mortality(48.1%) and poor outcome. Conclusion : Patients with previous history of hypertension, cerebral infarction and ICH, and with high systolic blood pressure, prolonged coagulation time, irregular hematoma shape and intraventricular hemorrhage in CT scan should be observed carefully. And, early surgical therapy of large hematoma and meticulous control of blood pressure may decrease the mortality and morbidity in patients with spontaneous ICH.

Objective : The purpose of this study is to identify any differential point in computerized tomographic[CT] findings between aneurysmal subarachnoid hemorrhage[ASAH] and traumatic subarachnoid hemorrhage[TSAH], which sometimes make us not confident in differentiation. Methods : CT of 142 ASAH and 82 TSAH patients over the last 2 years were retrospectively reviewed. We evaluated the thickness of SAH, the laterality of sylvian cisternal hemorrhage, the location, the number of involved cisterns, and the associated other lesions between two types of SAH. Results : Suprasellar cisterns and sylvian cisterns were most prominently and frequently involved cisterns in ASAH but cortical sulci and sylvian cisterns were most frequently involved in TSAH. Intraventricular and intracerebral hemorrhage were frequently seen in ASAH. Thickness of SAH over 1mm, bilateral sylvian SAH, multiple cisternal SAH were in favor of ASAH. The number of involved cisterns were more frequently seen in ASAH than in TSAH. In ASAH, bilateral sylvian hemorrhages were more frequently seen than in TSAH. Skull fracture, subdural hematoma, subgaleal hematoma, and hemorrhagic contusion were frequently associated with TSAH. Conclusion : As a result of our study, the authors conclude that when IVH, hydrocephalus, thick SAH > 1mm bilateral sylvian SAH, and multiple cisternal SAH are seen in CT, immediate angiography should be performed to rule out cerebral aneurysms whether associated with other traumatic lesions or not.

Objectives : This study was intended to understand characteristics of symptoms, oriental medicine prescription and laboratory test results according to elapsed time of stroke. Methods : Through the medical records of 205 stroke inpatients in the oriental medical hospital in the year 2010, we investigated manifested symptoms, administered oriental medicine prescription and clinical pathological examination results. Collected items were classified to depend on stroke types, cerebral infarction and hemorrhage. We analyzed association between manifested symptoms, the oriental medicine prescription, and laboratory test results of stroke patients and elapsed time. Chi-square tests were performed to determine the significance level of association. Results : All symptoms, prescriptions and laboratory test results in cerebral infarction patients were associated with elapsed time. Especially, symptoms, prescriptions and pathological examination results showed very high statistical significance with elapsed time (a symptom; chi-square(df)=164.3(22), p<0.001, prescription; chi-square(df)=93.5(22), p<0.001, and pathological examination results; chi-square(df)=164.3(22), p<0.0004). But in the case of cerebral hemorrhage, there was not statistical significance. Conclusions : The elapsed time of stroke may be an essential requisite in catching symptoms and prescribing for stroke patients in oriental medical treatment.

Oculomotor nerve palsy (ONP) with subarachnoid hemorrhage (SAH) occurs usually when oculomotor nerve is compressed by growing or budding of posterior communicating artery (PcoA) aneurysm. Midbrain injury, increased intracranial pressure (lCP), or uncal herniation may also cause it. We report herein a rare case of ONP associated with SAH which was caused by middle cerebral artery (MCA) bifurcation aneurysm rupture. A 58-year-old woman with clear consciousness suffered from headache and sudden onset of unilateral ONP. Computed tomography showed SAH caused by the rupture of MCA aneurysm. The unilateral ONP was not associated with midbrain injury, increased ICP, or uncal herniation. The patient was treated with coil embolization, and the signs of oculomotor nerve palsy completely resolved after a few days. We suggest that bloody jet flow from the rupture of distant aneurysm other than PcoA aneurysm may also be considered as a cause of sudden unilateral ONP in patients with SAH.

An 8-year-old female Eurasian otter (Lutra lutra) reared in a wetland center, died 2 h after sudden onset of astasia and dyspnea despite medical treatment. Gross examination of internal organs revealed 10 adult filarioid nematodes in the right ventricle of the heart and three between the left and right cerebral hemispheres. All nematodes were identified as Dirofilaria immitis by direct microscopy and polymerase chain reaction assay. Histopathological observation revealed multifocal hemorrhage in the cerebral subarachnoid space and focal necrosis with hemorrhage in the cerebellar parenchyma. Although rare, veterinarians should consider cerebral dirofilariasis as a differential diagnosis in unexplained neurological cases.

Unruptured non-traumatic dissecting aneurysm in the M4 segment of the middle cerebral artery (MCA) accompanied by complete occlusion of the ipsilateral internal cerebral artery (ICA) has never been reported. A 41-year-old man presented with an infarction manifesting as left-sided weakness and dysarthria. Magnetic resonance angiography revealed a subacute stage infarction in the right MCA territory and complete occlusion of the right ICA. Angiography demonstrated aneurysmal dilatation of the M4 segment of the right MCA. Surgery was performed to prevent hemorrhage from the aneurysm. The aneurysm was proximally clipped guided by Navigation-CT angiography and flow to the distal MCA was restored by superficial temporal artery-middle cerebral artery (STA-MCA) anastornosis. We report this rare case with literature review.

Burr hole drainage has been widely used to treat chronic subdural hematomas (SDH), and most of them are easily treated by simple trephination and drainage. However, various complications, such as, hematoma recurrence, infection, seizure, cerebral edema, tension pneumocephalus and failure of the brain to expand due to cerebro-cranial disproportion may develop after chronic SDH drainage. Among them, intracerebral hemorrhage after evacuation of a recurrent chronic SDH is very rare. Here, we report a fatal case of delayed intracerebral hemorrhage caused by coagulopathy following evacuation of a chronic SDH. Possible pathogenic mechanisms of this unfavorable complication are discussed and a review of pertinent literature is included.

Traumatic intracranial aneurysm rarely occurs after a head injury. The authors report a case of a 51-year-old man in whom subarachnoid hemorrhage was developed as a result of delayed traumatic aneurysmal rupture of the distal portion of the middle cerebral artery following a minor, closed-head injury. The unruptured aneurysm had been evident on the magnetic resonance image taken two days prior to onset of the subarachnoid hemorrhage. The clinical presentation and possible underlying mechanism are discussed with a review of pertinent literature.

We report a case of fatal duret hemorrhage (DH) in a patient with acute tentorial subdural hematoma and bilateral chronic subdural hematoma along the cerebral hemispheres. Preoperative CT angiography (CTA) revealed prominent parenchymal enhancement in the ventral pontomesencephalic area. After burr-hole drainage, a large hemorrhage developed in this area. The parenchymal enhancement in the CTA may reflect the pontomensencephalic perforating vessel injury, and may be a sign of impending DH of acute transtentorial downward herniation. Previous use of aspirin and warfarin might have potentiated the process of DH and increase the extent of the bleed.
