We report a rare case of a patient with Moyamoya syndrome who presented with intracerebral hemorrhage resulting from rupture of a middle meningeal artery pseudoaneurysm. This 38-year-old woman was unconscious and hemiplegic when she was admitted to our hospital. The patient had mental retardation as a result of tuberculous meningitis infection at the age of one year. On radiologic examination, she had intracerebral hemorrhage in the right temporo-parietal lobe and an aneurysm in the middle meningeal artery with right internal carotid artery occlusion. The patient underwent surgical treatment for the hemorrhage and aneurysm. The radiologic data, intraoperative findings, and pathology were consistent with a diagnosis of pseudoaneurysm. In the current report, we describe a rare case of a patient with a history of tuberculous meningitis who developed Moyamoya syndrome and pseudoaneurysm, which resulted in a ruptured middle meningeal artery pseudoaneurysm and brain hemorrhage.

Intracranial hemorrhage is common and is caused by diverse pathology, including trauma, hypertension, cerebral amyloid angiopathy, hemorrhagic conversion of ischemic infarction, cerebral aneurysms, cerebral arteriovenous malformations, dural arteriovenous fistula, vasculitis, and venous sinus thrombosis, among other causes. Neuroimaging is essential for the treating physician to identify the cause of hemorrhage and to understand the location and severity of hemorrhage, the risk of impending cerebral injury, and to guide often emergent patient treatment. We review CT and MRI evaluation of intracranial hemorrhage with the goal of providing a broad overview of the diverse causes and varied appearances of intracranial hemorrhage.

Benign primary headaches are common during the postpartum period. However, there are several other kinds of headaches caused by specific underlying pathologies like post-dural puncture headache (PDPH), pregnancy induced hypertension, cortical vein thrombosis, posterior reversible encephalopathy syndrome (PRES), subarachnoid hemorrhage, intracranial hemorrhage, brain tumor, and so on. These headaches are rare but each can be life threatening conditions when diagnosis is delayed. If a patient was treated for another type of headache, like a PDPH, the diagnosis would be even more difficult. We report on the case of a 24 year-old woman who suffered with PDPH followed by postpartum eclampsia with PRES.

Stroke classified into ischemic and hemorrhagic subtypes, is among the most devastating diseases for human being. Certain drugs could increase the blood viscosity, thereby increasing the potential risk of ischemia. Anti-platelet and anti-coagulation drugs, as the treatment of first choice, increase the risk of intracranial hemorrhage and death. Here, we are the first to propose the concept of drug-related stroke, and discuss the treatment strategy for patients who are complicated with intracranial hemorrhage or plan to receive neurosurgical operation during either anti-platelet or anti-coagulation medication. We hope to arouse the attention for drug related stroke among the clinicians and offer recommendation for clinical intervention.

This study was aimed to summarize the clinical and pathological features of patients with acute leukemia combined with intracranial hemorrhage. The clinical and pathological data of 41 adult patients diagnosed as acute leukemia in our hospital from 1953 to 1990 year were analyzed retrospectively. The results showed that there were 35 cases of AML, 6 cases of ALL; 9 cases in clinical hematologic remission, 32 cases in non-remission, 3 cases of AL with hypertension, 2 cases of AL with diabetes, 4 cases of AL with sepsis, 19 cases with WBC ≥ 100×10(9)/L; the pathologic examination showed 4 cases of AL accompanied with disseminated intravascular coagulation, 10 cases with prothrombin time INR ≥ 1.5, 26 cases with multifocal intracranial hemorrhage, 7 cases with single intracranial hemorrhage, 8 cases with diffused spotting intracranial hemorrhage; the examination also showed that 84 hemorrhage foci were found in 41 cases of AL, among them 46 foci located under cerebral cortex, 23 foci in cerebellum, 6 in basal ganglia, 5 foci in pons, 2 foci in thalamus, 2 foci in spinal cord. It is concluded that the intracranial hemorrhage is a major cause resulting in death of AL patients which should be think highly, and the diagnosis and treatment should be conducted through comprehensive analysis.

BACKGROUNDCerebral amyloid angiopathy (CAA) is one of the main causes of spontaneous intracranial hemorrhage (ICH). No established link is available between pathological scores of CAA and its outcome. This study aimed to identify the correlations between pathological severity and poor postoperative outcome in the Chinese population.

METHODSBetween May 2006 and April 2011, 367 consecutive patients who underwent surgery for CAA-related ICH in 71 hospitals throughout the mainland of China were enrolled in this study. Twelve months after surgery, we evaluated these patients' outcomes according to the modified Rankin Scale (mRS) and statistically correlated risk factors (demographics, medical history, pathological results, and surgical details) that are associated with a favorable (mRS < 3) and poor (mRS ≥ 3) outcome groups.

RESULTSRisk factors for poor postoperative outcome in 367 patients with CAA-related ICH included advanced age (OR 1.034, 95%CI 1.001 - 1.067, P = 0.042), CAA pathology severity (OR 2.074, 95%CI 7.140 - 16.25, P < 0.001), lobar hematoma (OR 0.225, 95%CI 0.104 - 0.486, P < 0.001), presence of intraventricular hemorrhage (OR 0.478, 95%CI 0.229 - 1.001, P = 0.050), and/or subarachnoid hemorrhage (OR 2.629, 95%CI, 1.051 - 6.577, P = 0.039).

CONCLUSIONSPoor postoperative outcome of patients with CAA-related ICH was more related to the severe pathological manifestation instead of other factors. Prior ischemia may present an early stage of CAA.

Sudden ascent to high altitudes beyond 2,438 m can cause life-threatening complications such as acute mountain sickness and high altitude cerebral and pulmonary oedema. We present a case of pituitary apoplexy in a young man who ascended to high altitude gradually, after proper acclimatisation. He developed headache, nausea, vomiting and persistent hypotension. Magnetic resonance imaging revealed an enlarged pituitary gland with haemorrhage. His hormonal estimation showed acute adrenal insufficiency due to corticotropin deficiency. The patient responded well to conservative medical management with hormonal replacement therapy. This is most likely the first reported case of high altitude-induced pituitary apoplexy in the literature.

OBJECTIVE: The more accurate calculate method was investigated according to the improved formula of intracranial hematoma using segment deducing. METHODS: The improved formula was deduced to calculate the intracranial hematoma using the volume formula of the solid geometry. The volume of intracranial hematoma was measured as a related accurate standards using software. The volumes of intracranial hematoma calculated by the improved formula, Tada's formula and the software were compared. RESULTS: The measure accuracy of the improved formula was higher than that of Tada's formula, and showed a similarity with that by using software method. CONCLUSION The improved formula method shows a more accurate result than Tada's formula, and can be used in forensic practice.

OBJECTIVE: To investigate the relationship between behavioral changes and cell proliferation in subventricular zone (SVZ) after intracerebral hemorrhage (ICH) in adult rats. METHODS: Forty male Sprague-Dawley rats were randomly assigned into a behavioral test group (n = 19) and a bromodeoxyuridine (Brdu) immunohistochemical staining group (n = 21). ICH was induced by stereotactial injection of collagenase type VII into straitum. Proliferating cells were labeled by injection intrapenitoneally of bromodeoxyuridine in a pulse protocal. Rats were killed on day 2, 7, 14, and 28 after the ICH. Behavioral test and bromodeoxyuridine immunohistochemical staining were performed.Behavioral change was tested by forelimb placing test, Berderson's grade and corner turn test in rats. Cell counting of bromodeoxyuridine immunoreactive cells in SVZ was performed. RESULTS: There were marked neurological deficits by day 2 after the ICH, with progressive recovery of function over 4 weeks. A significant increase in the number of bromodeoxyuridine immunoreactive cells in the ipsilateral and cortralateral SVZ was observed from 2 to 14 days with a peak at day 7 after the ICH compared with the sham group.The bromodeoxyuridine immunoreactive cells decreased to control level 28 days after the ICH. CONCLUSION Proliferation of cells in SVZ corresponds well with behavioral recovery after the ICH, which indicates SVZ cells may be involved in the repairing process after the ICH.
