An 18-year-old girl presented with central pontine myelinolysis (CPM) following surgery for craniopharyngioma. Postoperatively, the patient developed diabetes insipidus with remarkable fluctuation of serum sodium level, suffered a seizure, and developed mental state changes and quadriparesis. Magnetic resonance (MR) imaging obtained soon after the(More)
A 66-year-old woman with primary Sjogren syndrome developed syringomyelia following two episodes of subarachnoid hemorrhage (SAH) due to the rupture of basilar artery aneurysms. Gait disturbance and abnormal sensation with pain over the foot and abdomen appeared 3 years after the last SAH. Magnetic resonance (MR) imaging revealed a syringomyelia throughout(More)
BACKGROUND Although Duret haemorrhage of the brainstem caused by descending transtentorial herniation is considered fatal, a few cases have been reported to have good outcome. Moreover, most patients with Duret haemorrhage have severe primary brain injury and the potential outcome of those with mild primary brain injury remains unknown. CASE REPORT This(More)
UNLABELLED The Rubinstein-Taybi syndrome (RTS) is defined congenital anomalies and is characterized by postnatal growth deficiency, microcephaly, specific facial characteristics, broad thumbs and big toes, and mental retardation. RTS displays an autosomal dominant inheritance pattern and is typically caused by cAMP response element-binding (CREB)-binding(More)
Volume management is critical for assessment of cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH). This multicenter prospective cohort study compared the impact of surgical clipping versus endovascular coiling on postoperative hemodynamics and pulmonary edema in patients with SAH. Hemodynamic parameters were measured for 14 days using a(More)
Granulocytic sarcoma consists of neoplastic granulocytic precursors and myeloblasts. It is a focal lesion seen in 2-10.9% of acute myelogenous leukaemia (AML) patients. It usually develops either concurrently with the AML or after a remission. On rare occasions, it may be an initial manifestation of AML. Most common involvement sites are bone, periostium,(More)
Ballism is characterized by continuous, coarse, flinging involuntary movements involving the limbs. Although persistent involuntary movements caused by cerebrovascular diseases mostly in middle-aged patients are well known, transient involuntary movements are an unusual manifestation of cerebrovascular diseases. We describe a rare case of reversible(More)
OBJECT It is reported that antimicrobial prophylaxis (AMP) reduces the incidence of surgical site infection (SSI) in neurological surgery. However, a great deal of variation exists regarding the type of antibiotics, dose, timing and duration. In this study, the authors analyzed the incidence of SSI comparing two different AMP protocols.
