Endoscopic Endonasal Management of an Ethmoidal Osteoma With Orbital Extension
Osteomas are the most common benign tumors of nose and paranasal sinuses. Endonasal endoscopic surgery began to find its place in frontoethmoidal osteoma surgery instead of open procedures. In this paper, an ethmoidal osteoma case with orbital extension totally resected with endonasal endoscopic approach was reported. The patient rapidly recovered postoperatively without any morbidity and with great cosmetic result. There was no tumor recurrence during 7 months of follow-up. When compared with the previously used management modalities, endonasal endoscopic surgery for skull base lesions, including frontoethmoid osteomas, i...

Tibetan Patients With Intracranial Aneurysm
Conclusions: A relatively high proportion of the patients had rare aneurysms, including pseudoaneurysm. Thus, risks in the treatment were remarkably high. Sufficient prediction and preparation are important to cope with unexpected intraoperative situations. The patients did not have a higher cerebral infarction rate under hypervolemic hypertensive hemodilution (3H) therapy. (Source: Neurosurgery Quarterly)

A Case Report of Sturge-Weber Syndrome With Gelastic Seizures
We report a case of 7-year-old boy who presented with a deep purple nevus of 5×7 cm on left side of the face since birth and gelastic seizures. Clinically, gelastic episodes were diagnosed secondary to SWS that improved with aggressive seizure management and low-dose aspirin use. We have attempted to identify the pathophysiology of the rare episodes in SWS. The case report underlines that the epileptic phenomena of the SWS may manifest with gelastic seizures and need correct identification and appropriate response for optimal management by doctors.

Neuroprotective Effects of Rosuvastatin in Spinal Cord Ischemia-Reperfusion Injury in Rabbits
Background: This experimental study was performed to investigate the neuroprotective effects of rosuvastatin in a rabbit model of spinal cord ischemia-reperfusion injury.
Materials and Methods: Rabbits were randomized into 3 groups of 6 animals each: group 1 (control), group 2 (ischemia), and group 3 (rosuvastatin 5 mg/kg/d). Spinal cord ischemia was produced in rabbits by a 30-minute occlusion of the aorta by clamping with aneurysm clips; just caudal to renal artery divison and above the aortic bifurcation. Rosuvastatin was administered intraperitoneally before onset of occlusion, for 3 days. At 48 hours after ischemia, n...

New Measuring Method for the Volume of Intracerebral Hematoma
For the measurement of intracerebral hematoma volume, the medical staff prefers to use Dotian formula to estimate the volume for convenience. Dotian technique is a method that considers hematoma as a solid to measure, although the majority of hematomas are not in the form of regular solids, and different hematoma forms are seen when computed tomography (CT) scans are taken at different baseline, thickness, or layers. Hence, the Dotian formula cannot fully meet the clinical requirements .The author has written a VB program based on a polygon formula method, which depicts points through the CT images. Each CT is approximated...

A Case Report of Skull Hemangioma
We present this case because it is primary and rare, but more importantly, at surgery, it was found that these lesions infiltrated the local dura mater and subcutaneous tissue that was inconsistent with the benign concept. (Source: Neurosurgery Quarterly)

Correlation Between Angiographic Features and Subtypes of Fusiform Aneurysm of Vertebral and Basilar Artery: Based On a Single-Institution Experience
Conclusions: The subtypes of FAs were location specific, whereas ruptured FAs were mainly type II at VA without correlation with aneurysmal size. (Source: Neurosurgery Quarterly)

Double-loculated Calcification Chronic Subdural Hematoma: Case Report and Literature Review
Calcified chronic subdural hematoma (CCSDH) is a rare pathologic entity and, until recently, has been only published as case reports. We first present a patient with a double-loculated CCSDH who obtained good reexpansion after craniotomy to remove the thick calcified inner membrane and hematoma. In addition, we reviewed 46 cases in literature and conducted a summary about the incidence, clinical characteristics, radiologic findings, and therapeutic strategies of CCSDH. Surgical treatment for CCDSH with a sudden neurological deterioration is feasible and often results in neurological improvement; however, a crucial consider...

Massive Skull Occult Metastasis of Follicular Carcinoma: Report of a Rare Case
Follicular thyroid carcinoma accounts for 15% of thyroid cancer, which occurs more commonly in the elderly women. This type of thyroid cancer is usually characterized by a palpable nodule in thyroid gland, but occult metastasis of follicular thyroid carcinoma is rare and unusual. Herein, we report an 81-year-old woman with a history of palpable small mass at frontal bone with a progressive enlargement and an accelerated growth, with 1 in the last 12 months. At present, true size of tumor is 5.56×9.84 cm in frontal bone. Neuroimaging (computed tomography) of the skull bone demonstrated a lytic metastatic tumor. On the basi...

Cerebral Venous Sinus Thrombosis on Unenhanced CT
Conclusions: On CT, the CVST presented as the attenuation of the sinuses from high to isodensity with its resolution course. In the first week, the involved sinuses mainly appear as high density, then in 7 to 10 days decrease to mixed density as central high density and peripheral isodensity, and gradually to uniform isodensity at last. The secondary infarction and hemorrhage are important indirect signs of CVST. Understanding the abnormal density change of venous sinuses and intracerebral indirect signs on CT could improve our diagnostic sensitivity for CVST. (Source: Neurosurgery Quarterly)

A Case of Spontaneous Dissection of the Extracranial Internal Carotid Artery
This report presents a rare case in which carotid stenting was performed to treat spontaneous dissection of the internal carotid artery (ICA). A 35-year-old man presented with right hemiparesis and aphasia. Magnetic resonance imaging depicted fresh multiple infarctions in the left cerebral hemisphere with left ICA occlusion. The patient was placed on bed rest and medical therapy. However, magnetic resonance imaging and computed tomography angiography 6 weeks after the admission revealed that the extracranial carotid artery aneurysm progressively increased in size. Stenting was performed under local anesthesia and distal pr...

Surgical Revascularization During the Acute Phase of Stroke Caused by Near Occlusion of the Cervical Internal Carotid Artery
An 83-year-old woman was admitted with a diagnosis of transient symptoms with a left hemisphere infarction due to atherosclerosis. Despite the best medical treatments, her neurological symptoms gradually deteriorated. The color Doppler ultrasound (CDUS) and digital subtraction angiography (DSA) demonstrated a near occlusion of the left cervical internal carotid artery. Because the intracranial internal carotid artery (ICA) seemed patent on DSA, although CDUS also suggested that the intracranial ICA was also occluded, carotid endarterectomy was performed. However, magnetic resonance angiography performed immediately after t...
