OBJECTIVE In the transsylvian approach to the mediobasal temporal structures, the temporal horn is approached through the floor of the sylvian fissure. The anterior bundle of the optic radiations (Meyer's loop) courses between the floor of the sylvian fissure and roof of the temporal horn and could be damaged in this approach. This study was designed to(More)
OBJECTIVE We sought to investigate the three-dimensional structure of the white matter of the brain by means of the fiber-dissection technique and diffusion-tensor magnetic resonance imaging to assess the usefulness of the combination of both techniques, compare their results, and review the potential functional role of fiber tracts. METHODS Fifteen(More)
OBJECT The goal in this study was to examine the microsurgical and tractographic anatomy of the claustrum and its projection fibers, and to analyze the functional and surgical implications of the findings. METHODS Fifteen formalin-fixed human brain hemispheres were dissected using the Klingler fiber dissection technique, with the aid of an operating(More)
OBJECTIVE There has been inconsistency about definition of the temporal stem despite of several descriptions demonstrating its microanatomy using fiber dissection and/or diffusion tensor tractography. This study was designed to clarify three dimensional configurations of the temporal stem. METHODS The fronto-temporal regions of several formalin-fixed(More)
Kissing aneurysms, a particular type of multiple aneurysm are rare. A kissing aneurysms was identified at the distal anterior cerebral artery (ACA) in a 59-year-old male patient diagnosed with subarachnoid hemorrhage (SAH). The use of three-dimensional intracranial CT angiograms revealed that kissing aneurysms (that is, an aneurysm with a bilateral(More)
Acute subdural hematoma is usually a neurological emergency that requires hematoma evacuation or close observation. However, spontaneous resolutions of an acute subdural hematoma without surgical interventions have been reported rarely. We report on a case who showed rapid resolution of an acute subdural hematoma with neurological improvement and review the(More)
Intraventricular cavernous hemangiomas are uncommon. Among them, those occurred at the foramen of Monro in the third ventricle may be of particular interest because of its rarity, development of hydrocephalus, being differentiated from other brain lesions. We present a rare case of intraventricular cavernous hemangioma at foramen of Monro which was resected(More)
Primary intracranial malignant melanoma is a very rare and highly aggressive tumor with poor prognosis. A 66-year-old female patient presented a headache that had been slowly progressing for several months. A large benign pigmented skin lesion was found on her back. A brain MRI showed multiple linear signal changes with branching pattern and strong(More)
OBJECTIVE Spinal dysraphism defects span wide spectrum. Wound dehiscence is a common postoperative complication, and is a challenge in the current management of cerebrospinal fluid (CSF) leaks and wound healing. The purpose of this study is to evaluate the risks of CSF-related morbidity in the surgical treatment of spinal dysraphism. METHODS Ten patients(More)
