STUDY DESIGN Clinical case report of atlantoaxial rotatory fixation (AARF) in a girl presenting with torticollis and neck pain. OBJECTIVE To report this rare case that was successfully treated with long-term traction and a brace. SUMMARY OF BACKGROUND DATA AARF is a rare kind of subluxation that is a pathologic fixation of the atlas on the axis. It is(More)
A ventricular diverticulum is usually found in patients with long-standing severe obstructive hydrocephalus that may extend into the supracerebellar cistern. The route involved in the supracerebellar extension of the ventricular diverticulum is believed to originate through the tela choroidea of the temporal choroid plexus or of the antral choroid plexus.(More)
Massive intracranial hemorrhage is a very rare initial presentation of cerebellar pilocytic astrocytomas. There are no reports in the medical literature on a cerebellar pilocytic astrocytoma presenting with intratumor bleeding (ITB), subarachnoid hemorrhage (SAH), and subdural hematoma (SDH). A 15-month-old boy presented with lethargy and nausea to our(More)
We report a case of a 70-year-old man harboring a wide-necked thrombosed giant aneurysm of the left middle cerebral artery (MCA) on the M1 segment. The patient presented with generalized tonic-clonic seizures. A computerized tomography scan showed a calcified aneurysmal wall with perianeurysmal swelling. The aneurysm was successfully embolized using(More)
Surgery has a key role in the treatment of malignant peripheral nerve sheath tumors (MPNSTs), but the resectability of paraspinal MPNSTs is only 20%. Therefore, spinal MPNSTs show frequent recurrence and poor prognosis. Local recurrence is much more common than metastasis for MPNSTs, and surgery still has a key role in the treatment of local recurrence.(More)
In this study, we evaluated the wall of saccular cerebral aneurysms (SCAs) using two-dimensional double inversion recovery black-blood sequence (BBDI). We examined 14 patients with an unruptured SCA (USCA). The BBDI was peripheral-pulse gated, and was acquired during the mid-diastolic period. We evaluated whether the aneurysmal wall could be visualized with(More)
BACKGROUND Solitary involvement of the sphenoid sinus has rarely been reported in non-Hodgkin's lymphoma. Isolated oculomotor nerve palsy is uncommon as an initial presentation of malignant tumors of the sphenoid sinus. CASE PRESENTATION A 53-year-old woman presented with a three-month history of headache and diplopia. Neurological examination revealed(More)
We report a unique case of bilateral mirror image M1 aneurysms, one of which was an unruptured aneurysm arising from the proximal end of right middle cerebral artery fenestration with long loop and the other ruptured aneurysm from the contralateral side. We clipped ruptured aneurysm first and unruptured one in three months after the first operation. The(More)
A 59-year-old Asian woman suffered from a TCH followed by sudden, binocular blurred vision, mimicking pituitary apoplexy. The diagnostic workup (including fluorescein angiography, MRI of the brain, and CSF analysis) showed severe optic disc swelling and dye leakage of multiple faint hyperfluorescent spots at retinal pigment epithelium level, diffuse(More)
BACKGROUND It is not difficult to find localized skull ballooning or macrocrania in patients with intracranial arachnoid cysts. However, there have been no previous reports regarding large localized skull protuberant deformities resembling a war helmet. The authors report with a review of literature a case of an adult with helmetlike skull deformity(More)
