BACKGROUND Expansive laminoplasty of several types has been proposed for patients with cervical multisegmental stenotic myelopathy to reduce postlaminectomy complications. Its effectiveness has not been fully explored by evaluating long-term results and magnetic resonance imaging (MRI) findings before and after surgery. METHODS We conducted a 5-year(More)
Recurrence of hypertensive intracerebral hemorrhage confirmed by computed tomography scan has rarely been reported. The authors have experienced nine cases of recurrent hemorrhage among 494 cases of hypertensive intracerebral hemorrhage. Recurrence rate was 1.8%. There were eight males and one female with an average age of 60.5 years. Six cases had their(More)
We presented a case of secondary giant meningioma with dense calcification (brain stone) after radiation therapy for primary ependymoma removed 25 years before. A 31-year-old man was referred to our hospital because of generalized convulsion. He had received extirpation of an ependymoma in the left frontoparietal region and postoperative radiation therapy(More)
A 15-year-old boy was referred to our hospital with a rare case of inflammatory pseudotumor (IP) in the lateral ventricle manifesting as complaints of headache and low-grade fever. Computed tomography and magnetic resonance imaging demonstrated a well-demarcated and enhanced tumorous lesion in the right lateral ventricle. Intraoperative findings showed a(More)
The case of a large solid hemangioblastoma embedded wholly in the medulla oblongata is reported. Preoperative magnetic resonance imaging provided precise indications of the anatomical location and radiologic features of the tumor, which facilitated its total removal by microsurgery. Short-latency somatosensory evoked potentials were monitored throughout the(More)
Spinal cord injury is a rare but considerable complication of acupuncture. A case with cervical spinal cord injury caused by a broken acupuncture needle was reported and sixteen previously reported cases including our case were reviewed. A 49-year-old woman was treated by herself with acupuncture on the nuchal region for occipitalgia, and the needle was(More)
A 57-year-old male was admitted with pulsatile tinnitus and hearing disturbance of the right ear and right peripheral facial palsy. Otological examination revealed a pulsatile red mass in his right ear and right conductive hearing disturbance. CT and MRI showed the mass lesion at his right middle fossa near the geniculate ganglion. Right external carotid(More)
OBJECTIVE We report a 44-year old man with ectopic adrenocorticotropic hormone (ACTH) syndrome caused by bronchial carcinoid that developed Cushing syndrome. METHODS We performed several imaging studies, including chest and abdominal CT, for exploration of nodules and selective pulmonary arterial sampling for localizing a source of ectopic ACTH(More)
