Tumor lysis syndrome (TLS) is a potentially life-threating complication of tumors or chemotherapy treatment. TLS commonly occurs in hematological malignancies, but it is very rare in patients with a solid tumor. In cases of solid tumors, TLS usually occurs spontaneously and after the initiation of anticancer therapy, and it has a high mortality rate. We(More)
A 56-year-old man presented with a very rare true neurenteric cyst in the conus medullaris without evidence of vertebral or visceral anomaly manifesting as a 6-month history of mild low back and bilateral inguinal pain. No motor weakness was found in the bilateral lower extremities. He had also suffered dysesthesia in the bilateral feet for several weeks(More)

We encountered a case of NF-1 in which severe bleeding was observed from a neurofibroma under the scalp due to minor trauma. Only four similar cases have been reported in the past literature and we believed that(More)
The authors describe a unique presentation of Wegener granulomatosis (WG) manifesting predominantly as meningitis. Magnetic resonance imaging demonstrated diffuse meningeal enhancement, including the pia mater, in a 28-year-old man with meningitis. A diagnosis of atypical WG was based on the findings of a dural biopsy sample and an elevated cytoplasmic(More)
A rare case of falx meningioma with extensive vacuolization was reported. A 57-year-old woman was admitted to Okayama University Hospital because of numbness in her left lower limb. A plain CT scan showed a hypodense mass in the right frontal region with marked enhancement after contrast medium injection. MRI on T1 weighted images showed low intense mass(More)
Primary intracranial T cell type malignant lymphoma is extremely rare. Only 8 cases are reported in the literature so far. In this paper, a case with this type of malignant lymphoma is reported. A 41-year-old man was admitted because of abnormal behavior. Enhanced CT scan demonstrated high density mass and perifocal low-density area in the right frontal(More)
