The 5-aminolevulinic acid (5-ALA)-induced tumor fluorescence is a useful intraoperative marker for the diagnosis and the detection of various malignancies, but its use in meningioma is only reported infrequently. In meningioma, a complete resection of the tumor mass is crucial for the prevention of recurrence and postoperative morbidities. Deep sylvian meningioma is a rare type of meningioma wh...

The authors present a case of familial clear cell meningioma in which the proband is a child with an intraspinal tumor. The clear cell meningioma variant has recently been studied. The literature regarding clear cell meningioma is reviewed.

OBJECTIVE A rare subtype of meningioma, sclerosing meningioma is not included in the current World Health Organization classification of meningiomas and is classified into the category of other morphological variation subtypes. Sclerosing meningioma is often misdiagnosed to other non-benign meningioma or malignant neoplasm, so it is important to diagnose sclerosing type correctly. We analyzed t...

Since the atomic bomb explosions in Hiroshima and Nagasaki, high incidences of leukemia, thyroid cancer and other tumors have been reported as atomic bomb-induced tumors. We investigated the incidence of meningioma among Hiroshima atomic bomb survivors. Sixty-eight patients surgically treated for meningioma who had been within 2.0 km of the hypocenter of the explosion were identified. Six hundr...

Ionizing radiation is the most established risk factor for meningioma formation. Our aim was to evaluate the main effect of selected candidate genes on the development of meningioma and their possible interaction with ionizing radiation in the causation of this tumor. The total study population included 440 cases and controls: 150 meningioma patients who were irradiated for tinea capitis in chi...

Two patients are presented with a head-bobblng "tic" classically associated with a suprasellar cyst. The first of these showed hypothalamic, neuroendocrinological and limbic abnormalities not previously described, although with a classic arachnoidal suprasellar cyst. The second of these patients showed head-bobbling behaviour during the first years of life as a manifestation of one out of many ...

Craniopharyngiomas comprise approximately 3% of all intracranial tumors. Preservation of pituitary function after resection represents a significant challenge due to their location in the anterior skull base and aggressive local behavior. We report a case of a 79-year-old woman with a large suprasellar craniopharyngioma who presented with visual loss. MRI revealed a suprasellar cystic mass with...

Cells resembling bone marrow mesenchymal stem cells (BM-MSCs) have been isolated from glioma specimens; however, little is known about the existence of mesenchymal stem-like cells (MSLCs) in meningioma. Here, we hypothesized that cells similar to BM-MSCs exist in meningioma specimens and sought to investigate whether these putative meningioma stroma MSLCs (MS-MSLCs) could be isolated. To this e...

Meningioma merupakan jenis neoplasma intrakranial ekstraaksial yang paling umum dijumpai. Seiring dengan berkembangnya ilmu genomik, beberapa studi mulai meneliti asosiasi kejadian meningioma keberadaan single-nucleotide polymorphisms (SNPs). Penelitian ini bertujuan untuk melihat hubungan antara SNP risiko terjadinya meningioma. Penelusuran literatur dilakukan pada berbagai database kemudian d...

Schwannoma is a benign peripheral nerve sheath tumor originating from Schwann cells. Most intracranial schwannomas arise from vestibular nerve and schwannoma in the suprasellar region is extremely rare. A 64-year-old man presented with walking disturbance and blurred vision for three months. Lateral hemianopsia in the left eye and brachybasia were observed. Magnetic resonance imaging revealed a...
