Neoplastic meningitis in unknown primary neoplasms
Journal of Clinical Oncology, 200611517 Background: Neoplastic meningitis (NM) is diagnosed in 5–8% of patients with solid tumors. Unknown primary cancers (UPC) constitute 1% to 7% of NM cases. There is scattered data addressing NM in the context of UPC. Here we characterize the clinical manifestations, prognostic factors and survival outcomes in patients with NM from UPC.

Benign and Malignant Neoplasms, Meninges, Rat
1988Benign meningeal neoplasms such as meningiomas and granular cell tumors are characteristically well circumscribed, spherical, gray-white discolored masses or thickenings, intimately connected with the meninges. The meninges over the frontal, parietal, and temporal portion of the cerebrum and the dorsal and lateral portions of the cerebellum are the ...

Child's Nervous System, 2010
Spinal seeding of primary malignant intracranial tumors via CSF is common. However, this is rare in low-grade glial tumors. Cranial leptomeningeal metastasis of primary spinal cord low-grade gliomas at diagnosis or relapse is extremely rare. Leptomeningeal metastasis of spinal cord low-grade tumors may mimic tuberculous meningitis in children.

Meningeal melanocytosis: a possibly useful treatment for a rare primary brain neoplasm
Journal of Neurology, 2011Meningeal melanocytosis (MM) is a rare primary leptomeningeal neoplasm of melanotic cells with a slow growing diffuse pattern [1]. It may occur as neurocutaneous melanosis associated with congenital cutaneous nevi, or as isolated MM. MM has a poor prognosis both due to melanocyte malignization and because of progressive meningeal thickening [2–4].

Hypoglycorrhachia (Low Cerebrospinal-Fluid Sugar) in Diffuse Meningeal Neoplasm
New England Journal of Medicine, 1963IN the difficult and diagnostic problem case of poorly localized Central-nervous-system disease a low concentration or absence of sugar in the spinal fluid may indicate neoplastic infiltration of the leptomeninges. Little attention to this helpful clinical finding has been paid in the medical literature for some time.

Background Solitary fibrous tumour (SFT) is a rare mesenchymal tumour now described at many locations, including the meninges. Intracranial SFT closely resembles meningioma clinically and radiologically, and, like meningioma, reports of meningeal SFT suggest a relatively benign behaviour after complete resection ...

Postoperative bacterial meningitis (PBM), a severe complication after skull base tumor surgery, poses a challenge in early diagnosis, which is crucial yet often delayed due to the inconclusive nature of current diagnostic methods relying on clinical symptoms and CSF analysis.

Associated chronic subdural haematoma and meningeal neoplasm. Two case reports.
Journal of neurosurgical sciences, 1994The authors present two cases of non-traumatic subdural haematomas associated with a meningioma. Relevant literature is reviewed and the pathogenesis of this rare condition is discussed.
