Extensive Pachymeningeal Dissemination of Glioblastoma Mimicking Chronic Subdural Hematoma: A Case Report.

Meningeal dissemination (MDS) of glioblastoma is rare, although its incidence might have been underestimated. MDS of glioblastoma has a fatal course. Thus, rapid and precise diagnosis of MDS is important for further palliative treatment. Unfortunately, MDS of glioblastoma could be diagnosed at a delayed time, causing failure to treat patient optimally. Herein, we present a case of a 56-year-old male with MDS of glioblastoma mimicking chronic subdural hemorrhage (CSDH) after head trauma due to slip down. During treatment for CSDH, MDS of glioblastoma was not controlled appropriately. The patient succumbed to MDS of glioblastoma at 9 weeks after the date of diagnosis of CSDH which could be an MDS.
