Intraspinal intradural nodular fasciitis mimicking glioblastoma metastasis: a case report

: We report the case of a 78-year-old male patient suffering from right temporal glioblastoma with radiographic meningeal tumor spread. During the further course of the disease he developed a rapidly progressive paraplegia. An magnetic resonance imaging scan showed a contrast enhancing an intraspinal intradural lesion with compression of the myelon on segment Th 8/9. With a high suspicion of a spinal metastasis of the known glioblastoma, emergency spinal decompression and resection of the intradural mass was performed. However, histopathological evaluation revealed nodular fasciitis without any signs of glial origin.
