“…Combined types of meningiomas frequently coexist in low-grade meningiomas, but are not uncommon in high-grade meningiomas, like rhabdoid or papillary types. No previous case of primary intraspinal occurrence has been reported in the previously reported rhabdoid papillary meningiomas; all 15 cases of rhabdoid papillary meningiomas occurred in the brain except for the present case, and 12 of them showed recurrence, intraspinal and/or intracerebral [4,5,6,7,8,9,10,11,12]. Six cases, including the present one, showed leptomeningeal seeding.…”

“…In contrast to the relatively common phenomenon of combined types of meningioma of low grade, combined rhabdoid and papillary meningioma resembling ependymoma was first described by Perry et al [2] and Kepes et al [3]. To date, 14 cases of rhabdoid papillary meningiomas have been reported, and all of the previously reported cases occurred in the brain meninges [4,5,6,7,8,9,10,11,12]. To the best of our knowledge, no case of primary intraspinal rhabdoid papillary meningioma has been reported in the literature.…”

Background: Both rhabdoid and papillary meningioma are rare variants of meningioma categorized as WHO grade III. Here, we report a rare case of combined rhabdoid papillary meningioma with discussion of its differential intraoperative cytologic diagnoses. Case: The patient was a 72-year-old female who presented with a huge mass at the cervical spine on MRI. The crush smears showed a radially arranged pattern of elongated tumor cells centered around the vessels, which formed a pseudorosette-like papillary structure, as well as singly scattered large gemistocyte-like rhabdoid cells with distinct cell borders. Rhabdoid cells had eccentrically placed vesicular nuclei with plump, fibrillary-to-hyaline cytoplasm with short broad processes. Nuclei had occasional nuclear inclusions with no nuclear grooves. Conclusion: Rhabdoid papillary meningiomas, encountered less often, should be distinguished from metastatic tumors of rhabdoid or papillary configuration, astrocytomas, ependymomas and atypical teratoid/rhabdoid tumor. Search for eosinophilic hyaline cytoplasm, rather than a fibrillary one, is critical for distinguishing it from other commonly encountered spinal cord tumors in the total absence of meningothelial whorls, like the present case. We also emphasize that the present case is the first case of rhabdoid papillary meningioma with primary manifestation in the spinal cord.

“…This is similar to other previously reported cases of RM in the literature where the mean age at presentation was 46.1 years (range, 9 -84), also with a female predominance (female-to-male ratio, 24:16). [8][9][10][12][13][14][15] Atypical and malignant meningioma usually present earlier than benign meningioma. 4 However, in our study, the age population of the RM was not significantly different from benign meningiomas.…”

“…Radiotherapy was given to 4 patients. After a mean follow-up of 86.6 months (except in 2 cases there was no follow-up), there was a recurrence in one child 4 months after the operation [31] , and one patient died at 25 years after the fi rst operation [32] . The other children who were followed were alive with stable disease, or with no evidence of recurrence.…”
