“…Many authors have regarded the papillary structures as a morphological marker for malignant behaviour 7,10 , 15 . On the other hand, many researchers have indicated that papillary formation is just a pattern without malignant potential when it is not accompanied by cytological malignancy 8,16 , 17 . Indeed, it has been observed that the presence of a high number of pleomorphic nuclei, mitotic figures and necrosis in many cases of papillary meningioma, are related to aggressive/malignant behaviour 16 .…”

“…Several cases of intracranial hypertension due to non-thrombotic dural sinus occlusion have been reported. [3][4][5][6][7][8][9]11) Most of these cases occurred in patients with malignant neoplasms such as metastatic sarcoma, metastatic carcinoma, malignant lymphoma, or primary hemangiopericytoma.…”

“…2) In contrast, nonthrombotic obstruction of the SSS by a midsagittal neoplasm rarely causes acute intracranial hypertension. [3][4][5][6][7][8][9]11) We present a case of a metastatic malignant lymphoma, which manifested as intracranial hypertension due to non-thrombotic SSS occlusion.…”

A 57-year-old female presented with intracranial hypertension secondary to non-thrombotic superior sagittal sinus occlusion manifesting as acute onset of headache, vomiting, and disorientation. She had a history of intrapelvic malignant lymphoma. Neuroimaging and tumor biopsy revealed that both the superior sagittal sinus and the straight sinus were occluded by metastatic deposits of malignant lymphoma. Her clinical symptoms were remarkably improved by irradiation and chemotherapy, and the affected sinuses were angiographically recanalized.

“…12,16 The cases with sufficient data (n ¼ 29) were separated into two groups: those who underwent GTR and those that underwent STR. 3,4,[6][7][8][9][10][11]14,15,18,[23][24][25][26][27][28][29] These initial groups were further subdivided into those that received GTR only in addition to STR only and those that received STR in addition to RT. Data were aggregated and analyzed using Microsoft Excel.…”

Systematic Analysis of Outcomes for Surgical Resection and Radiotherapy in Patients with Papillary Meningioma

Introduction?Papillary meningiomas (PMs) are characterized by their aggressive nature and high rate of recurrence. Due to their rarity, studies examining the relationship between treatment and clinical outcomes for this disease are limited. Gross total resection (GTR) with or without radiotherapy (RT) is considered the standard treatment; however, when GTR is not feasible, subtotal resection (STR) followed by RT may be an effective alternative. In this study, we analyzed the clinical outcomes in patients who either underwent GTR alone, GTR followed by RT, STR alone, or STR followed by RT. Methods?A systematic analysis was performed to identify PM patients with sufficient follow-up and outcome data, as measured by recurrence. Patient data lacking extent of resection, follow-up, or recurrence information were excluded. Results?A total of 29 patients with PM were treated with resections (23 GTRs and 6 STRs).The mean age and mean follow-up of patients in this study were 32.3 years and 42.1 months, respectively. Of these patients, 58.6% experienced recurrence. Overall, 47.8% of patients who underwent GTR experienced recurrence. These patients also demonstrated improved survival compared with STR. Among patients whose tumors were only partially excised, a recurrence rate of 83% was observed. Conclusion?Our results confirm that GTR results in fewer recurrences compared with STR, supporting GTR as the treatment of choice for PM. Furthermore, GTR in conjunction with RT resulted in improved survival compared with GTR alone. When GTR was not feasible, STR with RT was associated with improved survival compared with STR alone. Future studies with more outcome data are needed to elucidate the optimal treatment for this rare disease.
