Conclusion
Bing-Neel syndrome remains a very rare complication of WM above all the
tumoral form [1, 2, 6, 8]. This uncommon entity might sometimes
reveal the monoclonal gammopathy like in our case [1, 6]. Thus,
Bing-Neel tumor should be included in the differential diagnosis of not
only intra-axial but also extra-axial tumors such as meningioma. The
Prognosis improve in time with some long-term survival more than 10
years after successful treatment [14].
