A 45-year-old female, known case of IgA kappa multiple myeloma on lenalidomide, bortezomib, and dexamethasone regimen for the past 12 months, presented to our clinic with a week long history of holocranial headache associated with diplopia and left-sided facial deviation. Examination revealed left-sided cranial nerve VI and right-sided cranial nerve VII (LMN type) palsies.

Contrast-enhanced magnetic resonance imaging of brain was normal. However, cerebrospinal fluid (CSF) cytology [Figure 1] showed many plasma cells with round-to-oval eccentric cart-wheel like nuclei and moderate amount of cytoplasm. CSF protein electrophoresis was also positive for a “monoclonal” band for IgA Kappa. Serum kappa: lambda ratio was elevated at 1.99, and a repeat bone marrow biopsy showed large aggregates of plasma cells implicating concurrent systemic relapse.
Figure 1: (a and b) Cerebrospinal fluid cytospin smears showing sheets of plasma cells with eccentrically placed nuclei and cart-wheel chromatin. In addition, scattered, binucleated, and multinucleated plasma cells and plasma blasts with central nuclei and prominent nucleoli are also seen (a: May Grunwald Giemsa, ×20; b: Papanicolaou, ×20)

A prompt lumbar puncture and CSF cytology examination can clinch the diagnosis of central nervous system (CNS) pathology in a large number of benign and malignant disorders. CNS infiltration by multiple myeloma though rare should be suspected in patients who present with neurological manifestations.[1] Leptomeningeal infiltration by multiple myeloma carries a very poor prognosis with reported median overall survival of 7 months or less following its diagnosis.[2]
