Anterior petrosal approach for petroclival solitary plasmacytoma.

ABSTRACT:

Background

Primary solitary plasmacytoma (PSP) of the skull base is a rare localized monoclonal plasma cell dyscrasia with normal or low plasma cell infiltration. Differentiating from other skull base tumors based on radiologic findings is difficult due to nonspecific features. PSP has a better prognosis after surgical resection and adjuvant radiotherapy, unless the tumor progresses to multiple myeloma (MM). Nonetheless, 50-60% progress to MM within a median time of 2 years. Gross total resection (GTR) for PSP is controversial for improving overall survival. However, if the lesion is easily accessible, for example, nonskull base lesion, GTR is still advocated.

Case description

A 67-year-old male patient presented with right occipital neuralgia and diplopia in the last year.
