Primary large B-cell lymphoma involving the cerebellopontine angle: a case report


Int J Clin Exp Pathol. 2020 Oct 1;13(10):2612-2614. eCollection 2020.


Primary large B-cell lymphomas involving the cerebellopontine angle (CPA) are uncommon. Fewer than 20 cases of large B-cell lymphoma at the CPA have been reported worldwide. Herein, we report a rare case of B-cell lymphoma in a 67-year-old woman who presented with dysphagia and dizziness and showed a lesion involving the right CPA on magnetic resonance imaging (MRI). The primary diagnosis was metastatic tumor; however, postoperative pathology confirmed a diffuse large B-cell lymphoma. The

initial symptoms were resolved completely at the 2-month postoperative follow-up, and the postoperative course was uneventful. Large B-cell lymphoma should be included in the differential diagnosis of CPA lesions.
