Non-Hodgkin B-cell Lymphoma Presenting as a Pituitary Mass

Abstract

INTRODUCTION: The authors describe the case of a pituitary mass considered from the radiological point of view as a non-secretory adenoma. CASE REPORT: The patient, a 31-year-old male, presented with an intense headache, non-responsive to antalgics, right eye Mydriasis, and semiptosis. An endoscopic transnasal surgery caused important but temporary relief to the patient, who some days later complained of tumefactions in both axillar regions. Pathological diagnosis was of a non-Hodgkin B-cell lymphoma. CONCLUSIONS: Although pituitary involvement is rare in the case of systemic lymphomas, and even rarer among primary central nervous system malignancies, this possibility must become part of differential diagnosis when approaching pituitary masses.
