Clivus lymphoma

摘要

Lymphoma as primary infiltration of the skull base, especially the clivus, is unusual and rare [1, 2, 4, 5]. However, increasing incidence of atypical lymphoma manifestations have been reported [5]. As cranial base surgery becomes more common, it is important to be aware of lymphoma as a possible differential diagnosis of clivus lesions. This case presents a primary malignant lymphoma of the clivus, histologically confirmed after intra-operative MRI-guided transnasal-transsphenoidal biopsy.
