Primary extranodal lymphoma is a common malignant tumor of head and neck but rarely presents in lateral skull base. We reported such a case of lymphoma categorized as diffuse large B-cell lymphoma (DLBCL) subtype in a 74-year-old Chinese female. She has experienced an acute course of continuously trigeminal neuralgia and Horner's syndrome. The lesion was diagnosed as trigeminal schwannoma based...

Extranodal natural killer cell (NK) T lymphoma (ENKL) is a rare type of non Hodgkins lymphoma, accounting for 5% 10% total NHL cases.

OBJECTIVES The aim of this study is to evaluate the role of PET-CT in identification of different patterns of extranodal involvement in Hodgkin's disease (HD) and Non-Hodgkin's Lymphoma (NHL) and to enlist the common sites of extranodal involvement in each histological type and compare our results with the existing literature. METHODS In this retrospective study of 281 cases of lymphomas of v...
