[Primary Meckel's cave lymphoma. A case and review of the literature]

A rare case of Meckel's cavity lymphoma is presented. Only two other cases of identical localization have been presented in the literature. The symptoms consisted of sensorimotor impairment of the Vth nerve associated with slight exophthalmos. C.T. scan showed a hyperdense lesion in Meckel's cavity. After total surgical removal, histological analysis diagnosed a B-lymphocyte non-Hodgkin's lymphoma. The patient received both radiotherapy and chemotherapy and at one year follow up, the clinical course was good. The lesion had no clinical or radiological specificity. Its prognosis appears to be identical to that of other intracranial lymphomas.
