An epidural location for lymphoma is observed in 0.1-6.5% of all the lymphomas. Primary spinal epidural lymphoma (PSEL) is a subset of lymphomas, where there are no other recognizable sites of lymphomas at the time of diagnosis. The incidence of this subset of lymphomas is much less. It, however, is increasingly diagnosed, due to the increased use of more sensitive imaging modalities. For the electronic search, Pubmed was used to identify journals that enlisted and enumerated PSEL from 1961 to January 2011. The following combination of terms: "primary," "spinal," "epidural," and "lymphoma" were used. The most significant articles and their bibliographies were analyzed by the authors. The symptoms, pathogenesis, diagnostic workup, histopathology, treatment, and outcome have been analyzed in a systematic manner.

Intracranial schwannomas commonly arise from the eighth cranial nerve in the cerebellopontine angle. Schwannoma arising in the sella and extending into the suprasellar region is very rare and is easily mistaken for pituitary adenoma. To our knowledge, there have been only 12 previous reports. We present a patient with primary intrasellar schwannoma that clinically and radiologically resembled a pituitary adenoma (PA). Intra-operative findings differed from a PA, as the tumour had a firmer consistency. Gross total excision of the lesion was done via a transethmosphenoidal approach. Post-operatively the patient improved in visual acuity and visual fields. We have reviewed the literature and described the characteristics of such lesions. © 2012 Elsevier Ltd.
