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

Object:The objective of the present study is to analyze the complications and their avoidance in a series of 80 patients operated by transcallosal transforaminal approach to colloid cysts of the anterior third ventricle.Materials and Methods:The surgical outcome and complications of 80 patients operated by transcallosal transforaminal approach for colloid cysts in the anterior third ventricle was analyzed. A detailed pre- and post-operative neurological assessment was done in all patients. Neurocognitive assessment of corpus callosal function was done in the last 22 cases. CT scan of the brain was done in all patients, before and after surgery.Results:All patients underwent transcallosal transforaminal approach. Total excision of the lesion was achieved in 79 patients and subtotal in one. The complications encountered were postoperative seizures in six, acute hydrocephalus in four, venous cortical infarct in four, transient hemiparesis in four, transient memory impairment, especially for immediate recall in nine, mutism in one, subdural hematoma in one, meningitis in three, and tension pneumocephalus in one patient. There were two mortalities. There was no incidence of postoperative disconnection syndrome.Conclusion:Colloid cyst is surgically curable. With good knowledge of the regional anatomy and meticulous microsurgical techniques, there is a low mortality and minimum morbidity, when compared to the natural history of the disease. With increasing experience, most of the complications are avoidable. The limited anterior callosotomy does not result in disconnection syndromes.
