Long-term clinical outcome of minimally invasive versus open single-level transforaminal lumbar interbody fusion for degenerative lumbar diseases: a meta-analysis.

Background Context: Minimally invasive surgical transforaminal lumbar interbody fusion (MIS-TLIF) was developed in addition to open-TLIF to minimize iatrogenic soft-tissue damage. A potential disadvantage of MIS-TLIF is inadequate visualization, which may lead to incomplete neural decompression and a less robust arthrodesis. This may cause long-term problems and result in decreased patient satisfaction.

Infection or Glioma? The False Dilemma of Primary Central Nervous System Histiocytic Sarcoma.

Background: Primary central nervous system (CNS) histiocytic sarcoma is an extremely rare lymphoproliferative disorder that affects the CNS and behaves aggressively. Only 27 cases of primary CNS histiocytic sarcoma have been reported. The paucity of literature on this entity has made diagnosis and treatment difficult both for the surgeon and the pathologist.
