Highly Active Antiretroviral Therapy and Gamma Knife Radiosurgery for the Treatment of AIDS-Related Primary Central Nervous System Lymphoma.

Background: The criterion standard for the treatment of newly diagnosed primary central nervous system lymphoma (PCNSL) remains high-dose chemotherapy in conjunction with palliative whole-brain radiotherapy; however, there may be a role for novel combined approaches in immunocompromised patients.

Case Description: A 66-year-old man presented with acute cephalalgia, disorientation, and lethargy. His condition was evaluated in the emergency department, and he was admitted with probable hydrocephalus.

A case report and technical tip of chronic subdural hematoma treated by the placement of a subdural peritoneal shunt.

Background: Chronic subdural hematomas (CSDH) tend to occur most commonly in the elderly population, usually resulting from minor or insignificant head trauma. The pathophysiology behind CSDH is often directly associated with cerebral atrophy, and other causes of cerebral atrophy such as alcoholism or dementia. Other predisposing factors include diabetes, coagulopathy, use of anticoagulants (including aspirin), seizure disorders, and CSF shunts.

Comparison of Percutaneous Retrogasserian Balloon Compression and Gamma Knife Radiosurgery for the Treatment of Trigeminal Neuralgia in Multiple Sclerosis.

Objective: We compared and evaluated percutaneous retrogasserian balloon compression (PBC) and Gamma Knife radiosurgery (GKRS) for treatment of trigeminal neuralgia (TN) in patients with multiple sclerosis (MS).

Methods: In this single-center, retrospective comparative study, 202 patients with MS and concomitant TN were evaluated. A minimum follow-up of 24 months was required.

Primary Central Nervous System Lymphoma (PCNSL): Analysis of Treatment by Gamma Knife Radiosurgery and Chemotherapy in a Prospective, Observational Study.

Background: Primary central nervous system lymphoma (PCNSL) is a rare cancer accounting for less than 3% of primary brain and central nervous system (CNS) tumors. Tissues involved include the brain parenchyma, leptomeninges, eyes, and spinal cord. High-dose methotrexate (MTX) is the gold standard for newly diagnosed PCNSL.
