Post-concussive syndrome to primary central nervous system lymphoma: An insidious presentation.
Primary central nervous system lymphoma (PCNSL) and central neurogenic hyperventilation (CNH) are both rare occurrences, especially when associated with Epstein-Barr Virus (EBV). We report a case of an immunocompetent individual who presented to the emergency department (ED) with vague neurological symptoms found to have an EBV-associated PCNSL complicated by CNH. This rare occurrence had an insidious presentation initially mistaken for "post-concussive syndrome" at an outside ED. Insidious neurological malignancies, posterior strokes, intracranial hematomas, and other life-threatening pathologies should always be on the differential in patients presenting to the ED with falls with associated neurological symptoms, especially with unexplained blood gas abnormalities.

Bromism is an unusual syndrome characterized by a variety of nervous system impairments such as ataxia, confusion, and delusions. Contemporaneous cases are rare as therapeutic use of bromide-containing medications has declined, but bromides can still be obtained as unregulated dietary supplements. Bromism from dietary supplements is not well-described. ⋯ He was treated with maintenance intravenous normal saline to promote excretion of the bromide ion and slowly returned to baseline over ten days. Bromism is an unusual but well-described constellation of neurologic impairments that presents insidiously and may be easily missed. The emergency physician should be aware of the dangers of bromide-containing dietary supplements and should educate patients taking these supplements of their risks.
