RESUMO
Pseudomonas luteola (P. luteola), or Chryseomonas luteola, is an organism rarely reported as a human pathogen of concern. Commonly missed due to its rarity, emerging literature has shown its potential for pathogenicity; therefore, increased vigilance must always be observed in dealing with these bacteria, especially in immunocompromised patients and those with indwelling catheters, foreign bodies, and prosthetic implants. We present a case of a patient who came in for a persistent headache, found to have meningitis, and ended up with cerebral venous sinus thrombosis (CSVT) on further investigation. Interestingly, the patient did not have any other medical conditions, nor did he have any indwelling catheters or foreign bodies. After an extensive literature review, we report the first case of CSVT caused by P. luteola meningitis in an immunocompetent patient, and we aim to shed light on the diagnosis and treatment approach in this unusual case.
