Summary

Central nervous system (CNS) cryptococcal infection often presents with headache. MRI scans detect more lesions than CT scans, and fluconazole shows promise for chronic oral therapy in cryptococcosis.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Radiology

Background:

  • Cryptococcal infections can affect the central nervous system (CNS).
  • Clinical presentation is often dominated by severe headache.
  • Complications include meningitis, granulomas, and hydrocephalus.

Observation:

  • Headache was the most common symptom in all eleven patients.
  • CT head scans demonstrated intracranial cryptococcal granulomas and hydrocephalus.
  • MRI scans revealed additional parenchymal lesions not visible on CT.

Findings:

  • Combined amphotericin B and 5-fluorocytosine is the standard treatment.
  • Fluconazole was used in three patients, showing potential for chronic oral therapy.
  • One patient with refractory disease responded well to chronic oral fluconazole.

Implications:

  • Early diagnosis and appropriate imaging (MRI) are crucial for CNS cryptococcosis management.
  • MRI offers superior detection of parenchymal lesions compared to CT.
  • Fluconazole represents a viable option for long-term management, particularly in refractory cases.
