Discharge Summary

Patient Name: Not provided            Medical Record Number: Not provided
Discharge Date: Not provided            Discharge Diagnosis: CNS vasculitis secondary to Cryptococcus neoformans variant infection

History of Presenting Illness:
The patient is a 35-year-old woman with a history of having lived near a pigeon farm who presented with one month of progressive neurological symptoms, including headache, vomiting, blurred vision, bradypsychia, vertigo, aphasia, gait instability, and right-sided paresthesia and weakness. During admission, the patient presented with a generalized tonic-clonic seizure. An LP revealed an elevated open pressure, increased cell count with predominant lymphocytes, low glucose, and high protein. India ink preparation and cryptococcal antigen test were positive. 

Hospital Course:
The patient was started on treatment with liposomal amphotericin B, flucytosine, levetiracetam, and medprednisone. Mycological culture was positive for Cryptococcus neoformans variant. An extensive analysis to rule out immunocompromised status was performed. Cancer screening was done, which did not show any positive results. MRI showed hydrocephalus, bilateral cerebellar lesions with increased signal, and a focal lesion on the right-side gyrus of the cingulum in relation to the peak of the corpus callosum. Digital subtraction angiography confirmed CNS vasculitis. After 30 days of treatment with amphotericin B and flucytosine, it was changed for fluconazole 400 mg for 10 weeks more, with good clinical response.
 
One-year follow-up:
The patient showed an expressive improvement of laboratory findings, mild ataxia, tinnitus, and mild right hypoacusia. However, the patient has diminished bilateral visual acuity and hydrocephalus. Vestibular myogenic evoked potentials showed involvement of the vestibular-spinal pathway. The patient is now on vestibular rehabilitation and is being evaluated for a cochlear implant.
