 INTRODUCTION: Cryptococcal infections are typically thought of as occurring in immunocompromised patients, such as patients with HIV/AIDS, solid organ transplant recipients, or patients with rheumatologic diseases that require immunomodulatory therapy. Moreover, CASE: The patient is an otherwise healthy 89-year-old male with a past medical history notable only for hypertension who presented with progressive left-sided neck pain that became worse despite lidocaine trigger point injections
  imaging was obtained and revealed a C1-C2 prevertebral abscess, C2-C4 osteomyelitis, and a small C2-C4 abscess. An aspiration biopsy from one of the cervical abscesses grew CONCLUSIONS: Unconventional presentations of cryptococcal disease are becoming increasingly recognized in seemingly immunocompetent patients. Our case was unique given that it occurred in a patient who appeared to be immunocompetent and the Gram stain showed a speckled-egg staining pattern that alone was not distinctive for cryptococcal yeasts. Despite the patient's lack of any classic comorbidities associated with invasive cryptococcal disease, his advanced age was likely a risk factor.
