Objective:
Spinal intramedullary histoplasmosis is an extremely rare condition. We report a case of isolated intramedullary histoplasmosis as the initial manifestation of human immunodeficiency virus (HIV) infection.
Clinical Presentation:
A 27-year-old man presented with a rapidly progressive paraparesis. Magnetic resonance imaging scans revealed an enhancing lesion at C7-T1 with edema extending as far as the cervicomedullary junction. He improved with steroid medications.
Intervention:
The patient underwent laminectomy and biopsy of the lesion. The diagnosis of histoplasmosis was made by histology, culture, and polymerase chain reaction identification of fungal deoxyribonucleic acid. The patient did not have disseminated histoplasmosis. Subsequent to the biopsy, the patient was discovered to have HIV infection.
Conclusion:
The isolated spinal histoplasmosis lesion thus represented the initial presentation of HIV infection. Management of the case and diagnostic issues are discussed.
Insights
This case study highlights an extremely rare instance of spinal intramedullary histoplasmosis presenting as the first sign of human immunodeficiency virus (HIV) infection.
Area of Science:
- Neurology
- Infectious Diseases
- Mycology
Background:
- Spinal intramedullary histoplasmosis is exceptionally rare.
- Histoplasmosis typically affects the lungs but can disseminate.
Observation:
- A 27-year-old man presented with rapid paraparesis.
- MRI revealed a C7-T1 intramedullary lesion with edema.
- Initial treatment with steroids provided partial improvement.
Findings:
- Biopsy confirmed histoplasmosis via histology, culture, and PCR.
- The patient had no signs of disseminated disease.
- HIV infection was diagnosed after the spinal lesion biopsy.
Implications:
- This case demonstrates spinal histoplasmosis as an initial manifestation of HIV infection.
- Early diagnosis and management are crucial for neurological recovery.
- Highlights the importance of considering opportunistic infections in new-onset neurological deficits.
