Purpose:
We report a presumptive case of bilateral placoid choroiditis secondary to disseminated Cryptococcus neoformans infection and review the literature on choroidal involvement of C neoformans.
Methods:
A case report is presented.
Results:
A 35-year-old HIV-positive man presented with disseminated cryptococcal infection. Cryptococcal meningitis was confirmed by lumbar puncture, and skin involvement was confirmed by microscopy of scrapings from a papular, umbilicated, ulcerated lesion. Ophthalmologic examination revealed intact visual acuity, clear vitreous, and multiple yellowish, placoid-appearing choroidal lesions in the posterior pole bilaterally.
Conclusions:
Multifocal choroiditis caused by C neoformans is an uncommon manifestation of disseminated infection, and placoid yellowish choroidal lesions are an unusual variant. These findings must be differentiated from choroidal tuberculosis and other infections. Multifocal choroiditis typically occurs in AIDS patients and may precede the presentation of meningitis. In such patients, choroidal lesions warrant investigation for systemic, life-threatening opportunistic infections.
Insights
This case report details a rare instance of placoid choroiditis caused by disseminated Cryptococcus neoformans infection in an HIV-positive individual. Early identification of these ocular findings is crucial for diagnosing systemic opportunistic infections.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Mycology
Background:
- Disseminated Cryptococcus neoformans infection can manifest with ocular complications.
- Choroidal involvement by C. neoformans is uncommon, with placoid lesions being a rare presentation.
- Ocular findings may precede neurological or dermatological symptoms of cryptococcosis.
Observation:
- A 35-year-old HIV-positive male presented with disseminated cryptococcosis, including meningitis and skin lesions.
- Ophthalmologic examination revealed bilateral placoid choroidal lesions in the posterior pole.
- Visual acuity remained intact despite the presence of significant choroidal pathology.
Findings:
- The case presents a presumptive diagnosis of bilateral placoid choroiditis secondary to disseminated Cryptococcus neoformans.
- This represents an unusual variant of multifocal choroiditis caused by C. neoformans.
- Differential diagnosis must exclude other infectious etiologies like choroidal tuberculosis.
Implications:
- Placoid choroidal lesions in HIV-positive patients warrant investigation for systemic, life-threatening opportunistic infections.
- Early recognition of ocular cryptococcosis can aid in the timely diagnosis and management of disseminated disease.
- This case highlights the importance of a comprehensive ophthalmologic evaluation in immunocompromised patients with suspected systemic infections.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
