Abstract:
Human infection with Histoplasma capsulatum runs the gamut from asymptomatic to disseminated disease. CT-directed fine-needle aspiration of bilaterally enlarged adrenal glands has been used in diagnosing serious infections with this ubiquitous organism. Three cases have previously been reported in which H. capsulatum infection caused unilateral adrenal enlargement; this enlargement was diagnosed post-mortem. We describe three patients with unilateral adrenal enlargement due to H. capsulatum whose conditions were diagnosed antemortem. We encourage clinicians to include infection with H. capsulatum as well as other granulomatous diseases and tumors in the differential diagnosis of unilateral adrenal enlargement.
Insights
Histoplasma capsulatum can cause adrenal gland enlargement. This study highlights three cases of unilateral adrenal enlargement due to Histoplasma capsulatum diagnosed antemortem, expanding diagnostic considerations.
Area of Science:
- Infectious Diseases
- Radiology
- Endocrinology
Background:
- Histoplasma capsulatum is a fungus causing a spectrum of human infections.
- Adrenal gland involvement in Histoplasma capsulatum infection can range from asymptomatic to disseminated disease.
- Diagnosis of serious Histoplasma capsulatum infections often involves CT-guided fine-needle aspiration of enlarged adrenal glands.
Observation:
- Previously, unilateral adrenal enlargement due to Histoplasma capsulatum was only reported post-mortem.
- This study presents three cases of unilateral adrenal enlargement caused by Histoplasma capsulatum.
- These cases were diagnosed antemortem, allowing for timely intervention.
Findings:
- Histoplasma capsulatum can manifest as unilateral adrenal enlargement.
- Antemortem diagnosis of unilateral adrenal enlargement due to Histoplasma capsulatum is achievable.
- CT-guided fine-needle aspiration is a key diagnostic tool.
Implications:
- Clinicians should consider Histoplasma capsulatum in the differential diagnosis of unilateral adrenal enlargement.
- Expanding the differential diagnosis may improve patient outcomes for Histoplasma capsulatum infections.
- This finding aids in the early detection and management of fungal infections affecting the adrenal glands.

Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids.

Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
