Classical histoplasmosis mediastinal fibrosis

Last edited: 4/15/2026

Overview

Classical histoplasmosis mediastinal fibrosis is a complication of histoplasmosis characterized by fibrous thickening of the mediastinum, often complicating diagnostic and therapeutic procedures due to anatomical constraints 1.

Diagnosis

  • Imaging studies (CT, MRI) essential for identifying mediastinal fibrosis 1.
  • Mediastinoscopy recommended for definitive diagnosis and to assess extent of fibrosis 1.
  • Histopathological examination of biopsy samples crucial for confirming Histoplasma infection 1.

    • Management

  • No specific drug dosing mentioned for mediastinal fibrosis; antifungal therapy (e.g., amphotericin B, itraconazole) guided by systemic histoplasmosis treatment protocols 1.
  • Surgical intervention may be required for complications or diagnostic purposes, with re-mediastinoscopy feasible if diagnostic yield is anticipated 1.

    • Special Populations

  • No specific guidance provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.

    • Key Recommendations

  • Perform mediastinoscopy if it can contribute significantly to diagnosis despite existing mediastinal fibrosis 1 (Evidence: Moderate).
  • Consider re-mediastinoscopy in cases where further diagnostic evaluation is necessary despite prior fibrosis 1 (Evidence: Expert opinion).
  • Tailor antifungal therapy based on systemic involvement rather than fibrosis severity alone, consulting specific antifungal guidelines 1 (Evidence: Expert opinion).
