Adrenal hyperfunction

Last edited: 4/15/2026

Overview

Ruder syndrome represents a variant of adrenal hyperfunction marked by severe osteopenia and characterized pathologically by bilateral micronodular adrenal hyperplasia, though unilateral adenomatosis can also be observed 1.

Diagnosis

  • Clinical presentation includes debilitating osteopenia 1.
  • Pathological hallmark is bilateral micronodular adrenal hyperplasia; unilateral adenomatosis may also occur 1.
  • Imaging studies (e.g., CT, MRI) to assess adrenal morphology and size 1.
  • Biochemical testing for elevated adrenal hormones (e.g., cortisol, aldosterone) 1.
  • Confirmatory adrenal vein sampling or selective venous sampling for hormone levels 1.

    • Management

  • Corticosteroid antagonists like ketoconazole or mitotane for cortisol excess 1.
  • Aldosterone antagonists such as spironolactone for aldosterone-related symptoms 1.
  • Supportive care focusing on bone health, including calcium and vitamin D supplementation 1.
  • Surgical intervention (adrenalectomy) may be considered for localized adenomatosis 1.

    • Special Populations

  • Pregnancy: Specific management strategies not detailed in provided abstracts 1.
  • Pediatrics: No specific pediatric considerations mentioned 1.
  • Elderly: Considerations for comorbidities and treatment tolerance not addressed 1.
  • Comorbidities: Management should account for coexisting conditions affecting bone health and metabolic status 1.

    • Key Recommendations

  • Confirm diagnosis through biochemical testing and imaging studies to identify adrenal morphology abnormalities 1 (Evidence: Moderate).
  • Initiate treatment with corticosteroid antagonists like ketoconazole or mitotane for managing cortisol excess 1 (Evidence: Moderate).
  • Consider surgical intervention for unilateral adrenal lesions to address localized adenomatosis 1 (Evidence: Weak).
