Which liver abscess type may appear as a uniformly hypoechoic mass with calcifications indicating late-stage disease?

• A. Pyogenic
• B. Candidiasis
• C. Fungal
• D. Amebic

Answer: (C)

When an abscess in the liver becomes chronic, calcifications can form as part of the body's long-standing inflammatory and granulomatous response. Fungal (Candida) liver abscesses are known for necrotic, fluid-filled interiors that can appear as uniformly hypoechoic masses on ultrasound. As these lesions age, dystrophic calcifications may develop within the lesion or its capsule, giving a pattern of a predominantly dark (hypoechoic) mass with calcified foci. This combination—a uniformly hypoechoic lesion with calcifications indicating late-stage disease—fits fungal liver abscess most closely. Pyogenic abscesses are typically more complex, with internal echoes, septations, and sometimes gas; amebic abscesses are often solitary and may show posterior enhancement without the characteristic calcifications of chronic fungal lesions.
