Which liver abscess type can present as a mass with internal septations resembling spokes of a wheel in its early stage?

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

Answer: (B)

The ultrasound appearance of a liver abscess varies with the invading organism. In fungal liver abscesses, especially Candida, early disease often forms a mass that contains multiple small loculations separated by thin septa. This creates an internal pattern that resembles spokes of a wheel radiating from a central area of necrosis. The septations reflect these separating compartments within the abscess and are more likely to be evident in the early stage before the lesion becomes a more homogeneous, thick-walled cavity. This pattern helps distinguish fungal involvement from other types. Pyogenic abscesses more often present as irregular, sometimes gas-containing collections with thicker, uneven walls; amebic abscesses tend to be solitary and smoother-walled with fewer internal septations. In a patient with risk factors for fungal infection, seeing a hepatic mass with internal septations in the early stage points toward a fungal etiology.
