This imaging procedure (Toshiba Aplio XG, using a curved 3.5-MHz probe) showed intense hyperechoic, homogenous and well-defined nodules in segment VII/VIII (3.1 x 2 cm, 0.9 x 0.6 cm and 0.7 x 0.7 cm), segment V/VI (1.5 x 1.5 cm) and another in the caudate lobe (1.8 x 2.2 cm) (fig. 1).
a MRI of a typical hemangioma in liver segment VIII. T2-weighted imaging showed a bright hyperintense lesion ('light bulb phenomenon'). After injection of contrast, the arterial phase (b) showed a typical rim-like peripheral enhancement with gradual centripetal contrast uptake in the portal-venous phase (c) and in the late phase (d).

The lesions at the aforementioned locations were all confirmed as being hemangiomas without any inflammatory or malignant characteristics (fig. 2).

A follow-up ultrasound at 3 months demonstrated all lesions with a typical hypo- to isoechoic pattern (fig. 3a). These ultrasound images from the referral hospital were available, demonstrating identical sonographic features (fig. 3b) as found after recovering from SIRS and pneumonia.
