Rapid-involuting hemangioma (RICH) in a newborn. Ultrasound depicted a heterogeneous, fully developed mass invading large parts of the right liver lobe (a) with no flow-signal on Doppler ultrasound (b). MRI showed a rather homogeneous mass (c, d) with uniform enhancement after gadolinium administration (e). The tumor did not increase in size after birth and at the age of 8 months had decreases from 3.7 cm in maximum diameter at birth to 2.0 cm without the need for surgical or interventional treatment
