Starry sky liver in twin anemia–polycythemia sequence

‘Starry sky’ describes a sonographic pattern seen in diffuse liver pathology, characterized by clearly identified portal venules (stars) and diminished parenchymal echogenicity (sky) that accentuates the portal venule walls1. Starry sky pattern has been reported previously in association with twin–twin transfusion syndrome (TTTS) of the twin oligohydramnios–polyhydramnios sequence (TOPS) type2. Twin anemia–polycythemia sequence (TAPS) is a less common variant of TTTS that does not fulfill the
