Sequential MRI of patient with Kaposiform haemangioendothelioma. Initial axial MR images a of 2016 show cortical destruction, marrow oedema involving tibia (T) and fibula (F) with surrounding soft tissue oedema on T1 (left) as well as STIR (right) sequences. Subsequently performed MRI in 2017 reveals increase in calf diameter and marrow oedema in both bones with visualization of plaque like hyperintensity along the muscle plane on STIR images (arrows in b). The recent MR images demonstrate trans-compartment involvement of skin (arrow in c) as thickening and hyperintense signal intensity; subcutaneous plane as fat proliferation which shows reticular pattern/lymphedema; muscles as atrophy and fat proliferation within the intermuscular plane and bones with marrow signal alteration. The similar changes are also evident on T1 weighted sagittal images of 2016 (arrow in d) and 2018 (asterisk in e)
