Figure 2
Patient presented with moyamoya disease. (a) Echocardiography with normal findings at the time of the first attack. (b) Brain MRI showed multiple new lesions in the left brain and bilateral cerebellum (arrow) at the first attack. (c) MRA revealed occlusion of the middle cerebral artery (arrow). (d) Echocardiography revealed a highly mobile mass attached to the fossa ovalis (arrow) at the second attack. (e) The second MRI showed a haematoma (dotted arrow) in the left basal ganglia and new infarction lesions in the left cerebral peduncle. (f) DSA showed occlusion of the middle cerebral artery (arrow) and secondary formation of an unusual vascular network (not shown). (g) After surgery, echocardiography showed that the mass in the left atrium had disappeared. (h) CT showed a stroke capsule in the left brain (arrow). (i) Histopathology showed spindle (dotted arrow) and stellate mesenchymal cells (arrow) that were embedded in the myxomatous stroma.
