Head CT of the pediatric patient. In the CT results of the head from another hospital, a transverse plane through the inferior portion of the parieto-occipital sulcus showed a hypodense shadow next to the posterior horn of the right ventricle (A), and on the 36th day of hospitalization, a transverse plane through the center of the hemioval showed a right parietal hematoma with herniation of the cerebral sickle (B).

A head CT performed at another hospital showed a hypodense shadow next to the posterior horn of the right lateral ventricle (Figure 1A). A CT head examination was completed, which showed a right parietal hematoma and a falciform herniation of the brain (Figure 1B).
Transthoracic echocardiography examination of the heart in the pediatric patient. A striated flocculent hyperechoic attachment (A), was observed at the entrance to the left pulmonary vein in the lateral posterior wall of the left atrium, with thickened anterior and posterior mitral leaflets and a striated flocculent hyperechoic attachment with a floppy texture visible in both anterior and posterior leaflets (B). LA: left atrium; LV left ventricle; RA: right atrium.

Transthoracic echocardiography showed thickening of the anterior mitral valve leaflet with vegetation attachment and vegetation formation at the entrance to the pulmonary veins in the lateral posterior wall of the left atrium (Figure 2).
Contrast-enhanced cranial MRI + MRA of the pediatric patient. The transverse plane through the inferior portion of the parieto-occipital sulcus showed a distal aneurysm of the right middle temporal artery and the right posterior cerebral artery (A), the transverse plane through the superior cerebellar peduncle showed an aneurysm at the tip of the basilar artery and stenosis of the left middle cerebral artery with multiple collateral vessel formation (B,C), and the transverse plane through the superior cerebellar peduncle showed an abdominal cerebral infarction (D).

Contrast-enhanced MRI + magnetic resonance angiography of the head showed aneurysm formation in the right middle temporal artery, distal right posterior cerebral artery and apical region of the basilar artery, cerebral bridge infarction, and stenosis of the left middle cerebral artery with multiple collateral vessel formation (Figure 3).
