Pediatric Stroke: Clinical Findings and Radiological Approach
Figure 3
A 5-year-old male with sudden onset of visual defect followed by generalized seizures without previous hepileptic history. (a) Plain CT scan showing grossly calcified extracerebral occipital mass with loss of brain tissue. (b) MRI T1-weighted image shows typical “salt and pepper” mixed signal in the mass. (c) MRI T2-weighted Turbo Spin Echo image shows the same mass with features indicating hemosiderine rim and different stages of blood clot. (d) MRI T2∗-weighted Fast Field Echo image confirms susceptibility sensitive signal consistent with blood degradation products and different stages of bleeding. All MRI features suggested the diagnosis of giant, mostly extracerebral cavernoma, surgically confirmed.
