Hematoma subdural espinal espontáneo: hallazgos en resonancia magnética a propósito de dos casos

The most significant MRI findings in the hyperacute phase were isointense signal on T1-weighted sequences and hyperintense signal on T2-weighted sequences. Moreover, T2-weighted gradient-echo sequences showed a hypointense peripheral ring. In the subacute phase, a hyperintense signal was seen on T1-, T1-fat-suppression, and T2-weighted sequences.
