Spontaneous spinal subdural hematoma is an uncommon finding. This report of two cases of spinal subdural hematoma (one hyperacute and one subacute) discusses the current theory of how it develops, the MRI findings, its differentiation from spinal epidural hematoma, and the value of MRI in monitoring patients undergoing conservative treatment. 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.

El hematoma subdural espinal espontáneo es un hallazgo poco frecuente. En este artículo, a propósito de dos casos de hematoma subdural espinal (hiperagudo y subagudo), se describe la teoría actual del desarrollo del hematoma subdural espinal espontáneo, sus hallazgos en la resonancia magnética, su diferenciación del hematoma epidural espinal y el valor de la resonancia magnética en la monitorización de pacientes en los cuales se decidió un tratamiento conservador. Los hallazgos de la resonancia magnética más destacados eran en la fase hiperaguda una señal isointensa en las secuencias T1 e hiperintensa en T2. Además en las imágenes de eco de gradiente ponderadas en T2 se observó un anillo periférico hipointenso. En la fase subaguda se veía una señal hiperintensa en las secuencias T1, T1 con supresión grasa y T2
