From: Spontaneous cervical epidural hematoma associated with thunderclap headache
Sagittal pre (a) and post-contrast (b) T1 MRI demonstrate an epidural collection spanning from mid-C2 through T1/T2 vertebral level (white arrow). Axial T1 (c) and T2 (d) MRI demonstrate regions of mixed intensity within the cervical epidural collection (white arrow), suggestive of spontaneous spinal epidural hematoma (SSEH). A rim of contrast enhancement is seen extending from the upper cervical cord to the ventral medulla and anterior pons (b, gray arrow)
