Magnetic Resonance Imaging of Sympathetic Ganglion in a Patient with Internal Carotid Artery Dissection

Abstract

Previously, a healthy 41-year-old man presented with
headache that radiated to the right side of the neck and
teeth. Symptoms began 3 days before presentation after
a fall. He had right-sided miosis, ptosis, facial flushing,
and conjunctival injection on examination. CT-angiogra‐
phy showed dissection of the distal cervical right inter‐
nal carotid artery starting at the level of C2 and extend‐
ing to the skull base. Thin-slice high-resolution 3T T1
and T2 weighted fat-saturated magnetic resonance imag‐
ing images showed the intramural hematoma as a cres‐
centic hyperintensity along the medial wall of the vessel,
which was compressing the true lumen and the adjacent
superior sympathetic ganglion.
