case_images: Right-sided ptosis observed two (a) and in somewhat lesser extent six (b) hours after selective C7 nerve. root. block. Tip of the cannula positioned under computed tomographic guidance at the outer confines of the right-sided neuroforamen C6/C7 to perform selective C7 nerve root block (c). Post-procedure control showed distribution of the contrasted mix of local anesthetic and non-crystalloid corticosteroid alongside the C7 root and into the transverse foramen (arrow in d), as well as into the epidural space (arrow in e). Note the reversal sides in the images due to the patient being in the prone position. The Asterisk * marks vertebra C6
