Abstract: Dumbbell spinal tumors get their hourglass or dumbbell shape from being constricted in the middle, with
one part inside the spinal canal and the other extending outside of it.
This is the case of a 37-year-old female who presented to the clinic with a left cervicobrachialgia and
acroparesthesia. While radiographic imaging initially reported a well-defined dumbbell-shaped C7-T1
foraminal tumor consistent with a neurinoma, the pathology report obtained after surgical intervention came
back positive for Ewing’s sarcoma, with no other locations of the tumor. The diagnosis was unexpected
given the shape of the tissue and the rarity of the extraskeletal form of Ewing’s sarcoma (EES). Only 4
previous cases to date have identified a primary cervical dumbbell-shaped extraskeletal Ewing’s sarcoma
in adults.Keywords: Dumbbell, ewing, sarcoma, cervical
