Migrating fishbone embedded in the prevertebral soft tissue

Discussion:

Fish bones are one of the most commonly ingested foreign bodies encountered in the upper aerodigestive tract region. Owing to its trivial size, smooth surface, and sharp ends, fish bones have a great propensity to migrate in the neck and adjoining structures. Long standing migrated fishbone can cause devastating complications like neck abscess and injuries to the adjacent structures.

A careful history and a detailed clinico-radiographic investigation is helpful to locate the bone and aided in successful removal.

Herein, we report a case of ingested fish bone, which migrated and embedded in the prevertebral soft tissue. Laryngoscopy and esophagoscopy were performed but the fishbone was not found. Based on the CT findings, neck exploration and removal of the fishbone was performed. During the exploration, the fishbone was at the right side of the posterior pharyngeal wall and embedded in the paraspinal muscle. Minimal pus was surrounding the fishbone.
