[Infrequent complications in a single patient: esophageal perforation, cervical vascular injury, and soft tissue infection caused by a spine].

In this article, we present an exceptionally rare and challenging clinical case. It concerns a 65-year-old woman who, while eating, accidentally ingested a thorn. This foreign body, after being swallowed, migrated from the proximal esophagus, until it penetrated the left internal jugular vein. This unusual phenomenon presented as the main symptom, high dysphagia of acute course, accompanied by a hematoma in the left hemicollar. This case not only highlights the potential seriousness of accidental foreign body ingestion, but also the possibility of migration to potentially serious infrequent locations leading to diagnostic and therapeutic challenges. Foreign body migration through soft tissue and subsequent impact on critical vascular structures are extremely rare events and require immediate and specialized medical intervention.
