Evaluating the pivotal role of MRI in craniocervical junction injury diagnosis: A case report.

RATIONALE

Diagnosing craniocervical junction (CCJ) traumatic injuries at initial evaluation is challenging due to patient noncooperation, pain, and multiple traumas, often leading to missed diagnoses with long-term consequences.

PATIENT CONCERNS

A 35-year-old male with chronic neck pain and neurological symptoms caused by an undiagnosed CCJ injury from a childhood motor vehicle accident.

DIAGNOSES

The initial radiographs showed normal atlanto-dental interval, basion-dense interval, and basion-axial interval measurements. Symptoms prompted a magnetic resonance imaging (MRI), which revealed a missed hematoma deep to the tectorial membrane, exerting pressure on the cervical cord, along with ligamentous injuries, confirming chronic compression causing myelomalacia and cervical cord atrophy, and atlantoaxial instability from a ruptured apical ligament.

INTERVENTIONS

Over 5 years of conservative treatment (physical therapy, pain management) failed to relieve symptoms. Post-MRI, management shifted to neurosurgical and orthopedic consultations, with consideration of surgical stabilization.

OUTCOMES

Prolonged conservative treatment was ineffective due to undiagnosed injuries, resulting in persistent symptoms and neurological deficits. Delayed MRI diagnosis limited outcomes, with management focused on stabilizing the CCJ to prevent further deterioration.

LESSONS

Radiographs and computed tomography are limited in detecting CCJ soft tissue injuries. MRI is essential for identifying hematomas and ligament damage in high-velocity trauma, enabling timely intervention to prevent long-term neurological complications.
