Delayed development of neurological deficit from an occipital fracture. A case report

Collet-Sicard syndrome: a scoping review

Collet-Sicard syndrome (CSS) is the unilateral palsy of the cranial nerves (CN) IX, X, XI, and XII. To our knowledge, no review describes the characteristics of patients diagnosed with CSS. Therefore, this review aims to collect and describe all cases in the literature labeled as CSS. We performed a scoping review of the literature and conducted a database search in Embase and PubMed. We included articles and abstracts with case reports or case series of patients with CSS diagnosis. We classified the cases into two groups: "CSS", referring to patients presenting exclusively with IX-XII nerve involvement, and "CSS-plus", which corresponds to cases with CSS and other neurological impairments. We included 135 patients from 126 articles, of which 84 (67.7%) were male. The most common clinical manifestations reported were dysphagia and dysphonia. The most common etiology was tumoral in 53 cases (39.6%) and vascular in 37 cases (27.6%). The majority of patients showed partial or total improvement, with just over half receiving conservative treatment. The most frequent anatomic space was the jugular foramen (44.4%) and the parapharyngeal retrostyloid space (28.9%). Approximately 21% of the patients had other CN impairments, with the seventh and eighth CN most frequently compromised. We conclude that although there is a need for greater rigor in CSS reporting, the syndrome has a clear utility in identifying the localization of jugular foramen and parapharyngeal retrostyloid space pathology.

Occipital condyle fracture in a patient with neck pain

Background

Occipital condyle fractures (OCF) are rare traumatic injuries and are of critical clinical importance because of the anatomic considerations of the occipitoatlantoaxial joint complex. OCF can be a diagnostic challenge because of the inability to diagnose this injury with plain radiographs. This is especially true in the emergency department (ED) setting. A high degree of clinical suspicion and careful investigation of the craniocervical junction is warranted in patients presenting to the ED with head and cervical trauma.

Findings

We present a case of a 45-year-old male who presented to the ED with complaints of neck pain and headache four days after an assault. The classification, clinical presentation, diagnosis, and management of his injury are discussed, and pertinent literature is reviewed.

Conclusions

OCF can be easily overlooked due to multiple factors; including the conscious state of the patient or the inability to diagnose it through plain radiographs. Early recognition and diagnosis of OCF is crucial to prevent neurological involvement.
