Neck swelling from a retropharyngeal abscess caused by penicillin-resistant Streptococcus pneumoniae: a case report

Parapharyngeal abscess secondary to lymphovenous malformation

Background

Deep neck space abscesses are an uncommon but life-threatening emergency presentation to the ENT surgeon because of potential acute airway compromise.

Objective

This paper presents a novel case of a palatine tonsillar, low-flow, lymphovenous malformation pre-disposing to multifocal deep neck space collections and resultant acute airway compromise.

Fluid collection in the retropharyngeal space: A wide spectrum of various emergency diseases

Fluid collections in the retropharyngeal space (RPS) result from a wide spectrum of diseases, including retropharyngeal abscess, cervical osteomyelitis, and calcific tendinitis of the longus colli muscle. These conditions should be managed by different specialties; beginning with care in the emergency room, physicians from orthopedics, pediatrics, otolaryngology, and oncology are in charge of the treatment. Since these diseases demonstrate similar fluid collections in the RPS on computed tomography (CT) and magnetic resonance imaging (MRI), the radiologist's diagnosis based on the characteristic imaging findings is very important to identify the primary disease. Also, since some of the diseases require immediate surgical intervention to avoid life-threatening mediastinitis or airway obstruction, radiologists must distinguish these diseases correctly and provide recommendations for their management to physicians. Understanding clinical features and imaging findings of these fluid collections in the RPS is crucial for the best care.
