A patient presented with bilateral... Cheeks swelling, with swelling at the neck region also. Associated with? Severe pain, odynophagia. Dysfezjia. And mild SOB. Patient was normal six days back. She developed mild left tooth pain. Which increased... And leaded to swelling at the left cheek. Which... Extended towards the neck and then towards the right cheek. Now the patient is severely in pain. Uh, and she has the mouth discharge with a lot of smell. But she discharge from the mouth, which she's spitting out of her mouth in every twen- 10 to 20 minutes. What could be the reasons of this condition? What can be the differential diagnosis? And what could be the infection associated with this condition? Coccidioidomycosis. Or mumps. Is the mum patient has no fever history.

This presentation is most concerning for a rapidly spreading odontogenic deep neck-space infection, particularly Ludwig angina, arising from an infected lower molar or dental abscess.
This is an airway emergency. Mild shortness of breath, dysphagia/odynophagia, inability to manage frequent foul oral secretions, progressive neck swelling, and severe pain can deteriorate quickly. She needs immediate emergency-department transfer by ambulance, with urgent ENT/oral-maxillofacial surgery and anesthesiology assessment. Do not manage this as an outpatient dental infection.

Most likely explanation

A dental infection, often from a mandibular molar, can spread from the tooth root into the:
  • Submandibular space
  • Sublingual space
  • Submental space
  • Then across the midline and posteriorly into parapharyngeal/retropharyngeal spaces
Bilateral hard, tender floor-of-mouth/submandibular swelling with tongue elevation and airway symptoms is the classic pattern of Ludwig angina. It can cause airway obstruction from posterior tongue displacement. Rosen's Emergency Medicine, p. 961; Rosen's Emergency Medicine, p. 864.

Important differentials

  1. Ludwig angina / bilateral submandibular cellulitis from a lower-tooth infection - leading diagnosis.
  2. Odontogenic abscess with spread to buccal, submandibular, sublingual, or masticator spaces.
  3. Parapharyngeal or retropharyngeal abscess - especially if there is neck stiffness, voice change, trismus, or worsening breathing.
  4. Peritonsillar abscess - typically unilateral severe throat pain, trismus, muffled "hot-potato" voice, and uvular deviation.
  5. Acute suppurative sialadenitis or submandibular/parotid abscess - possible, but the initial tooth pain and progressive spread strongly favor a dental source.
  6. Necrotizing soft-tissue infection - consider if pain is extreme/out of proportion, there is skin discoloration, crepitus, toxicity, or rapid progression.
  7. Angioedema - can swell face/neck but does not explain preceding toothache, foul purulent oral discharge, and progressive infective symptoms.
  8. Malignancy with secondary infection - less likely in this rapid 6-day course, but considered after acute stabilization if atypical.

Likely infecting organisms

This is usually polymicrobial oral flora, not a single organism:
  • Viridans-group streptococci and other oral streptococci
  • Anaerobes: Prevotella, Porphyromonas, Fusobacterium, Peptostreptococcus
  • Sometimes Staphylococcus aureus
  • In certain severe neck infections, Fusobacterium necrophorum is relevant because of Lemierre syndrome risk
The foul-smelling discharge is especially compatible with anaerobic dental infection. The infection may be cellulitis initially, but a drainable abscess can develop.

Why mumps and coccidioidomycosis are unlikely

  • Mumps typically causes parotid-gland swelling, often bilateral, and is viral. It does not usually begin with focal tooth pain or cause foul purulent oral discharge, marked progressive submandibular/neck spread, or this degree of airway concern. Lack of fever does not exclude infection, but mumps is not the leading diagnosis here.
  • Coccidioidomycosis is a fungal infection acquired by inhalation, usually causing a respiratory syndrome. It is not a typical cause of acute tooth-origin facial and deep-neck swelling.

Immediate priorities in hospital

  • Airway assessment first: drooling, dyspnea, stridor, inability to lie flat, voice change, tongue elevation, and inability to swallow secretions are red flags.
  • IV access, fluids, analgesia, and broad-spectrum IV antibiotics covering oral streptococci and anaerobes.
  • Urgent ENT/maxillofacial surgery review for source control, including drainage when appropriate and treatment/extraction of the infected tooth.
  • Contrast CT of the neck is useful to define deep-space extension or an abscess only if it does not delay airway protection. Rosen's Emergency Medicine, p. 961.
  • Monitor for mediastinal spread, sepsis, jugular-vein thrombophlebitis, and airway obstruction. Deep neck infections may require surgical drainage and treatment of the causative tooth. Mulholland and Greenfield's Surgery, p. 1975.
Absence of fever is not reassuring in this case. Given shortness of breath and secretion handling difficulty, she should be treated as having impending airway compromise until assessed in an emergency setting.
