Differential Diagnosis for Upper Dental Infection and Sinusitis with Eye Bruise
Single Most Likely Diagnosis
- Odontogenic Sinusitis with Periorbital Cellulitis: This condition is a direct extension of an upper dental infection into the sinuses, potentially causing sinusitis. The eye bruise could be a result of periorbital cellulitis, an infection of the skin and tissues around the eye, which can occur as a complication of sinusitis or direct spread from the dental infection.
Other Likely Diagnoses
- Sinusitis with Orbital Complications: Sinusitis can lead to various orbital complications, including periorbital cellulitis, orbital cellulitis, and abscesses. The eye bruise could be indicative of such complications.
- Dental Abscess with Facial Cellulitis: A dental abscess can spread and cause facial cellulitis, which might involve the area around the eye, leading to bruising and swelling.
- Maxillary Sinusitis: Given the proximity of the maxillary sinus to the upper teeth, an infection in this area could easily spread from a dental source, causing sinusitis symptoms and potentially affecting the eye.
Do Not Miss Diagnoses
- Cavernous Sinus Thrombosis: Although rare, this condition is potentially life-threatening. It can occur as a complication of facial or sinus infections, including those originating from dental infections. Symptoms can include eye findings such as proptosis, chemosis, and ophthalmoplegia, in addition to the potential for bruising.
- Orbital Abscess: An abscess within the orbit can cause severe symptoms, including vision loss, and requires urgent treatment. It can arise from the spread of infection from the sinuses or from a direct extension of a dental infection.
Rare Diagnoses
- Wegener's Granulomatosis (Granulomatosis with Polyangiitis): This is a rare autoimmune disorder that can cause a wide range of symptoms, including sinusitis, eye inflammation, and potentially dental issues due to its systemic nature.
- Sarcoidosis: Another rare condition that can affect multiple parts of the body, including the sinuses and eyes, potentially mimicking an infection or causing similar symptoms.
