CT scan may show show hypertrophy of esophageal muscle wall
Pseudoachalasia
Dysphagia
Weight loss
Lymphadenopathy
Appetite changes
Cachexia
Older patients
Underlying malignancy that mimics idiopathic achalasia.
Patients tend to be older, duration of symptoms shorter, and weight loss greater and more rapid.
More marked mucosal irregularity
Temporary patency of LES
Endoscopy with biopsy is the most accurate test for diagnosis and tumor histology. It may be used to depict:
Esophageal obstruction
Staging of disease
Gastroscopic biopsy of gastroesophageal junction and cardia may demonstrate malignancy.
Findings at endoscopy, barium swallow, and manometry may be indistinguishable from achalasia.
Chagas disease
Dysphagia
Toxic megacolon
Myocarditis
Blepharitis
Esophageal dilatation
Stasis of barium
Dilated esophagus
Thickened LES (muscular ring)
Giemsa stain will show Trypanosoma cruzi.
PCR may be done to determine trypanosome subtype
Pharyngitis
Dysphagia
Fever
Throat pain
Normal
Inconclusive
Rapid antigen detection test positive for group A streptococccus
Tonsillar hypertrophy may cause severe narrowing of the pharynx
Physical exam may show:
Erythema, edema and/or exudates of the pharynx
Lymphadenopathy
Esophageal candidiasis
Dysphagia
Immunocompromised
History of corticosteroid
Shaggy" appearance (plaques)
Irregular contours in the lower third
Ulceration
Plaques and pseudomembranes
Tiny nodules, polypoid folds (advanced cases)
Creamy white or yellowish plaques (thrush) in oropharynx
Stroke
Progressive dysphagia
Dysarthria
Limb weakness
Fatigue
Pooling of contrast in the pharynx
Aspiration of barium contrast into the airway.
Reduced opening of upper esophageal sphincter
Reduced larynx elevation
CT without contrast is the best initial test to differentiate between ischemic and hemorrhagic stroke
MRI is more specific and sensitive than a CT scan but is more time consuming.
Plummer-Vinson syndrome must be differentiated from other causes of dysphagia, odynophagia and food regurgitation such as GERD, esophageal adenocarcinoma and esophageal stricture.
Esophagogastroduodenoscopy findings include a dilated esophagus with residual food fragments, normal mucosa and occasionally candidiasis (due to the prolonged stasis).
Barium swallow shows the characteristic bird's beak appearance.
