Overview

There are no other imaging findings associated with [disease name].

OR

[Imaging modality] may be helpful in the diagnosis of [disease name]. Findings on an [imaging modality] suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].

Other Imaging Findings

Benign strictures can be distinguished from malignant strictures based on barium esophagography:

• Benign:concentric narrowing, smoothly tapering,
• Malignant: eccentric narrowing, abrupt, asymmetric ,

due to different causes

Barium esophagography is helpful in the diagnosis esophageal stricture. Findings on a barium esophagography suggestive of esophageal stricture include:

	Barium swallowing finding
Gastroesophageal Reflux Disease	Sacculations Fixed transverse folds Esoophageal intramural pseudodiverticula
Esophageal carcinoma	Irregular contour and shelflike proximal and distal margins
Scleroderma	Tapered narrowing in long segment of the distal esophagus
Nasogastric intubation	Long segment of narrowing in the distal esophagus
Radiation stricture	Smooth, tapered segment of concentric narrowing
Drug-induced stricture	Asymmetric focal narrowing in the upper thoracic esophagus
Esophageal sclerotherapy	Long, irregular stricture in the distal esophagus
Caustic ingestion	Segmental or diffuse strictures

• Endoscopic ultrasound for detection local invasion in malignant causes
• Esophagogastroduodenoscopy (EGD) is done for staging suspicious malignant causes that were diagnosed in barium esophagogram
• Ct scan is used for staging malignant strictures
• Manometry is used in cases of esophageal stricture due to dysmotility
• Chest radiography can be used for diagnosis extrinsic compression as a cause of esophageal stricture
