the oesophagus: beyond cancer. Leiomyoma. Esophagram in AP projection demonstrates a smooth, lobulated filling defect within the mid-thoracic oesophagus at the level of the carina. Notice the filling defect makes an acute angle to the oesophageal wall, suggesting that this lesion is intrinsic to the oesophagus

Esophageal leiomyoma is a benign smooth muscle neoplasm of the esophagus. It is the most common benign tumor of the esophagus.
Epidemiology
It is most frequently presents in young and middle age groups (20-50 years). The overall incidence is around 8-43 per 10,000 autopsy series .
Clinical presentation
The clinical presentation would often depend on the size of a tumor:
- small tumors (<5 cm): usually no symptoms
- large tumors: may cause dysphagia, regurgitation, esophageal obstruction, chest pain, cough, or bleeding (rare)
Pathology
Like other leiomyomas, they comprise of smooth muscle overgrowth.
Location
They typically involve the mid-to-distal esophagus.
Radiographic features
Fluoroscopy
On barium swallow, may be seen as a discrete ovoid mass that is well outlined by barium. Its borders form slightly obtuse angles with the esophageal wall.
CT
Findings include:
- ovoid intramural solitary mass with a smooth surface
- the presence of calcifications is almost pathognomonic
- narrowing of the esophageal lumen
- may displace the esophagus
- moderate diffuse contrast-enhancement
- no signs of invasion of adjacent tissue
Treatment and prognosis
The overall prognosis of these benign tumors is excellent. If a tumor is small (<5 cm) and asymptomatic treatment is not necessary. Otherwise, surgical enucleation is recommended .
Differential diagnosis
Imaging differential considerations include:
- esophageal GIST
- esophageal carcinoma
- esophageal leiomyosarcoma
- esophageal hamartoma
- other mediastinal tumors arising close to the esophagus
- foreign body
