A CT scan is a valuable investigation in confirming the diagnosis. CT scan will show a mass of uniform density arising in the esophageal wall. Currently, endoscopic ultrasonography (EUS) has become a critical investigation for diagnosis of esophageal leiomyoma.
What is leiomyoma Oesophagus?
Leiomyomas are benign tumors descending from smooth muscle cells of the esophagus. They are the most common benign tumors of the esophagus and they may occur in all parts of the esophagus, but 60% occur in the distal third, 30% in the middle, and 10% in the proximal esophagus (4).
How often are esophageal tumors benign?
Benign esophageal tumors are rare, with a prevalence ≤ 0.5%[1], while benign tumors represent 20% of esophageal neoplasms on autopsy[2]. Since many of these tumors are small and asymptomatic, few benign esophageal lesions attract clinical attention.
How common are Leiomyomas?
Leiomyoma is the most common gynecological tumor. They affect 30–50% of the female population in reproductive age, and are predominantly found among individuals of African descent.
Is a leiomyoma a tumor?
Leiomyoma describes a benign growth of smooth muscle tissue. These tumors can occur anywhere in the body where smooth muscle is found such as the skin, the eyes, the uterus (commonly called fibroids), the bladder, and the gastrointestinal and respiratory tracts.
Are Leiomyomas Tumours?
Leiomyomas are benign tumors arising from smooth muscle, most commonly seen in uterine myometrium, gastrointestinal tract, skin and lower extremities of middle-aged women.
Is leiomyoma a real tumor?
What does esophageal leiomyoma look like on chest radiographs?
In summary, esophageal leiomyoma, usually located in the middle or distal esophagus, appears on chest radiographs as a posterior mediastinal mass. Esophagography, in which the tumor is seen as an intramural, eccentric, smoothly elevated, sessile lesion, varying in size, is the most reliable form of diagnosis.
What is oesophageal leiomyoma?
Oesophageal leiomyoma is a benign smooth muscle neoplasm of the oesophagus. It is the most common benign tumour of the oesophagus.
Can MR imaging improve the appearance of leiomyomas?
Understanding the MR imaging appearance of leiomyomas allows differentiation from other entities. The superior tissue contrast of MR imaging allows diagnosis of leiomyomas with a high level of confidence, ultimately leading to a decrease in the number of surgeries performed and thus reducing healthcare expenditures.
What does a leiomyoma look like on barium swallow?
Like other leiomyomas, they comprise smooth muscle overgrowth. They typically involve the mid-to-distal esophagus 4. 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.
