Objective:
To analyze magnetic resonance imaging (MRI) of the elbow area to quantify the presence of the anconeus epitrochlearis muscle.
Methods:
A total of 232 exams were analyzed; 218 were included, of which 141 were of men and 77, women.
Results:
Presence of the muscle was observed in 29 cases (13.3%), demonstrating that the presence of this muscle on images does not have a statistical correlation with the gender or age of the individual.
Conclusion:
The prevalence of the anconeus epitrochlearis muscle is variable, without a pattern of normality.
