The onset of the disease is insidious, occurring in males before the age of 30 years, with a clinical course marked by non-progression.

In imaging Hyperintense T2w MRI longitudinal lesion in ventrolateral segment of cord in C4-C5- C6.According to history and physical exam and after rule out of its DDx, benign focal amyotrophy is the best diagnosis for the patient.
