Unilateral muscle hypertrophy and focal myositis following S1 radiculopathy.

Focal myositis following neurogenic damage should be differentiated from focal nodular myositis. Unlike nodular myositis which can occur in any muscle and clinically presents as nodular masslike tumefaction, post-sciatica focal myositis involves calf muscles and it presents as a muscle hypertrophy. The levels of muscle enzymes are high in post-sciatica focal myositis, while they are within the normal limits in focal nodular myositis. On MRI ‘nodular’ type of lesion and intense, homogeneous, contrast enhancement of the involved muscle is present in nodular focal myositis, while in postsciatica focal myositis diffuse muscle hypertrophy and moderate contrast enhancement is usually found.
