Iselin disease

Iselin disease is a benign and self-limiting condition, defined as apophysitis of the base of the 5 metatarsal.

Epidemiology

It is most commonly seen in males with sport injuries and is often also seen in adolescents.

Pathology

It is due to repetitive traction of the peroneus brevis tendon at the site of its attachment. Predisposing factors are jumping and running.

Radiographic features

Plain radiograph
  • obliquely oriented small bony fleck at the base of the 5th metatarsal which is best seen on oblique radiograph
  • apophyseal irregularity
MRI

Usually not considered essential for the diagnosis. But if performed may show:

  • T2/STIR: high signal intensity around base of 5metatarsal due to bone marrow edema
