Iselin disease ~~(ID)~~ is a benign and self-limiting condition, defined as apophysitis of the base of the ~~5th~~5^th 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 5^thmetatarsal due to bone marrow oedema ⁶

History and etymology

First described by H Iselin, a German physician in 1912 ⁴.

Differential diagnosis

On imaging consider:

normal apophysis
accessory ossicle (e.g. os vesalianum or os peroneum)
stress fracture
Jones fracture
