Granuloma annulare is a benign idiopathic inflammatory disorder of the dermis, characterised by formation of dermal papules in young children.
Clinical presentation
Granuloma annulare most commonly seen in kids between 2-12 years old and usually it occurs in exterminatesextremities. One typical location is pretibial when the lesion is subcutaneous. It has various clinical presentations:
- three cutaneous forms
- erythematous
- perforating
- generalised
- one subcutaneous form: presenting as a soft tissue mass - subcutaneous granuloma annulare
Radiographic features
Plain radiograph
These have very little value. The only manifestation is non-specific increased density in the subcutaneous compartment without involvement of bone involvement or mineralisation.
Ultrasound
Shows ill-defined solid mass that is hypoechoic to surrounding fat. It excludes a vascular of cystic lesion.
MRI
- T1: ill-defined subcutaneous mass, isointense to muscle
- T2: slightly hypointense signal intensity compared with fat, but may also show heterogeneous hyperintense signal
- T1 C+: diffuse enhancement can be seen
