Giant cell arteritis (GCA), seen mainly in elders and rarely in children, has a female predominance. The present study discusses a case of biopsy-proven GCA with associated bilateral lower extremity myositis diagnosed on MRI and normal muscle enzymes. There are case studies on the occurrence of polymyalgia rheumatica (PMR) in GCA, but the involvement of lower limbs has not been reported. This report reiterates the importance of high clinical suspicion in the setting of occult and atypical presentations to avoid diagnostic delays.
