Osteitis condensans ilii is a noninflammatory condition of an uncertain etiology, characterized by sclerotic bone lesions located mainly in the iliac region of the sacroiliac joints. In many patients, osteitis condensans ilii remains an incidental imaging finding; however, it has been associated with lower back pain and may mimic inflammatory rheumatic conditions such as axial spondyloarthritis. ⋯ Herein, we conducted a narrative literature review using the terms osteitis condensans ilii, and we identified case reports, case series, reviews, and original studies associated with the condition. The aim of this article is to raise the awareness of this underrecognized clinicoradiological condition and to enable the health-care providers to recognize clinical and radiological features that should raise suspicion of the osteitis condensans illi, and to describe the treatment options.

Eosinophilic granulomatosis with polyangiitis presenting with myositis: case based review.
Eosinophilic granulomatosis with polyangitis (EGPA) is a systemic necrotizing small-vessel vasculitis that presents heterogeneously as a multi-organ disease. EGPA evolves through three phases: (1) prodromic phase with asthma, atopy and sinusitis, (2) eosinophilic phase characterized by peripheral eosinophilia and eosinophilic infiltration without necrosis, and (3) vasculitic phase involving organ damage. EGPA often presents with asthma, mononeuritis multiplex, lung infiltrates, sinusitis and constitutional symptoms. ⋯ Based on our literature review, there are only seven similar cases reported of EGPA presenting with myositis and confirmatory muscle biopsies. There is significant heterogeneity in their clinical findings, histopathology and treatments that were used. Our case report and literature review highlights the importance of recognizing myositis as an initial presenting symptom of EGPA, providing an opportunity for early diagnosis and treatment to reduce risk of further disease progression and morbidity.
