“…Relationships of transient osteoporosis, reflex symphatetic dystrophy and regional migratory osteoporosis remain controversial [7,32]. All these pathologic processes consist of altered signal intensity in the marrow of the femoral head and neck because of bone marrow edema [32] and represent the main differential diagnosis with intra-articular OO. After resection of OO nidus, a complete disappearance of bone marrow edema occurs within 4-10 weeks (unpublished data) (Fig.…”

Magnetic resonance imaging findings of osteoid osteoma of the proximal femur

Osteoid osteoma (OO) is a benign bone tumor whose main radiological finding is nidus. OO of the proximal femur can also result in non-specific findings such as hip joint effusion, perinidal bone marrow edema and soft tissue mass. Since the nidus may be difficult to identify with MR, these non-specific findings can lead to erroneous diagnosis. Therefore, MR imaging technique should be optimized in order to identify nidus. Since MR imaging has assumed increasing importance in the evaluation of disorders of the hip, radiologists must be aware of the spectrum of findings of OO of the proximal femur. The aim of this pictorial review is to show the MR imaging findings of intra-articular and extra-articular OO of the proximal femur.

“…Das KMÖ tritt an unterschiedlichen Lo kalisationen auf, am häufigsten jedoch am proximalen Femur, und wurde un ter vielen Synonymen beschrieben, so als transiente Osteoporose, Algodystrophie, sympathische Reflexdystrophie, transien tes KMÖ und als frühe Form der Osteo nekrose (ON; 14,33]). Viele, insbesonde re vaskuläre Faktoren werden ursächlich beschrieben, jedoch bleibt der exakte Pa thomechanismus weiterhin unklar [21,33].…”

The differentiation of at least 3 different etiologies is proposed (mechanic, reactive and ischemic). Difficult, but important, is the distinction between the mostly painful, but benign entities (BME syndrome, bone bruise) and the progressive pathologies (osteonecrosis, arthritis, CRPS, tumour). Treatment options are dependent on etiology and clinic and can often be symptomatic. Core decompression is the surgical gold standard, leading to immediate pressure relief and therefore reduction in pain. Recently, it was shown that intravenous administration of Iloprost and bisphosphonates are also effective in achieving a reduction of BME and pain, with considerable improvement in the accompanying symptoms. The combination of core decompression and infusion seems to be another possible optimization ofthe therapy, in particular in the treatment of osteonecrosis.
