ABSTRACT
ABSTRACT Chronic recurrent multifocal osteomyelitis (CRMO) is a rare idiopathic inflammatory disease that affects mainly children and young adults. The clinical signs and symptoms are nonspecific, hindering and delaying diagnosis. Radiological and histopathological tests are essential for its definition. A case of CRMO is reported, demonstrating the importance of clinical, laboratory, and radiological data for diagnosis.,
RESUMO Osteomielite crônica multifocal recorrente (OCMR) é uma doença inflamatória idiopática rara que acomete principalmente crianças e adultos jovens. Os sintomas e sinais clínicos são inespecíficos, dificultam e retardam o diagnóstico. Os exames radiológicos e histopatológicos são indispensáveis para sua definição. Neste relato, os autores apresentam um caso de OCMR que demonstra a importância dos dados clínicos, laboratoriais e radiológicos para o diagnóstico.

The aim of this study was to report on a rare case of Garré's sclerosing osteomyelitis. The patient was a 54-year-old woman with a history of treatment for lupus using corticoids for 20 years, and for osteoporosis using alendronate for five years. She presented edema and developed a limitation of left knee movement one year earlier, with mild effusion and pain on metaphyseal palpation, but without fever. She was in a good general state, without local secretion. Images of her knee showed trabecular osteolysis of the distal metaphysis of the femur and a periosteal reaction in both proximal tibias and both distal femurs, compatible with chronic osteomyelitis of low virulence and slow progression. Magnetic resonance imaging showed T2 hypersignal in the femur and tibia. Curettage was performed on the left distal femur, with release of secretion, but this was negative on culturing. A biopsy showed chronic infection and inflammation, fibrosis, xanthogranulomatous reaction and foci of suppuration. Antibiotic therapy was administered for six months. The etiology was not clarified: bacterial infection was suspected, but culturing was generally negative. The chronic process was maintained by low-virulence infection or even after treatment. The differential diagnoses were fibrous dysplasia, syphilis, pustulosis palmoplantaris, rectocolitis, Crohn's disease, SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis) and Paget's disease. The unifocal diseases were osteoid osteoma, Ewing's disease, osteosarcoma and eosinophilic granuloma...
Relatar um caso raro de osteomielite esclerosante de Garrè. Paciente feminino, 54 anos, com história de tratamento de lúpus com corticoide havia 20 anos e osteoporose, em uso de alendronato havia cinco anos. Apresentava edema e limitação do joelho esquerdo havia um ano, derrame leve, dor à palpação metafisária, afebril, bom estado geral, sem secreção local. Imagens do joelho evidenciaram osteólise trabecular da metáfise distal do fêmur e reação periosteal nas duas tíbias proximais e nos dois fêmures distais, compatíveis com osteomielite crônica, de baixa virulência e progressão lenta. Hipersinal em T2 no fêmur e tíbia à ressonância. Curetagem do fêmur distal esquerdo, com saída de secreção, mas cultura negativa. Biópsia evidenciou infecção e inflamação crônica, fibrose, reação xantogranulomatosa e focos de supuração. Feita antibioticoterapia por seis meses. Etiologia não esclarecida, suspeita de infecção bacteriana, mas geralmente a cultura é negativa, processo crônico mantido por infecção de baixa virulência ou mesmo após o tratamento. Diagnósticos diferenciais: displasia fibrosa, sífilis, pustulose palmoplantar, retocolite, Crohn, Sapho (sinovite, acne, pustulose, hiperostose, osteíte) e Paget. Unifocais: osteoma osteoide, Ewing, osteossarcoma e granuloma eosinofílico...
