Critical role of STIR MRI in early detection of post-streptococcal periostitis with dysproteinaemia (Goldbloom's syndrome).

Objectives: In 1966, Goldbloom et al. described two children who developed a peculiar clinical picture characterized by intermittent daily bone pain in the lower limbs, fever spikes, increased acute phase reactants and dysproteinaemia. The syndrome occurred two weeks after a group A β-haemolytic streptococcus infection. So far, only a few cases have been reported in the medical literature in English.

Methods: We report two further cases of Goldbloom's syndrome with a review of the literature in English.

Results: Our two patients lived in the same Italian region and presented their syndrome onset a week apart. Early use of STIR MRI revealed an atypical metaphyseal hyperintensity in the femurs and tibias. X-ray showed periosteal hyperostosis. A short cycle of corticosteroids led to rapid recovery of symptoms and disappearance of bone changes.

Conclusions: The reported cases highlight a likely under-recognised post-streptococcal inflammatory periosteal reaction and emphasise the diagnostic utility of the newer imaging modalities.
