Role of Diagnostic Imaging in Chronic Recurrent Multifocal Osteomyelitis (CRMO) in Children: An Observational Study.

The aim of this single-center observational study was to analyze the applicability of various imaging studies to the diagnosis and further evaluation of patients with chronic recurrent multifocal osteomyelitis (CRMO). The analysis included the data of 10 patients with CRMO treated between 2016 and 2021. The mean ages of the patients at the first manifestation of CRMO and ultimate diagnosis were 10 years and 7 months and 11 years and 10 months, respectively.

Tumour of the orbit and pterygopalatine fossa: delayed recognition of possible IgG4-related disease.

Introduction: IgG4-related disease (IgG4-RD) is a systemic fibrotic-inflammatory disease characterised by elevated serum concentration of IgG4 and tissue infiltration by plasma cells. IgG4-RD is a newly recognised fibro-inflammatory condition, characterised by organ mass lesions, special histopathological appearance, and - often but not always - elevated serum IgG4 concentrations. IgG4-RD is a separate, clinically distinct disease entity, but, due to its heterogeneous manifestation, it is a subject of interest of physicians of various specialties.
