Objective To analyze the magnetic resonance imaging (MRI) features of Brucella coxarthritis. Methods This study retrospectively enrolled 83 patients with Brucella coxarthritis admitted to The Sixth People""s Hospital of Zhengzhou from January 2016 to December 2023 as research subjects. All patients underwent magnetic resonance imaging (MRI) examinations. We analyzed the serological test results of Brucella coxarthritis and the involved sides of the hip joint as shown by MRI, and meanwhile analyzed the imaging manifestations of typical cases with different pathological types. Results Among the 83 patients with Brucella coxarthritis, 70 were male and 13 were female; 50 cases had unilateral lesions (19 on the left side and 31 on the right side), and 33 cases had bilateral lesions. In the acute phase, MRI showed hyperintensity on T2-weighted imaging (T2WI) and T2WI fat suppression sequences. In the chronic phase, articular cartilage destruction and hypointensity were observed, and some patients had fat deposition in the lesion area. Among the 33 patients with bilateral lesions, 25 had basically consistent MRI findings in both hip joints, while 8 had inconsistent manifestations in the hip joints. Conclusion For patients with Brucella coxarthritis, MRI can provide detailed imaging information, assisting clinicians in making an accurate diagnosis and formulating a rational treatment plan.
