Clinical Presentation
A 14-year-old boy presented with neck pain after a football accident, highlighting that BFH can manifest with subtle symptoms post-traumatic events [PMID:26991583].
This report describes a 28-year-old patient with a giant benign fibrous histiocytoma located in the popliteal fossa of the right knee, highlighting the potential for significant size and deep tissue involvement [PMID:9683707].
Diagnosis
Imaging revealed a characteristic mass extending anterior from the C2 vertebral body, underscoring the importance of recognizing such features in diagnosing BFH [PMID:26991583].
Magnetic resonance imaging revealed a well-delineated oval mass with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, along with marked peripheral contrast enhancement, in a case of giant deep benign fibrous histiocytoma [PMID:9683707].
The mass demonstrated marked peripheral contrast enhancement on imaging, which is a notable feature aiding in the diagnostic differentiation of benign fibrous histiocytoma [PMID:9683707].
Differential Diagnosis
The differential diagnosis for spinal masses includes a wide range of entities, emphasizing the necessity of thorough evaluation including tissue sampling to distinguish BFH [PMID:26991583].
