Abstract:
We report a case of large temporal giant cell reparative granuloma in a 72-year-old man. MR imaging depicted a right temporal expansile multiloculated lesion, with hyper- and hypointense signal areas on T2-weighted images, heterogeneously enhancing after gadolinium administration. Cortical thinning and bone remodeling of the temporal squamous portion were better seen on CT. The patient underwent surgery, and the diagnosis was achieved by the correlation of imaging, histologic, and laboratory findings.
Insights
We describe a large temporal giant cell reparative granuloma in an elderly male. Imaging revealed an expansile lesion, confirmed via surgery and histology, highlighting diagnostic correlations.
Area of Science:
- Neurology
- Radiology
- Pathology
Background:
- Giant cell reparative granulomas (GCRGs) are rare, benign bone lesions.
- These lesions can occur in various skeletal locations, including the temporal bone.
Observation:
- A 72-year-old man presented with a large, right temporal expansile, multiloculated lesion.
- MR imaging showed T2 hyper- and hypointense areas with heterogeneous enhancement.
- CT revealed cortical thinning and bone remodeling of the temporal squamous bone.
Findings:
- Surgical resection and subsequent histopathological examination confirmed the diagnosis of GCRG.
- Correlation of imaging, surgical, and laboratory findings was crucial for accurate diagnosis.
Implications:
- This case highlights the importance of integrating multimodal diagnostic approaches for temporal bone lesions.
- Understanding the imaging characteristics of GCRG is essential for appropriate clinical management.
- Early and accurate diagnosis can prevent unnecessary interventions and guide treatment strategies.
