Chondroblastoma of the temporal bone.
Chondroblastomas are highly destructive tumors that are derived from immature cartilage cells. The occurrence of this tumor in the temporal bone or skull base is uncommon. Approximately 70 cases have previously been reported, several of which have involved the temporomandibular joint (TMJ). We report here the case of a 67-year-old woman who presented with right-sided mixed hearing loss, a right...
متن کاملMR of benign chondroblastoma of the temporal bone.
A benign chondroblastoma of the temporal bone in an 8-year-old boy is reported. Head CT showed an expansile mass with calcifications in the center. The tumor appeared as a well-lobulated, hypointense intraosseous mass on T1-weighted brain MR; it was isointense to brain parenchyma on intermediate-weighted images and enhanced homogenously with gadolinium.
متن کاملChondroblastoma of the temporal bone: CT and MR appearance.
The authors report a case of chondroblastoma in the unusual location of the temporal bone. CT findings do not differ dramatically from other reports: the lesion appeared as a soft-tissue density mass in the right temporal bone, with bony destruction and thinning of cortical margins. MR findings are more rare: on coronal T1-weighted images the lesion appeared as a mass, isointense to gray matter...
متن کاملDual-time-point FDG-PET/CT Imaging of Temporal Bone Chondroblastoma: A Report of Two Cases
Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...
متن کاملChondroblastoma of the Navicular Bone
This is a case report of a 24-year-old man who presented with increased pain and firm swelling of the right foot after a minor twisting injury. Radiography, computed tomography (CT) and magnetic resonance imaging (MRI) findings showed ancillary information that was helpful for surgical treatment. The final diagnosis was confirmed as chondroblastoma of the navicular bone based on the pathology r...
