Chondroblastoma of the temporal bone is a rare condition. Chondroblastomas account for less than 1% of primary bone tumors, and those involving the temporal bone represent a tiny fraction of these tumors with most arising from the knee, rib, and pelvis. We present a case series of two patients who presented with chondroblastomas of the temporal bone over a period of 8 years to the St. Vincent's...

The first aim was to differentiate chronic infection from neoplastic bone lesions. Acid fast bacilli culture excluded a tuberculous infection. Confirmation was achieved by performing an open biopsy and histopathological examination of the specimen. The final diagnosis of chondroblastoma was confirmed in view of there being a marked cellular chondroid component rather than fibrous component in t...

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...
