Chondroblastoma of the temporal bone

Abstract

CONCLUSIONS: Temporal bone chondroblastomas are extremely rare and aggressive, but the outcome after appropriate surgical treatment is favorable. From the review, it may be particularly important to deal with tumors that involve the temporomandibular joint (TMJ), which could affect the long term outcomes, as well as tumor recurrence.OBJECTIVE: To report a case of chondroblastoma and to review their presentation.BACKGROUND: Chondroblastomas are highly destructive tumors that are derived

Incidental Discovery of a Temporal Bone Chondroblastoma on an Archived Histopathologic Section

“…According to others (5), embryonal cartilaginous rests entrapped within the tympanosquamous suture line of the temporal bone could be the origin from which chondroblastoma arise; however, our case does not corroborate this hypothesis. One theory we propose based on the particular location we report here is a possible relationship between chondroblastoma and the globulae interossei observed in temporal bones.…”

Chondroblastoma of the Clivus: Case Report and Review

“…10,40,44 The clival lesion we present appeared intermediate intensity on T1-weighted and low intensity on T2-weighted sequences, consistent with endochondral bone formation and cartilaginous tumor matrix rather than chronic blood products.…”

Temporal bone chondroblastoma: Imaging characteristics with pathologic correlation

“…Imaging features of 11 patients with temporal bone chondroblastoma from the literature series are summarized in Table . They presented a common location (ie, the squamous portion [9/11] rather than the petrous portion [2/11]).…”

“…In addition, for the complementary analysis of imaging features, a PubMed search was performed for English‐language literature on temporal bone chondroblastoma from 1980 to 2016, by using the keywords “temporal” and “chondroblastoma.” Of 68 articles, 11 cases of temporal bone chondroblastoma from 10 articles that presented MRIs with complete sequences of T2‐weighted imaging and T1‐weighted imaging were chosen . The patients of the literature series included 7 men and 4 women, with an age range of 8‐64 years (mean age 39.0 years).…”
