Convexity dural chondroma: a case report and review of the literature

Falx Cerebri Giant Chondroma ‒ Case Report

“…They develop due to heterotrophic chondrocytes, metaplasia of perivascular mezenchymal cells or meningeal fibroblasts or migration caused by trauma or inflammatory process [18,20,21]. Heterotypically located embryonal cartilaginous remanants are most likely the origin of falx chondromas [8]. Without a head trauma history, we can support the idea that the chondroma in our report had its origin in intradurally located embryonal cartilaginous rests in the falx cerebri.…”

“…The majority of patients are between 20 and 60 years of age with a high frequency around the third decade [1,8]. Although a slight female preference has been reported, there is no gender predominance [9].…”

“…Exceptionally rare, chondromas developed from the falx cerebri [12,13], with an estimated incidence of 5.6-6.3% of all intracranial chondromas [14]. Depending on various authors, between 14-15 cases were reported in the literature [1,8,[12][13][14][15][16]. In a very recent study, Zivkovic et al summarized 16 cases, including their, of falx cerebri chondroma [17].…”

A Soft Tissue Chondroma Originating from the Dura Mater of the Lumbar Spinal Canal and it Mimicked a Nerve Sheath Tumor: A Case Report with the MR Imaging

“…There are 127 reports of intracranial chondroma in the English-language literature (3,4,8). Among them, 19 cases were reported as having originated from the falx and dural convexities (3).…”

“…In particular, the mass showed a peripheral enhancement that extended along the neural foramen, and this mimicked a nerve sheath tumor. Some published papers have confusingly used the terms "chondroma of a dural origin" (3), "intracranial chondroma" (4) and "dural chondroma" (8), and they failed to distinguish whether the tumor was categorized as a soft tissue tumor or a bony tumor. The distinctions were based on the pathological findings.…”
