“…Due to the slow growth of chondromas, no peritumoral edema appears on MRI. It has also been reported that the cartilage matrix in chondroma can lead to its low signal on diffusion-weighted imaging (DWI), and the arrangement of cells in the lesion shows the apparent diffusion coefficient ( 19 , 20 ). The imaging characteristics, including the “snowman” shape of pituitary tumor, “dural tail sign” of meningioma, vascular lumen and thrombus of cavernous hemangioma, and eggshell calcification of craniopharyngioma, could distinguish ICDs from other tumors ( 21 – 23 ).…”

ObjectiveTo improve the diagnosis and treatment of intracranial chondromas (ICDs) by discussing the clinical manifestations and imaging characteristics of ICDs, as well as surgical methods and treatment strategies.MethodsWe retrospectively analyzed 17 patients diagnosed with ICDs who underwent microsurgery or endoscopic transsphenoidal surgery at the Tangdu Hospital of Air Force Military Medical University and the Mianyang Central Hospital from January 2010 to November 2021. Clinical manifestations, imaging examinations, surgical treatments, and prognosis of these patients were analyzed.ResultsICDs had often been misdiagnosed as craniopharyngioma, chordoma, schwannoma, cavernous hemangioma, pituitary adenoma, and meningioma before surgery. Of the 17 cases, gross total resection (GTR) was performed in 10 cases, subtotal resection (STR) in 5, and partial resection in 2. GTR of tumor was achieved in eight cases via the endoscopic endonasal transsphenoidal approach (EETA) or the extended endoscopic endonasal transsphenoidal approach (EEETA), and the remaining patients underwent craniotomies. Clinical symptoms were assessed 1 week after surgery, 10 cases were relieved at varying degrees, and four cases had no improvement. Postoperative complications included right-limb hemiparesis, diplopia, eyelid ptosis, pulmonary infection, subcutaneous hydrops, cerebrospinal-fluid leakage (CSFL), and intracranial infection (ICI). One patient received gamma knife treatment at 3 months after surgery, two patients died due to tumor progression, and the remaining patients had no tumor recurrence.ConclusionsICDs lack typical imaging features and are often misdiagnosed. The EETA or EEETA helps improve the surgical outcomes and GTR rates of ICDs at different sites.

“…9 Chondromas, however, are typically DWI hypointense and ADC bright. 10 Moreover, chondromas are avascular on cerebral angiograms compared with classically hypervascular meningiomas. 11 Nevertheless, calcified meningiomas or other osseous tumors (i.e.…”

Intracranial dural chondroma in a child—conventional and advanced neuroimaging characteristics and differential diagnosis

Intracranial chondromas are rare tumors, especially in the pediatric population. We describe the conventional and advanced neuroimaging characteristics of this rare convexity dura-based chondroma in a young adolescent. In particular we demonstrate that diffusion-weighted imaging (DWI) facilitates differentiation between a dura-based chondroma and the more frequent classical meningioma. Chondromas are typically DWI hypointense with high apparent diffusion coefficient (ADC) values while meningiomas are typically DWI hyperintense with low ADC values. We also discuss the relevant additional differential diagnoses of dura based focal lesions for the pediatric population as well as the diagnostic significance of additional imaging modalities, including computed tomography, magnetic resonance imaging and cerebral angiography.
