“…Theories include origination from embryonic rests of synchondrosis cartilage cells, metaplastic meningeal fibroblasts and perivascular mesenchymal tissue, and ectopic embryological rests or displacement of cartilaginous elements secondary to trauma or inflammation. [4][5][6][7][11][12][13][14][15][16] It can also be associated with systemic cartilage tissue diseases including Ollier disease and Maffucci syndrome. 17,18 Clinical Presentation Headaches are the most common presenting symptom of intracranial chondromas, followed by seizures or focal neurological deficits.…”

BACKGROUNDChondromas are benign cartilaginous tumors that are rarely seen in the brain.OBSERVATIONSA 58-year-old woman had undergone routine brain imaging after a motor vehicle accident and was incidentally found to have a right falcine lesion. Contrast magnetic resonance imaging showed a mostly nonenhancing mass with discontinuous rim enhancement. She was taken to the operating room and pathology revealed a chondroma.LESSONSFalcine intracranial chondromas are rare and typically misdiagnosed as meningiomas. Chondromas should be in the differential for patients presenting with nonenhancing falcine lesions.

“…Intracranial chondroma can occur sporadically or may be associated with systemic enchondromatosis, such as Ollier's disease [9] and Maffucci's syndrome [10]. However, chondroma of the falx cerebri is rare, with only about 19 cases previously reported in the literature [1,3,7,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27].…”

Chondroma of the Falx Cerebri with Central Cystic Degeneration and Hemorrhage: A Case Report

Challenging differential diagnosis Background: Intracranial chondroma is a rare benign tumor that more commonly arises from the skull base. Chondroma arising from the falx cerebri is very rare, with only 19 cases previously reported in the literature. The imaging characteristics of intracranial chondroma and meningioma can be similar. Surgical excision and histology are required for the diagnosis. This report is of a case of intracranial chondroma that includes the imaging findings. The methods of diagnosis, management, and prognosis are discussed. Case Report: A 44-year-old man presented with episodes of severe headache. Magnetic resonance imaging (MRI) showed a well-defined, extra-axial, parafalcine lesion in the right frontal region. An interhemispheric craniotomy was performed. A right frontal solid and calcified tumor attached to the falx cerebri was identified and removed. Histology confirmed the diagnosis of a benign chondroma containing areas of hemorrhage and cystic degeneration. Conclusions: Chondroma arising in the falx cerebri is a rare intracranial tumor that may mimic meningiomas on imaging. Awareness of the varied imaging characteristics of these benign tumors is essential for planning the most appropriate treatment.

Chondroma is a benign cartilage-forming tumor which usually occurs in small bones of extremities but occasionally occurs in the brain. Usually, intracranial chondromas originate from skull base; however, chondroma of the falx cerebri is a very rare condition. We here report a rare case of falcine chondroma in a 19-year-old man who had normal physical examination without signs of any syndromic disorder. The neuroimaging findings were inconclusive, and the diagnosis was based on histopathological examination. The purpose of this paper is to raise attention about intracranial chondromas and suggest that chondroma must be ruled out in any patient presenting with masses arising from the falx.
