“…Since that time, and including our case, three more have been added (Gorman, 1960;Ramamurthi, Iyer, and Vedachalam, 1961;Geuna and Gori, 1962) ' Coley and Higinbotham (1949) emphasize the propensity of chondromas to undergo malignant change just as chondromas in large bones sometimes do and as happened in Alper's case. Other authors have noted that tumours of the convexity are larger than those of the base due to lack of early symptoms.…”

“…David and Constans found 22 pure chondromas of the convexity and added the 23rd in 1957. Since that time, and including our case, three more have been added (Gorman, 1960;Ramamurthi, Iyer, and Vedachalam, 1961;Geuna and Gori, 1962) for a total of 29. In the English literature, Chorobski intracranial cartilaginous tumours are summarized by Flyger et al (1963) as follows: 'They occur principally in males age 18 to 65, some originate in the base of the skull, but some are not connected with skull bones.…”

Primary intracranial cartilaginous neoplasms which do not arise from bones of the skull are extremely rare (Alpers, 1935;Chorobski, Jarzymski, and Ferens, 1939;Dahlin and Henderson, 1962;Flyger, Freidenfeldt, and Orell, 1963;Siris and Angrist, 1942). We report herein two such tumours; one benign and the other malignant.CASE 1: CHONDROMA During the seventh month of pregnancy L.W., a 32-yearold white woman, began to exp-rience fainting spells of 15 minutes' duration followed by increasingly severe speech difficulty and weakness in the right arm. She was admitted to the hospital approximately one month after delivery, or three months after the onset of symptoms, at which time she was having generalized convulsions, bit her tongue, and lost consciousness for a 30 minute period.The past history, family history, and system review were negative or non-contributory except as related to the present illness.Physical examination revealed a well-developed, wellnourished, white female with mild speech slurring. There was a contusion in the right frontal region of the scalp.The fundi showed slight blurring of the nasal and upper disc margins and the pupils were equal and reacted to light. Right hemiparesis with hyperactive reflexes on the right was present. Hoffman's sign was positive on the right, but the Babinski reaction was negative. There was no astereognosis.Moderate nasal obstruction with yellowish nasal discharge was noted. Artificial dentures were well-fitting and oral hygiene was good. The breasts were full and lactating. The physical examination was otherwise negative and the blood pressure was 130/70 mm Hg.Radiographs of the skull showed a shell-like calcification on the left just posterior to the coronal suture and in the region of the middle meningeal vessels, the grooves of which appeared more pronounced on the left. The adjacent skull was thickened, but the falx, although calcified, was not shifted. The sella was intact.A left carotid arteriogram showed an abnormal vascular pattern in the left parietal area adjacent to the skull. Ventriculography disclosed downward displacement of the lateral, superior portion of the left lateral ventricle.

“…1 Traumatic displacement is considered an alternative explanation of these clinical entities; in 2005, Hong et al 16 reported a case of intracranial chondroma at the site of a skull fracture that had occurred years earlier. According to Ramamurthi et al, 31 as well as Russell and Rubinstein, 34 aberrant nesting of cartilaginous tissue could also be an explanation for the development of these tumors. Chondromas are usually opalescent, firm, relatively large, and lobulated.…”

Intracranial osteolipomas and chondromas are rare benign tumors. Forty-five chondromas, mostly supratentorial, have been reported in the literature since 1981, with origins most commonly in the sellar regions. Twenty-one osteolipomas have been described to date, usually located near the tuber cinereum or the corpus callosum. The authors present a case of an osteochondrolipoma arising from the tentorium diagnosed in a pediatric patient at the age of 9 years. The case and treatment are discussed, and a review of the literature is provided.

“…22,23 T he paucity of cartilaginous rem nants in the dura (in contradistinction to the m arked occurrence of benign dural calci® cation and ossi® cation) 23 m akes this hypothesis unlikely. T he other possible cell of origin is the pluripotential m esenchymal cell, 24 which has the capacity to differentiate into cartilage as evidenced by cartilaginous inclusions in som e m eningiomas 25 and gliom as. 19 It is thus clear that tum ours arising intradurally at the convexities, best called`meningeal chondrom as' , should not be confused with skull base chondrom as: their pathogenesis is different and they present different clinical and therapeutic challenges.…”
