Parasellar chondroma: a case report

Giant Chondroma of the Saddle Area: Case Report and Literature Review

A 63-year-old man presented with sexual dysfunction of 6-year duration, 5-year history of bilateral vision loss, and left nasal obstruction for 3 years. Brain computed tomography and magnetic resonance imaging showed a large mass lesion in the saddle area and extending upward to the dorsum sellae, bilateral cavernous sinus, and suprasellar region, and down into the sphenoid sinus and nasal cavity; the optic nerves and optic chiasm were elevated upward and compressed. Endocrine tests indicated that all serum level of anterior pituitary hormones decreased. The preoperative diagnosis included invasive pituitary adenoma, chordoma, osteosarcoma, chondrosarcoma, and craniopharyngioma. The tumour was subtotally removed through transsphenoidal approach. Histopathology examination revealed a chondroma. Postoperatively, the patient was stable and his visual acuity and visual field defect improved and his pituitary function return to normal except for hypothyroidism.

Chondroma of the petrous apex

The clinicopathological features of a chondroma of petrous apex area examined with magnetic resonance (MRI) are presented. The extreme rarity of the location, the MRI aspect, and the surgical strategy based upon MRI studies make this case noteworthy.

Giant chondroma arising from the dura mater of the convexity. Case report and review of the literature

Chondromas arising from the dura mater are rare intracranial tumors. The authors present a case of intracranial giant chondroma originating from the dura mater of the convexity. Neuroimaging and surgical findings are described. The diagnostic clues are discussed and similar cases from the literature are reviewed.

Chondroma of the cerebellopontine angle. Case report

A patient is reported who had a solitary chondroma of the cerebellopontine angle. The tumor was totally removed. The diagnostic value of CT-scanning and MRI in this rare pathological condition are discussed.

Giant chondroma of the falx. Case report and review of the literature

The authors describe the radiological and pathological features in a patient with an intracranial chondroma originating in the falx cerebri. Diagnostic procedures and management in treatment are discussed, and a review of the literature is presented.

Solitary intracranial chondroma of the convexity dura: case report

We present a rare case of chondroma originated from the dura mater of the cerebral convexity in a 16-year-old girl. Radiologic findings are reported with emphasis on computed tomography and magnetic resonance imaging scans, and histogenesis is briefly discussed.
