OBJECTIVE
Chondrosarcomas rarely occur intracranially away from the skull base. We present a case of a supratentorial dural-based, low-grade classic chondrosarcoma and emphasize salient imaging findings that assist in its diagnosis.
METHODS
A 23-year-old female presented with new onset seizures.
BACKGROUND
We describe a patient with an intracranial extra skeletal myxoid chondrosarcoma (EMC), an unusual neoplasm of the deep soft tissues of the extremities. Very rarely are they localised as an intracranial lesion, and we believe it is very important to accurately distinguish EMC from other
A 60-year-old male was first treated for World Health Organization (WHO) grade II chondrosarcoma arising from the ring finger manifesting as painful swelling. Four years later, the patient presented with cerebral infarction. Echocardiography revealed a tumor occupying the left atrium. He underwent
BACKGROUND
Intracranial chondroid tumors are infrequently seen in neurosurgical practice. These tumors usually arise from cartilaginous synchondroses at the base of the skull, but occasionally from the pluripotential mesenchymal cells of the meninges. We present here a case of classic low-grade
BACKGROUND
Intracranial chondrosarcomas comprise 6% of all skull base neoplasms and account for 0.15% of all intracranial tumors. They are potentially fatal, invading the brain and elevating intracranial pressure by progressive enlargement. Diplopia and headache are the most common clinical
A 6-year-old, 35-kg, female spayed German wirehaired pointer was referred for evaluation of collapse/seizure-like activity and a suspected mediastinal mass. Echocardiographic examination revealed an obstructive, intraluminal aortic mass with aortic dissection. Gross and histopathological findings
Intracranial chondrosarcomas are cartilaginous tumours that are extremely rare with an estimated incidence of less than 0.16% of all intracranial neoplasms. They arise from the skull base synchondrosis or exceptionally from cartilaginous rests within the dura mater. This kind of tumours presents
Maffucci syndrome (MS) and Ollier disease (OD) are rare diseases characterized by multiple benign enchondromas. The incidence of skull base (SB) enchondromas and the risk of malignant transformation remain unknown. Most SB lesions are asymptomatic, and surgical resection carries A chondrosarcoma arising from the falx cerebri in a 15-year-old boy is reported. The patient had been suffering from convulsive seizures and weakness of the limbs on the left side for about 7 months prior to admission. A high-density mass attached to the falx was demonstrated by computed tomographic
BACKGROUND
Dural cavernous angiomas are uncommon benign vascular malformations which may present intraoperative difficulties in hemostasis when the diagnosis is not suspected preoperatively. Preoperative diagnosis can be difficult when angiomas show atypical features and share imaging
The authors experienced a case of histiocytosis X with a large intracranial mass resulting in a convulsive seizure. The patient showed left exophthalmos and a skin rash one year and two months after birth. Histiocytosis X was diagnosed from a skin biopsy, and predonine, endoxan and vincristine were
Neurologic abnormalities were the predominant historic and physical findings in 5 dogs and 2 cats with primary nasal cavity tumors that had invaded the cranial vault. Seizures, behavior changes, and obtundation were the most common signs. Other neurologic signs included paresis, ataxia, circling,
OBJECTIVE
Despite increased utilization of fractionated stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS), the incidence and nature of immediate side effects (ISE) associated with these treatment techniques are not well defined. We report immediate side effects from a series of
A patient with seizures and a contrast-enhancing temporal lesion after radiation therapy for a chondrosarcoma of the nasal septum is described. To differentiate between radiation necrosis and recurrent tumor, thallium-201 (201Tl) SPECT was used. 201Tl SPECT revealed high local accumulation
At present, only a little is known about the transcriptional regulation in chondrocytes submitted to various physicomechanical factors known to exist in articular cartilage. Recently, we have investigated the effects of hydrostatic pressure on transcriptional control in chondrocytes using human
