Solitary intracerebral chondroma without meningeal attachment: a case report with review of the literature

When Chondroma Happens in an Unexpected Location: A Case Report of Intra-Axial Intracranial Chondroma

Chondroma is a benign tumor of mature hyaline cartilage that is often found in the long bones and may be rarely diagnosed in other parts of the body. Here, we present a young patient with the definitive diagnosis of intra-axial intracranial chondroma and without dural connection. The presenting symptoms of the patient were headache and impaired vision. The brain magnetic resonance imaging (MRI) revealed a huge enhancing parasagittal brain mass. The diagnosis was confirmed by immunohistochemistry, which was positive for S100.

An Intracerebral Type of Cranial Chondroma

The vast majority of intracranial chondromas are located in the base of the cranium. Their presentation as an intracerebral neoplasm is considered to be extremely rare. A previously healthy 45-year-old man experienced recurrent seizure attacks over a period of 6 months. Imaging studies of the brain revealed an ovoid and calcified mass which involve the cortex in the left frontal lobe. Intraoperatively, the mass had no adhesion to the dura and arachnoid membrane. The tumor was completely removed and the final diagnosis was intracerebral chondroma. The patient remained free of disease over the period of 18-years follow-up. This communication adds an unusual case to the literature on the chondroma that expressed in the form of an intra-axial space-occupying lesion in the frontal lobe.

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

Patient: Male, 44

Final Diagnosis: Falx cerberi chondroma

Symptoms: Headache

Medication: —

Clinical Procedure: Resection of the tumor

Specialty: Neurosurgery

Intracranial dural based chondroma

Intracranial chondromas are benign, slow-growing, cartilaginous tumors, which comprise only about 0.2% of all intracranial tumors. The majority of these lesions occur at the base of the skull, where they are thought to arise from residual embryonic chondrogenic cells along the basal synchondrosis. Very rarely, they may also originate from the convexity dura, falx cerebri, or the brain parenchyma. We present a patient with a dural based chondroma to highlight the technical considerations of surgical resection. The recent literature on intracranial chondromas regarding incidence, pathophysiologic origin, clinical symptoms, imaging, histopathology and prognosis is reviewed.

Intracranial cystic chondroma: a case report

INTRODUCTION

Intracranial chondromas are rare benign tumors with an incidence of 0.2% to 0.3% of all intracranial tumors. This is the first case of an intracranial chondroma reported from Pakistan.

CASE PRESENTATION

We report a case of a 23-year-old Asian man presenting with intracerebral chondroma of the left frontal lobe, which was eroding the dura matter. The intracranial chondroma was completely removed by surgery.

CONCLUSION

Intracranial chondromas are rare benign cartilaginous tumors. Through this case presentation we have discussed the diagnostic procedures, radiological and pathological findings. The purpose of presenting such a rare case is to develop awareness among clinicians and medical students and to highlight the requirement of immediate actions to ensure proper management of such cases.
