Summary
This case highlights an unusual intracranial chondrosarcoma with intratumoural hemorrhage. Careful imaging analysis is crucial for surgical decision-making in rare brain tumors.
Area of Science:
- Neuro-oncology
- Surgical Pathology
- Diagnostic Imaging
Background:
- Intracranial chondrosarcomas are rare malignant tumors producing cartilage.
- They typically arise at the skull base as extra-axial masses.
Observation:
- A 46-year-old man presented with symptoms of increased intracranial pressure.
- Imaging revealed a large, heterogeneous, partially calcified frontal mass with midline shift.
- Intraoperative findings initially suggested subdural hematoma.
Findings:
- Pathology confirmed a high-grade (Grade III) conventional chondrosarcoma.
- The tumor presented with intratumoural hemorrhage in an unusual location.
- Unusual presentations can complicate pre-surgical diagnosis.
Implications:
- This case underscores the importance of integrating imaging findings into surgical planning.
- Recognizing specific imaging characteristics suggestive of chondrosarcoma is vital.
- An aggressive surgical approach may optimize adjuvant therapies for these rare tumors.

Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
