Aneurysmal bone cysts of the occipital bone
Surgical Neurology
|September 1, 1983
Summary
Aneurysmal bone cysts in the occipital region can cause posterior fossa compression. One unique case involved a cyst associated with an epidural hematoma, highlighting rare presentations of this bone lesion.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Pathology
Background:
- Aneurysmal bone cysts (ABCs) are benign, expansile, osteolytic bone lesions.
- Occipital bone involvement is rare, often presenting with neurological symptoms due to mass effect.
Observation:
- Two patients presented with occipital masses and posterior fossa compression symptoms.
- One case uniquely demonstrated an aneurysmal bone cyst co-occurring with an epidural hematoma.
Findings:
- Surgical excision was performed for both aneurysmal bone cysts.
- Histopathological examination confirmed the diagnosis of aneurysmal bone cysts.
Implications:
- Highlights the importance of considering aneurysmal bone cysts in the differential diagnosis of occipital masses.
- The association with epidural hematoma in one case suggests potential complex vascular or traumatic etiologies.
