What is an expansile bone lesion?
This is most often seen with osteochondnoma, chordoma, myeloma and aneurysmal bone cyst. An expansile vertebral lesion may be osteolytic, osteoblastic, or mixed (Table I). The margin of a benign lytic lesion iswell defined and sclerotic, whereas an aggressive, malignant lesion shows ill-defined borders.
What benign conditions cause lytic lesions?
[5] The most common benign bone lesions are osteochondroma, enchondroma, and simple bone cysts. Benign bone tumors are more prevalent than malignant bone tumors in the younger age group.
Can multiple myeloma cause skull lesions?
The classic radiographic appearance of multiple myeloma is that of multiple, small, well-circumscribed, lytic, punched-out, round lesions within the skull, spine, and pelvis. The pattern of lytic or punched-out radiolucent lesions on the skull have been described as resembling raindrops hitting a surface and splashing.
What is lytic expansile lesion?
Expansile lytic bone lesions without cortical destruction can result from various benign and malignant neoplastic pathologies, causes include 1: unicameral bone cyst. aneurysmal bone cyst (eccentric) enchondroma.
Do lytic lesions cause pain?
Lytic lesions are areas where bone has been destroyed, leaving a hole in the bone. These lesions in the spine are common, and when severe, can lead to one or more vertebral compression fractures, which can be painful and even disabling.
Are lytic lesions cancerous?
What are Lytic Lesions? Also known as bone lesions or osteolytic lesions, lytic lesions are spots of bone damage that result from cancerous plasma cells building up in your bone marrow. Your bones can’t break down and regrow (your doctor may call this remodel) as they should.
Do bone lesions cause pain?

- mass effect on adjacent structures. compression of brain/brainstem. focal neurological deficits. seizures.
- mechanical instability. occipital condyle compression fracture. temporomandibular joint instability.
