What is a Chondroid Matrix?

Abstract. Chondroid tumors are a heterogeneous group of neoplasms that all share the production of chondroid matrix. This ranges from a fetal type to mature hyaline cartilage and mirrors its imaging characteristics.

What is a Chondroid series lesion?

Chondroid lesions are extremely common incidental findings on musculoskeletal MRI studies, since the femur and humerus are the most common location for chondroid tumors of the appendicular skeleton. Malignant degeneration of a solitary benign enchondroma is rare, but has been reported.

What is Chondroid?

adjective. cartilaginous or resembling cartilage.

What is Chondroid calcification?

Rings and arcs calcification is characteristic of chondroid lesions, such as enchondromas and chondrosarcomas. It is due to endochondral mineralization of multiple hyaline cartilage nodules and is similar to popcorn calcification, which has rings and arcs on the background of more amorphous calcification.

Is Chondroma the same as enchondroma?

Synonym. Chondroma is a lesion of mature hyaline cartilage that may be located centrally within the bone (enchondroma) or may arise either in or beneath the periosteum (periosteal or cortical chondroma, respectively).

Does enchondroma require surgery?

In the majority of cases, enchondromas do not require treatment. In rare cases, however, multiple tumors may weaken the bone, causing it to fracture. When this occurs, surgery may be needed to remove the tumor and prevent additional fractures.

What causes Ollier’s disease?

In most people with Ollier disease, the disorder is caused by mutations in the IDH1 or IDH2 gene. These genes provide instructions for making enzymes called isocitrate dehydrogenase 1 and isocitrate dehydrogenase 2, respectively.

What causes endosteal scalloping?

Endosteal scalloping refers to the focal resorption of the inner layer of the cortex (i.e. the endosteum) of bones, most typically long bones, due to slow-growing medullary lesions. It is important to note that although it is evidence of a slow non-infiltrative lesion, it does not equate to benign etiology.

Can you tell if a tumor is benign with an MRI?

Benign tumors can grow but do not spread. There is no way to tell from symptoms alone if a tumor is benign or malignant. Often an MRI scan can reveal the tumor type, but in many cases, a biopsy is required. If you are diagnosed with a benign brain tumor, you’re not alone.

What percentage of bone lesions are cancerous?

Bone cancer is rare, making up less than 1 percent of all cancers. In fact, noncancerous bone tumors are much more common than cancerous ones. The term “bone cancer” doesn’t include cancers that begin elsewhere in the body and spread (metastasize) to the bone.

What is a Chondroid Lipoma?

Abstract. Chondroid lipoma is a rare, benign soft tissue tumor with features of both embryonal fat and embryonal cartilage that most often arises in the proximal limb and limb girdles of adult women.

Can benign bone lesions cause pain?

Benign tumors may be painless, but often they cause bone pain. The pain can be severe. Pain may occur when at rest or at night and tends to progressively worsen.

What is the chondroid matrix like in an enchondroma?

The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation.

What is the role of MRI in the workup of chondroid cancer?

MRI is not only a sensitive detector of chondroid lesions, but can be helpful in discriminating between benign and malignant lesions. It can also be used to guide the location of biopsies for the most accurate sampling.

How is chondroid matrix differentiated from bone infarct on X-ray?

Although chondroid matrix is highly recognizable, it can sometimes be difficult to distinguish from bone infarcts, especially on x-ray, since both have well-defined irregular margins with areas of fluid signal intensity and apparent calcification or ossification.
