Which tumor has soap bubble appearance?
Giant cell tumours of bone tend to be lytic and expansile, being surrounded by a thin shell of bone, resulting in a ‘soap bubble’ appearance radiologically. They typically arise near the ends of long bones.
What pathology appears radiographically with a soap bubble appearance?
Odontogenic myxomas often have a distinctive radiographic presentation described as a “soap bubble”, “tennis racket”, or “honeycomb” pattern. Less frequently, examples of odontogenic myxomas with a “sunray” or “sunburst” pattern have been reported.
How rare is a giant cell Tumour?
Giant cell tumors usually occur in young adults, and are slightly more common in females. They are quite rare, occurring in only about one out of every one million people per year. Although giant cell tumors are not cancerous, they are aggressive and can destroy the surrounding bone.
Which tumor shows osteoclastic giant cells?
Giant-cell tumor of the bone (GCTOB), is a relatively uncommon tumor of the bone. It is characterized by the presence of multinucleated giant cells (osteoclast-like cells). Malignancy in giant-cell tumor is uncommon and occurs in about 2% of all cases.
Can giant cell tumors be malignant?
The term malignant giant cell tumor has been used in soft tissues to describe a tumor with a mixture of benign giant cells and malignant mononuclear cells. This has been considered to be a type of malignant fibrous histiocytoma and probably not related to true benign giant cell tumors of soft tissue.
What is the imaging modality that would best demonstrate osteomyelitis?
MRI is the best imaging modality for establishing the diagnosis of osteomyelitis as it can demonstrate bone marrow oedema, confirm the presence of abscesses and delineate extraosseous disease spread. If MRI is contraindicated or unavailable, nuclear medicine studies and CT are useful alternatives.
What imaging modality would demonstrate developmental dysplasia of the hip?
Ultrasonography (US) is a useful screening method for the diagnosis of developmental dysplasia of the hip (DDH) and congenital spinal anomalies in infants. In addition, US is a useful, noninvasive imaging modality for the diagnosis of transient synovitis in children.
What do giant cell tumors feel like?
The most common symptom of a giant cell tumor is pain in the area of the tumor. The patient may also have pain with movement of the nearby joint. This pain usually increases with activity and decreases with rest. The pain is usually mild at first, but gets worse over time as the tumor increases in size.
