Giant cell tumour of bone Radiology Reference Article

  1. Giant cell tumours are low-grade tumours even in radiologically aggressive appearing lesions. Approximately 5-10% are malignant 1. Sarcomatous transformation is seen, especially in radiotherapy treated inoperable tumours. Although rare (~5%), lung metastases are possible and have an excellent prognosis
  2. The radiologic features of giant cell tumor (GCT) and giant cell reparative granuloma (GCRG) of bone often strongly suggest the diagnosis and reflect their pathologic appearance. At radiography, GCT often demonstrates a metaepiphyseal location with extension to subchondral bone
  3. Giant cell tumors in the spine are seen on radiographs or CT images as osteolytic, expansile lesions that have a thin shell of cortical bone at their margins (Figs. 36-1, 36-2, and 36-3). The cortical margin of the tumor is usually not sclerotic. Cortical marginal breakthrough may occur even with benign giant cell tumors (Figs. 36-2 to 36-5)
  4. Giant Cell Tumor Location: Long bones, metaepiphyseal, and eccentrical: distal femur, proximal tibia, and distal radius (65 % of the cases). Rare in the sacrum and pelvis
  5. Tenosynovial giant cell tumors are usually benign lesions that arise from the tendon sheath. It is unclear whether these lesions represent neoplasms or merely reactive masses. On imaging, these lesions are commonly demonstrated as localized, solitary, subcutaneous soft tissue nodules, with low T1 and T2 signal and moderate enhancement

Tenosynovial giant cell tumour is the term used in the latest (2013) World Health Organisation classification 10,11. They have previously been known as giant cell tumours of the tendon sheath (GCTTS) , pigmented villonodular tumour of the tendon sheath (PVNTS) , extra-articular pigmented villonodular tumour of the tendon sheath or localised or focal nodular synovitis 11 The radiologic features of giant cell tumor (GCT) and giant cell reparative granuloma (GCRG) of bone often strongly suggest the diagnosis and reflect their pathologic appearance Giant cell tumours of the tendon sheath (GCTTS) and pigmented villonodular synovitis (PVNS) are part of a spectrum of benign proliferative lesions of synovial origin that may affect the joints, bursae and tendon sheaths. This review article describes the clinicopathological features and imaging findings in patients with GCTTS

Subependymal giant cell astrocytomas (SGCAs or alternatively SEGAs) are benign tumors (WHO grade I), seen almost exclusively in young patients with tuberous sclerosis. They can be either asymptomatic or symptomatic due obstructive hydrocephalus, surgery treatment is often curative Some of the lesions originally diagnosed as giant-cell tumor have now been reclassified pathologically as aneurysmal bone cyst, benign chondroblastoma, fibroma, benign giant-cell reparative granuloma, unicameral bone cyst, osteogenic sarcoma, fibrosarcoma, and fibrous dysplasia The radiographic appearance of giant cell tumors is often characteristic. On radiographs, typical giant cell tumors are usually easily distinguished from other bone tumors. Giant cell tumors are.. Giant cell tumors involving the spine are rare. In a literature review by Shankman et al. [], only 2.7% of the 1,277 giant cell tumors reported were located in the spine.Sanjay et al. [] reported that from 1955 to 1990 there were only 24 patients with giant cell tumors of the spine at the Mayo Clinic.The tumor usually develops in the vertebral body, and the posterior elements are frequently.

Giant cell tumors commonly appear radiolucent and do not show periosteal reaction. 1 If the tumor is complicated by a fracture, there may be reactive bone formation. Some tumors may show areas of infarct or intravascular tumor emboli. Septa sometimes are seen and are caused by uneven tumor growth Giant cell tumors of bone: treatment with radiation therapy. Records of 15 patients with giant cell tumor of bone treated with radiation therapy over a 35-year period were reviewed; ten patients for whom follow-up information was available constituted the study group. One patient was treated by means of orthovoltage equipment only, a second, by. Giant cell tumor (GCT) of bone is generally a benign tumor composed of mononuclear stromal cells and characteristic multinucleated giant cells that exhibit osteoclastic activity. It usually develops in long bones but can occur in unusual locations Benign but locally aggressive primary bone neoplasm composed of mononuclear round to spindle cells with numerous evenly dispersed osteoclast-like giant cells Not the same tumor as giant cell lesion of the small bones Malignancy in giant cell tumor is rare (< 2% of cases) and is more common at older ages (30 - 50 years Shankman S, Greenspan A, Klein MJ, Lewis MM.

Radiologic studies of 50 giant cell tumors of bone in 48 patients were useful in assessing the anatomic extent for planning surgical treatment 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. However, if malignant degeneration does occur, it is likely to metastasize to the lungs

The most common type of localized TGCT is also referred to as giant cell tumor of the tendon sheath, which typically occurs as a localized nodule on the tendon sheaths of the fingers or toes. On the contrary, the diffuse type tends to infiltrate the joint, and more frequently involves large joints, most commonly the knee, followed by the hip Sonography is a helpful technique for diagnosing soft-tissue tumors in the extremities [].It is capable of distinguishing solid and cystic masses, determining whether a lesion is primarily vascular, guiding biopsies and aspirations, and defining the relationship of lesions to adjacent structures [].Giant cell tumor of the tendon sheath is one of the most common soft-tissue tumors in the hand.

Summary: A case of giant cell tumor of the thoracic spine simulating mediastinal neoplasm was identified on plain films, CT scans, MR images, and with scintigraphy. CT showed a hypervascular soft-tissue mass with shell-like calcification in the right upper mediastinum. MR imaging showed a collapse of the T1 vertebral body and a mass extending to the mediastinum 3 cell types (osteoclast-like giant cells, neoplastic cells and histiocytes) are present in most cases (~80%) Cytology has a diagnostic value for this tumor in ~80% of cases (Cancer Cytopathol 2017;125:563 Here is a case of peritendinous mass on the index finger most likely a tenosynovial giant cell tumor.

Giant cell tumor of bone is a locally aggressive, rarely metastasizing neoplasm. Evidence suggests that the neoplastic cells may be osteoblastic in differentiation. Standard treatment is surgical removal, but medical therapy with denosumab, an inhibitor of receptor activator of nuclear factor-κβ ligand, has become a component of patient.

Giant cell tumor is a locally aggressive neoplasm of uncertain origin which affects predominantly the epiphysis of long bones. It is so called because the tumor is predominated by the presence of multinucleated osteoclast like giant cells. It was also referred to as osteoclastoma for the same reason Imaging tests can help differentiate a tenosynovial giant cell tumor from other growths that produce similar swelling, such as fractures, joint injuries, infections, and inflammatory disease. These conditions tend to interfere with movement and cause more pain than tenosynovial giant cell tumors, but sometimes they can cause symptoms and an.
