Chondroblastoma: classic and confusing appearance at MR imaging.

Abstract

Knowledge of the MR imaging findings of chondroblastoma will allow accurate diagnosis and help avoid confusion with infection and aggressive neoplasms.

Clear cell chondrosarcoma mimicking chondroblastoma in a skeletally immature patient

“…Thus, CCCS has not traditionally been included in the differential diagnosis of epiphyseal lesions in skeletally immature patients. In addition, the finding of significant marrow edema on MRI, as in our case, is felt to be a frequent finding with chondroblastoma [10,11] but not CCCS [9]. This case highlights the rare occurrence of CCCS as an epiphyseal lesion in a skeletally immature individuals, indistinguishable on imaging from chondroblastoma.…”

“…A sharp interface between bone and tumor was usually present, though sclerotic and indistinct borders have also been described [1,3]. MRI scans characteristically do not demonstrate edema around the lesion [9] as opposed to certain benign bone tumors, to include chondroblastoma [10,11].…”

“…Because of its epiphyseal location, distinct borders and occasional calcifications, CCCS is known to mimic chondroblastoma [11,14]. However, CCCS most commonly occurs in the third to fifth decade, whereas chondroblastoma occurs in the first and second decades [3,12].…”

Condroblastoma de escafoides carpiano

“…En nuestro caso las característi-cas de imagen (Rx, TAC y RM) fueron similares a las descritas habitualmente en otras localizaciones más habituales de tumores benignos condroides 1,2,4,[7][8][9][10] . Los rasgos histológicos eran los descritos típicamente en el condroblastoma: nódulos de matriz cartilaginosa rodeados por un tejido de alta celularidad, relativamente indiferenciado, constituido por células redondeadas u ovoides semejantes a los condroblastos y por células gigantes multinucleadas de tipo osteoclástico aisladas o en grupos , así como pequeñas zonas de calcificación focal 2,7 .…”

Chondroblastoma with Secondary Aneurysmal Bone Cyst in the Sphenoid Sinus: A Case Report

“…Additionally, endosteal scalloping can be seen on CT or plain radiography (6, 7). On MRI, the surrounding bone marrow and soft tissue edema are seen in a large proportion of the reported cases (8). Also, secondary aneurysmal bone cysts There is no consensus on the standard treatment option for chondroblastoma arising from the skull.…”
