2025年1月27日 · Plain radiographs are the first-line imaging modality. CT and MRI add little to the diagnosis, however, can be helpful in eliminating other entities that can potentially mimic a simple bone cyst (see differential diagnosis below) 8.

2025年2月25日 · MRI can demonstrate the characteristic fluid-fluid levels exquisitely, as well as identify the presence of a solid component and concerning features suggesting an aneurysmal bone cyst-like appearance of another tumor entity. The cysts are of a variable signal, with a surrounding rim of low T1 and T2 signals.

CT and MRI are only helpful in selected cases. Here are links to other articles about bone tumors: Approach. Most bone tumors are osteolytic. The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1).

It provides useful information for diagnosis of the lesion as in primary or secondary aneurysmal bone cyst, chondroblastoma, osteoblastoma, fibrous dysplasia, and osteofibrous dysplasia, and it helps differentiate these lesions from osteomyelitis, …

We then discuss the imaging appearance of ABC by focusing on radiographs, magnetic resonance imaging (MRI) and computed tomography (CT) as well as the differential diagnosis, specifically telangiectatic osteosarcoma, which is a true mimicker of ABC.

2011年1月1日 · In this article we will discuss the differential diagnosis of well-defined osteolytic bone tumors and tumor-like lesions. On the left the most common well-defined bone tumors and tumor-like lesions. These lesions are sometimes referred to as benign cystic lesions, which is a misnomer since most of them are not cystic, except for SBC and ABC.

2022年7月20日 · MRI is the best imaging choice to distinguish these tumors and surrounding structures. MRI usually detects the multiple blood-filled cystic spaces with fluid-fluid levels and septations separating the cysts. What are the histopathologic characteristics of …

2023年7月4日 · On magnetic resonance imaging (MRI), the cystic composition of the lesion is confirmed on fluid-sensitive sequences (high signal intensity) and are of low to intermediate signal intensity on anatomic sequences. The rim may enhance 80% of the time on postcontrast imaging. Less commonly seen is a central enhancement of the bone cyst (27%).

Magnetic resonance imaging is considered the modality of choice for evaluation of other benign musculoskeletal lesions because it is highly sensitive to changes in the signal intensity of bone marrow and adjacent soft tissues.

Bone cysts in the pediatric population are often found incidentally on radiographs or after a cyst has created cortical weakness leading to a pathologic fracture. Most bone cysts are benign, are pain free, and resolve spontaneously. The most common bone cyst is unicameral 1-chamber bone cyst, also known as simple bone cyst.
