Aneurysmal Bone Cysts of the Spine: Two Case Reports

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically. Most cases have uncommon pain symptoms, but rarely, if fract...

Unusual localizations of unicameral bone cysts and aneurysmal bone cysts: A retrospective review of 451 cases.

Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 20...

Aneurysmal bone cysts. Review of twelve cases.

The bone cysts of osteoarthritis.

Rounded areas of translucency in the bones forming an osteoarthritic joint are well known to radiologists and to orthopaedic surgeons. They are not given much prominence in pathological accounts : their formation is vaguely ascribed to degeneration in the bone in keeping with the degeneration in the neighbouring cartilage. Their frequency was given by Plewes (1940), from clinical and radiologic...

Cannulation of simple bone cysts.

We describe a consecutive series of 26 patients with simple bone cysts who were treated by curettage, multiple drilling and continuous decompression by the insertion of either a cannulated screw or a pin. In the first 15 patients we used titanium cannulated screws (group 1) and in the next 11 a cannulated hydroxyapatite pin (group 2). Satisfactory healing was achieved in 12 patients in group 1 ...

MR imaging of epidermoid cysts.

Nine patients with epidermoid cysts, five of them pathologically proved, were evaluated with MR imaging. Six patients also had CT. The cases were reviewed to evaluate the MR appearance of epidermoid cysts and to compare the MR findings with those of CT. The epidermoid cysts demonstrated low-signal intensity on T1-weighted MR images and hyperintensity on T2-weighted images. In five cases the cys...
