Aneurysmal bone cyst is an uncommon bone lesion which rarely occurs in craniofacial region. Among all the cystic lesions occurring in the jaws, aneurysmal bone cyst is infrequent and it more commonly occurs in the mandible. Most of the cases occur in the first two decades of life, with no gender predilection. Here, we are presenting a case of an aneurysmal bone cyst which occurred in the mandib...

STUDY DESIGN The bone union rate after lumbar interbody fusion (LIF) using titanium (Ti) or polyetheretherketone (PEEK) cages was investigated retrospectively. OBJECTIVE To assess whether the PEEK cage is superior to the Ti cage in terms of bone union after LIF. SUMMARY OF BACKGROUND DATA We previously reported that the formation of vertebral endplate cysts is useful for predicting nonunion...

Aneurysmal bone cyst, first described by Jaffe and Lichtenstein I in 1942 as a rare, localized tumor of the long bones and spinal vertebrae, characterized by the "blowout distention" of the skeletal contour on a radiograph.2 This neoplasm, usually found in children and young adults, constitutes 1.4 percent of all primary bone tumors.3 The cyst is occasionally associated with other tumors of the...

MR findings in a case of aneurysmal bone cyst of the temporal bone are described. MR can suggest the diagnosis of aneurysmal bone cyst and also give ancillary information that is helpful for surgical treatment.

Chondroblastoma of the patella is rare. Aneurysmal bone cysts, which develop from a prior lesion such as a chondroblastoma, are seldom seen in the patella. The authors report a case of a 36-year-old man who presented with 2 years of right knee pain without calor, erythema, pain on palpation, or abnormal range of motion. Radiological studies suggested aneurysmal bone cyst. The lesion was excised...

BACKGROUND Simple bone cysts (SBC) have been documented to occur in adults with closed physeal plates, most commonly affecting the calcaneus in this patient subset. Although most authors theorize an association to trauma, etiology of simple bone cysts remains an enigma up to now. CASE PRESENTATION A 26-year-old kickboxing coach sought consult for a painful right shoulder which on radiographs ...
