C n 1942, Stafne was the first to report the presence of one cavities in 35 patients. These usually create a ell-demarcated radiolucency in the posterior manibular angle and are synonymously known under ifferent names in the literature: Stafne bone cyst, tatic bone cavity, latent bone cyst, lingual mandibuar bone cavity, mandibular embryonic defect, idioathic bone concavity of the mandible, and...

Abstract Ligamentum flavum cyst of the lumbar spine has seldom been described. The mechanism formation these cysts remains unknown, but it is thought to be part degenerative process. Although they are clearly visible on imaging studies, frequently wrongly diagnosed as ganglion or synovial cysts. Bone erosion rarely associated with this pathology. Most common symptom back and radicular pain due ...

Introduction. This paper describes a case of bone augmentation with combination of Platelet-Rich Fibrin (PRF) and β-TCP for treatment of chronic periapical cyst. The case was followed for 12 months. Methods. Patient presented with chronic periapical lesion in maxillary anterior teeth with history of trauma 8 years back. Radiographically, a periapical cyst was seen in relation to maxillary left ...

The internal pressure of simple bone cysts was found to be slightly higher than the normal pressure of the bone marrow in the contralateral limb. The pressure within the cyst was measured during drilling with a Kirschner wire; it gradually decreased as the number of drill-holes increased. The PO2 of the cyst fluid was markedly lower than that of either venous or arterial blood measured synchron...

aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...

The aim of this study was to present the results of non-vascularized fibular graft for reconstruction of bone defects after en block resection of giant aneurysmal bone cyst (ABC) of the extremities. Between 1998 and 2006, three patients, aged 6, 8 and 23 years, with giant aneurysmal bone cysts were treated. The cysts were located in the humerus, proximal femur and metatarsal. All patients were ...

We report the case of a 40-year-old man presenting with focal headache and a bulge at the right parietal bone, diagnosed as an intradiploic arachnoid cyst. The cyst wall included "meningothelial hyperplasia," which is a rare finding. While over 40 cases of intradiploic arachnoid cysts have been reported to date, meningothelial hyperplasia in an intradiploic arachnoid cyst does not appear to hav...

a 48-year-old man referred with pain and swelling at the upper and middle third of left tibia with a history of previous os­seous hydatid disease three years ago. despite surgical procedure which was performed in this case, recurrence was ob­served and repeated exploration with wide resection and oral medical therapy were recommended. bone hydatid cyst is an uncommon disease with difficult resp...

Radicular cystsare common odontogenic cyst of jaw bone which invariably presents as welldefined radiolucency around the apex of the involved tooth. It is diagnosed on routine radiography or causes a slow growing swelling, limited to apical region of a tooth. Radicular cyst presenting as unusually large maxillary lesions is uncommon. This paper reports two cases of large radicular cyst involving...
