Intraosseous lipoma is a very rare lesion, accounting for only 0.1% of all primary osseous tumors (1), first described in 1980 (2). This lesion is considered the rarest of benign bone tumors (3); probably it is not the actual incidence because these lesions are frequently asymptomatic and the introduction of cross-sectional imaging, especially MRI, seems to have increased the detection (4). The majority of intraosseus lipomas are in the lower limbs (70%) and the os calcis being the most frequently involved (32%)...

Vascular access is the most commonly performed invasive procedure in medicine. For more than 20 years, ultrasound has been shown to improve the success and decrease complications of central venous access; however, it is still not universally used for this procedure. Ultrasound may also be used to facilitate difficult peripheral vascular access, potentially avoiding other more invasive procedures such as central or intraosseus vascular access. This article reviews some of the indications and evidence for ultrasound-guided vascular access, provides tips for successful ultrasound guidance, and discusses barriers to adoption...

Solitary bone cysts (SBCs) are benign, intraosseus, cystic lesions, which generally involve metaphysis of long bones during the period of skeletal immaturity. Histologic features are nonspecific, but identification of amorphous cementum-like material provides a significant diagnostic clue. This material is unique to SBC with reported frequency of 10% to 70% and has been described as an immature form of bone. We retrieved and reviewed 41 cases of SBC reported in the last 10 years. The ages of patients ranged from 4 to 64 years (mean, 16 years), with a male-to-female ratio of 3:1...

Our aim was to evaluate the treatment given to patients with intraosseus ameloblastomas with special emphasis on recurrence and the outcomes of primary and secondary resection. Forty-eight patients who were treated for intraosseous ameloblastoma at 8 centres across Sweden met the inclusion criteria. They showed typical distribution of age, sex, site of lesion, and characteristic presenting features. Eleven of the 48 were initially treated with radical resection and none recurred. Twenty-two of the remaining 37 who were initially treated by conservative resection presented with recurrences...

We describe the case of a 23-year-old man whose CT scan revealed a hypodense lesion reshaping the superior and middle third of the clivus and partially invading the sphenoidal sinus. MRI showed an irregular-shaped lesion occupying the body of the sphenoid bone, involving the superior and middle third of the clivus and sprouting into the sphenoid sinus. The lesion was hyperintense on T1- and T2-weighted sequences with a thin peripheral rim of hypointensity, without enhancement after i.v. gadolinium injection...

BACKGROUND: Charcot neuroarthropathy is a severe complication in the feet of patients with diabetes, which can lead to a major amputation. Osteomyelitis and surgery for osteomyelitis have been reported as trigger mechanisms of developing Charcot neuroarthropathy. However, the development of acute Charcot neuroarthropathy triggered by osteomyelitis during conservative antibiotic treatment is not well outlined in the medical literature. CASE REPORTS: Two patients apparently developed mid and rear foot Charcot neuroarthropathy, which was clinically suspected while being treated with antibiotics for osteomyelitis...

Fibro-osseous lesions of the jaws can have certain histologic features in common with central giant cell granuloma (CGCG) including the presence of multinucleated giant cells. The clinical, radiologic and histologic features of these lesions should be carefully evaluated to distinguish between these conditions. Fibro-osseous lesions of the jaws are a heterogenous group of lesions characterized by the replacement of normal bone by fibrovascular tissue containing newly formed mineralized material. Central giant cell lesions are defined as an intraosseus lesion consisting of cellular fibrous tissue containing multiple foci of hemorrhage and aggregation of multinucleated giant cells...

BACKGROUND: Desmoplastic fibroma (DF) is an extremely rare locally aggressive bone tumor with an incidence of 0.11% of all primary bone tumors. The typical clinical presentation is pain and swelling above the affected area. The most common sites of involvement are the mandible and the metaphysis of long bones. Histologically and biologically, desmoplastic fibroma mimics extra-abdominal desmoid tumor of soft tissue. CASE PRESENTATION AND LITERATURE REVIEW: A case of a 27-year old man with DF in the ilium, including the clinical, radiological and histological findings over a 4-year period is presented here...

The venous and/or arterial vasculature may be accessed for fluid resuscitation, testing and monitoring, administration of blood product or medication, or procedural reasons, such as the implantation of cardiac pacemaker wires. Accessing the vascular system is a common and often critically important step in emergency patient care. This article reviews methods for peripheral, central venous, and arterial access and discusses adjunct skills for vascular access such as the use of ultrasound guidance, and other forms of vascular access such as intraosseus and umbilical cannulation, and peripheral venous cut-down...

Angiosarcoma (AS) is a rare non-epithelial malignant neoplasm arising from neoplastic vascular degeneration of endothelial cells. It usually occurs in soft tissue and skin. The incidence, according to American authors, is 1% of all soft tissue sarcomas. About 50% of AS is localized in head and neck region (scalp and face skin) and represents less than 1% of all malignancies of this district; the primitive intra- oral localization is rare, even rarer intraosseous development of AS in jaw bones. The Authors report a case of a mandibular intraosseus angiosarcoma with different peculiarities: the rarity of the location and mode of occurrence; in addition they have focused on clinical-histopathological and immunohistochemical charateristics...

BACKGROUND: In most cases, the natural healing of intrabony defects only leads to restoration of tissue continuity without differentiation and function. However, repair is not regarded to be an optimal treatment method, as confirmed in many clinical cases. Thus it is important to choose a surgical procedure which makes it possible to achieve restitution ad integrum of the bone structure. The choice of the GBR technique is crucial, in terms of the clinical conditions and limitations resulting from the use of a particular material...

Intraosseous hemangiomas are benign vascular tumors that are encountered most commonly in vertebrae and rarely in the skull. When presenting in the skull, they are commonly found in the calvarium in frontal and parietal bones and seldom in the skull base. We encountered a patient with an incidental finding on magnetic resonance imaging (MRI) of an enhancing lesion in the clivus. Here we report an unusual location of a clival intraosseous hemangioma. A 62 year old man worked up for carpal tunnel syndrome had imaging of his cervical spine that revealed an enhancing clival lesion, which extended into the left occipital condyle...

Solitary bone cyst (SBC) is an intraosseus radiolucent lesions that defers from real cysts for the fact that peripheral epithelial lining is totally absent. It could be classified as a psudocyst and occurs most frequently in young patients. In most cases SBC doesn't cause symptoms and it is often diagnosed accidentally during routine radiographic examination. A right diagnosis of this disease is also complicated because there are no pathognomonic radiographic signs and symptoms: so this form of pseudocyst is often misdiagnosed as a common odontogenic cyst...

Osteopoikilosis presents as round or ovoid sclerotic lesions with an appearance like enostosis on pathology. Synovial osteochondromatosis occurs due to cartilaginous metaplasia with synovial villous proliferation with calcified nodules in proximity to joints. A case of osteopoikilosis associated with synovial osteochondromatosis is described. Intraosseus and juxta osseus sclerotic bone lesions were identified on radiographs and computed tomography in a patient with knee pain. The association of osteopoikilosis with synovial osteochondromatosis is rare and to our knowledge has received little attention in the literature...
