osteoma/edema

OBJECTIVE To determine whether there is a relationship between the peritumoral edema caused by osteoid osteoma seen on magnetic resonance (MR) imaging and the patient's age, duration of symptoms, or location of the lesion. METHODS All histologically proven osteoid osteomas seen in our institutions

This case report describes a well-documented birth and evolution of an osteoid osteoma at the talus. Although initial radiologic images indicate mild bone marrow edema at first (without nidus), subsequent magnetic resonance imaging and computed tomographic images reveal pathognomonic nidus at the

Four cases of osteoid osteomas are presented. An uncharacteristic magnetic resonance finding of soft tissue edema is reported. This observation should not be misinterpreted as indicating a more aggressive pathologic process and, thereby, exclude osteoid osteoma from the differential.

Osteoid osteoma (OO) is a benign bone tumor producing non-mineralized bone matrix (i.e., osteoid). While peritumoral edema is commonly found in OO, extensive bone marrow edema has been reported less frequently. Furthermore, the micro-morphological characteristics of the nidus and its central

Osteoid osteoma (OO) is a benign skeletal neoplasm. Twenty-eight patients with proven OO were studied with MRI regarding soft tissue involvement which was diagnosed when high proton-density and T2-weighted signal intensity and low signal intensity on T1-weighted images were found close to bone. Most

The purpose of this study was to determine magnetic resonance imaging (MRI) features of osteoid osteomas and to evaluate the place of MRI in the diagnostic workup of suspected osteoid osteoma by comparing its diagnostic value with that of computed tomography (CT). Nine patients with radioclinical

Approach to loss of visual acuity in a patient with a choroidal osteoma (CO) which had been stable for seven years. Fluorescence angiography confirmed a choroidal neovascularization (CNV) as the cause of the loss of visual acuity. Treatment with intravitreal (IVT) injection of ranibizumab. Increase

We present the case of a 59-year-old male patient with unrecognized osteoid osteoma in radiography as well as in magnetic resonance imaging. Computed tomography revealed osteoid osteoma that was successfully treated with percutaneous computed tomography guided radiofrequency ablation. The osseous

Coracoid osteoid osteomas are rare. This case report presents two patients with coracoid osteoid osteomas who developed neurologic sequelae of the infraclavicular brachial plexus (namely, musculocutaneous neuropathy in one patient with an anterior lesion, and suprascapular neuropathy in the other

A 32-year-old man had a history of acquired Brown's syndrome associated with diplopia, proptosis, downward displacement of the globe, and lid edema. A CT scan of the orbit revealed an osteoma arising from the left frontal sinus and extending into the left orbit. After surgical extirpation the

OBJECTIVE To report our experience pertaining to three cases of intra-articular osteoid osteoma assessed by means of integrated imaging and review of literature. METHODS Medical records, radiologic and nuclear medicine findings pertaining to three cases of intra-articular osteoid osteoma were

A 12-year-old girl had blurred vision and pain behind her left eye for three months. An examination disclosed focal choroiditis and optic nerve edema. Her visual acuity was 20/30. Two similar previous episodes had been diagnosed as scleritis and uveitis and the patient was still on a regimen of 5 mg

We report the case of an 8-year-old boy who presented an osteoid osteoma of L5 associated with bilateral spondylolysis involving the same vertebra. Diagnostic bone scintigraphy is highly contributive in children presenting back pain. For us, it is the first intention exploration in patients with
