In recent years, CT-guided RFA has replaced en bloc surgical resection as the standard of care in the majority of cases of osteoid osteoma
. (2,3) Recurrence rates for surgery and RFA are comparable at 9% and 12% respectively, and rates of residual symptoms are similar at 30% and 23% respectively.
of stapes in the middle ear: a case report.
Recurrence rate is less than 10% with power burr.8 A new non-invasive radiation-free method is under observation - magnetic resonance guided focussed ultrasound ablation technique - which focuses ultrasound waves on osteoid osteoma
is a benign tumor that commonly affects male adolescents and young adults.
generally present as slowly growing lesions of bone and are among the most common lesions of the nose and paranasal sinuses.
presents with pain in 80% of patients; often, this pain is worse at night and relieved with salicylates or other nonsteroid anti-inflammatory agents .
(18) showed that malignant lesions, such as osteosarcoma and Ewing's, as well as benign finding, such as osteoid osteoma
and stress fractures, may show marrow edema or peritumoral edema.
Tumors of bones of jaw include odontogenic tumors, osteoma
, fibroma, fibrosarcoma and myxomatous tumors.
MRI is an additional useful modality that can help distinguish fibrous dysplasia from meningioma, osteoma
or mucocele and define the extent of soft tissue involvement, particularly if central nervous system structures are impinged on.
In addition, differential diagnosis should include periostitis, medial tibial stress syndrome, tibial stress reaction, anterior compartment syndrome, infections, tumors (i.e., osteogenic sarcoma, Ewing's sarcoma, and osteoid osteoma
) and metastases.
Dentro de los tumores que forman hueso y que tienen una orientacion benigna se encuentran el osteoma
osteoide y osteoblastoma (Tecualt et al., 2008).
Three of the 30 cases (10%) were clinically useful but not accurate: (1) a 4.6-cm tibial lesion diagnosed as spindle cell sarcoma by FNACBP with a subsequent diagnosis of MPNST on resection, (2) a 1.9-cm benign spindle cell acetabular lesion with a subsequent diagnosis of benign bone cyst on excision, and (3) a 3.7-cm frontal sinus, benign osteoblastic lesion subsequently diagnosed as a cranio-facial osteoma
with osteoid osteoma-like nidus on excision.
Peripapillary CNVM are also known to occur with other diseases including ocular histoplasmosis (OHS), angioid streaks, pars planitis, optic disc drusen, choroidal osteoma
, and pattern dystrophies .
is a rare benign intraocular tumor characterized by heterotopic bone of the choroid.
(OO) is the most common benign osteogenic bone tumor that predominantly affects young adults.
