Computed tomography-guided percutaneous trephine removal of the nidus in osteoid osteoma patients: experience of a single center in Brazil

Abstract

ObjectiveTo report the results of computed tomography (CT)-guided percutaneous resection of the nidus in 18 cases of osteoid osteoma.Materials and MethodsThe medical records of 18 cases of osteoid osteoma in children, adolescents and young adults, who underwent CT-guided removal of the nidus between November, 2004 and March, 2009 were reviewed retrospectively for demographic data, lesion site, clinical outcome and complications after procedure.ResultsClinical follow-up was available for all cases at a median of 29 months (range 6–60 months). No persistence of pre-procedural pain was noted on 17 patients. Only one patient experienced recurrence of symptoms 12 months after percutaneous resection, and was successfully retreated by the same technique, resulting in a secondary success rate of 18/18 (100%).ConclusionCT-guided removal or destruction of the nidus is a safe and effective alternative to surgical resection of the osteoid osteoma nidus.

Atypical Proximal Femoral Osteoid Osteoma

“…Osteoid Osteoma can present in unusual way and a high index of suspicion is essential for appropriate management. These types of lesions when confirmed can be treated with computed tomography-guided percutaneous trephine removal of the nidus [10], demonstrating that this is safe and effective method for surgical resection of the lesion with reduced hospitalization time and less post-operative pain [11].…”

“…The plain radiograph shows the pathognomonic pattern of central radiolucency with surrounding sclerosis, and classically the pain is relieved with NSAID's, ours case did not show any of these classical findings making diagnosis more difficult. Computed tomography is an excellent imaging method to identify the central nidus of the tumor and can also be utilized for treatment, as guidance for percutaneous removal of the nidus as described by the article developed by Petrilli et al [11].…”

Osteoid Osteoma in acromion of scapula: a case report

“…Osteoid osteoma can occur in any bone. It predominantly involves the cortex of shaft of long bones of lower limbs (90%) [3]. It rarely affects the scapula and only few cases have been reported in literature.…”

Imaging evaluation of bone tumors

“…If necessary, CT can be helpful in determining the pattern of calcification in the matrix of the lesion, in identifying occult bone destruction, or even in localizing the nidus of an osteoid osteoma ( 1 , 2 ) . It can also serve to guide the collection of tissue for histological analysis ( 4 ) and less invasive treatments of certain tumors, such as osteoid osteoma ( 5 ) .…”
