Spinal Osteoid Osteoma Associated With Soft Tissue Changes as a Challenging Diagnosis: A Review of the Literature

et al. 2016

Context: Spinal osteoid osteoma (OO) is an infrequent tumor and due to both its smallness and complex anatomy of the spine diagnosis is challenging. In addition, associated undefined soft tissue changes on magnetic resonance imaging (MRI) frequently cause misdiagnosis. Evidence Acquisition: PubMed database was searched for "spinal osteoid osteoma" and larger clinical series related to clinical pictures, diagnosis or treatment modalities, and also case reports with especially soft tissue changes and related to special treatment modalities were introduced to the study. It was aimed at to make conscious practitioners of clinical and diagnostic characteristics of spinal OOs. Results: Spinal OOs constitute about 10% of OOs and the most of the tumors are seen in adolescents or young adults. The most frequent clinical picture is painful scoliosis or torticollis according to the level of the tumor. On MRI that is the most frequently performed imaging modality in the patients with painful scoliosis, undefined extensive bone and soft tissue changes is quite frequent. Clinicians must be aware from these findings and they must suspect and investigate the patients with bone scintigraphy and thin sectioned computerized tomography that both of them together can show presence of the lesion and provide to determine exact location of the lesion. Despite the increasing number of the studies using percutaneous ablation techniques, standard treatment of spinal OOs is still intralesional excision. Surgical excision usually provides immediate pain relief, and recurrence is not frequent. Conclusions: Diffuse paravertebral muscle and soft tissue involvement having resemblance to myositis is not quite rare in the patients with spinal OO. This may be the sole finding on MRI and it must be alert for the clinicians to look for small OO nidus by bone scintigraphy or thin sectioned CT scan.

“…[28][29][30][31] Previous research has confirmed the protective nature of cortical bone between the RFA probe and adjacent soft tissues 27,32 and that there is limited transfer of heat to the vertebral canal. 33 Although thermoprotective measures in the spine have been described, 34 there is no in vivo (or in vitro) evidence that these do in fact serve to provide additional protection for neural structures.…”

Radiofrequency ablation of osteoid osteoma: Aiming for excellent outcomes in an Australasian context

et al. 2018

Introduction To report a series of patients with osteoid osteoma treated by radiofrequency ablation in whom no complications or recurrences occurred. Methods Over a 13‐year period, 32 consecutive patients with osteoid osteoma were treated by radiofrequency ablation in an Australasian teaching centre. Results All patients had resolution of symptoms with no complication or recurrence. Conclusions This series is further evidence for the use of radiofrequency ablation as the primary treatment for osteoid osteoma.

“…Morassi et al reported VAS decrease from 8.6 to 0 for their 11 patients after the procedure. Two of patients were considered as recurrence and after second procedure their VAS reduced to 0 as well [ 23 ]. In our study VAS reduction for both day and nighttime was statistically significant.…”

SummaryBackgroundThe aim of this retrospective study is to determine our experience of technique success rate, complications and clinical results in long term follow up for computed tomography (CT)-guided radiofrequency ablation [RA] therapy for osteoid osteoma (OO).Material/MethodsWe performed RA therapy to 18 patients with OO referred to interventional radiology from other clinics primarily from orthopedics; between January 2011 to May 2014. Daytime and nighttime pain intensity of 18 patients was noted according to visual analog scale (VAS). After procedure pain intensity was compared with before one. We also discussed other factors can affect it.ResultsAll procedures were completed technically successful for all patients [100%]. We did not experience any major complication or mortality. However we had 3 minor complications. Pain came back in 1 patient after 5 months from procedure and it was considered as recurrence. Dramatic pain intensity fall was seen in patients after procedure, both daytime and nighttime. However we did not find and statistically significant change in comparison of pain intensity reduce and time needed to return back to routine life when using patients demographic data and lesion size.ConclusionsCT guided RA therapy of OO is minimally invasive, effective and secure procedure.
