11/184. Osteoid osteoma of the spine treated with percutaneous computed tomography-guided thermocoagulation.STUDY DESIGN: Two cases are reported in which an osteoid osteoma of the lumbar spine was treated with CT-guided thermocoagulation. OBJECTIVES: To review an alternative and minimally invasive treatment for spinal osteoid osteomas. SUMMARY OF BACKGROUND DATA: Surgical resection of a spinal osteoid osteoma can, depending on the location, be a formidable undertaking. Bone scintigraphy can be helpful in intraoperative identification. More recently, resection through a computed tomography-guided drill hole was found to minimize exposure. Using a thermocoagulation probe, as has been used in osteoid osteoma of the extremities, may be technically easier and cause less morbidity. METHOD: With the patient under general anesthesia, a bone biopsy cannula was introduced into the center of the osteoid osteoma. Material was subjected to histologic examination. A thermocoagulation probe was then inserted and heated to 90 C for 4 minutes. The two patients were kept overnight for observation. RESULTS: Both patients had complete pain relief and no evidence of recurrence after 2 years' follow-up. There were no complications. scoliosis resolved in one patient and persisted in the other. CONCLUSION: Percutaneous computed tomography-guided thermocoagulation is a minimally invasive and technically straightforward method to achieve ablation of a spinal osteoid osteoma. No complications were encountered in these two patients. Future research should focus on the safety of thermocoagulation, especially cephalad to the level of the conus medullaris.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
12/184. Painless osteoid osteoma of the finger in a child. Case report.The authors report the case of an 8-year-old child presenting with painless swelling of the middle phalanx of the ring finger. radiology demonstrated simple hypertrophy of cortical bone with a clear zone. Bone biopsy showed the typical features of osteoid osteoma. Osteoid osteoma is rarely painless and generally corresponds to a superficial tumour (hand, foot, skull and thorax).- - - - - - - - - - ranking = 2keywords = pain (Clic here for more details about this article) |
13/184. Percutaneous CT guided resection of osteoid osteoma of the tibial plafond.Osteoid osteomas of the foot and ankle are relatively rare and notoriously difficult to diagnose. Juxta-articular osteoid osteomas are more difficult to treat and often have a significant delay in diagnosis. We report a case of a juxta-articular osteoid osteoma of the tibial plafond. Once the diagnosis was made, excisional biopsy was performed percutaneously under computed tomography (CT) guidance as an outpatient in the radiology suite. The patient had complete resolution of symptoms and remains pain free at two years follow-up. CT guided resection can be a lower morbidity and more cost effective technique to treat this lesion than traditional methods.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
14/184. Primary bone tumors of the femur presenting with spinal symptoms: a report of two cases and review of the literature.Two case reports of femoral bone lesions simulating lumbar spinal disease are presented. physical examination and case history were strongly suggestive of lumbar spinal pathology. In case 1, surgical resection of a venous hemangioma in the lumbar epidural space was performed but did not relieve pain. In case 2, conservative treatments for a protruded disk were performed for 3 months before an accurate diagnosis was made. After correct diagnoses were made, excision of the femoral tumors brought rapid relief of all abnormal findings in both cases. Compared with other causes of sciatica, femoral bone tumors are rare. However, careful attention should be paid to rule out these lesions if the diagnosis of a lumbar spinal disease is uncertain. Bone scintigraphy seems to be a sensitive diagnostic method to detect extraspinal osseous lesions.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
15/184. Computed tomography-guided endoscopic removal of an osteoid osteoma from the femur.The case of a 19-year-old male patient who complained of dull pain in his right knee for more than 18 months and was finally diagnosed with intracortical osteoid osteoma in the femoral diaphysis is presented. A new operative method was used to locate and remove the tumor. Under spinal anesthesia with the patient in the prone position, a lateral and a posterior approach were marked with special bone cutting tubes under computed tomographic control. The usual arthroscopic instruments (punch, retrograde suction stamp) were used to remove the nidus under arthroscopic visualization, thereby avoiding the disadvantages of open excisions, such as large incisions, bone loss, long hospitalization, and risk of infection. The advantages and disadvantages are thoroughly discussed and compared with conventional surgical procedures.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
16/184. Osteoid osteoma of the carpal bones.Osteoid osteoma is a benign bone tumor that rarely localizes in the hand or the carpal bones. We report two cases of osteoid osteoma localized in two different carpal bones. Unremitting wrist pain was a major clinical symptom. Surgical treatment including excision of the nidus was dramatically curative. In young patients, osteoid osteoma should be considered in the differential diagnosis of chronic wrist pain.- - - - - - - - - - ranking = 2keywords = pain (Clic here for more details about this article) |
17/184. Osteoid-osteoma of the radius. Report of a case.This case is a report of a 9-year-old boy with an osteoid osteoma in the distal radius, an unusual location. The tumor was remarkably large in size, and pain unrelieved by aspirin. Osteoid-osteomatat have been described in just about every bone in the skeleton. lower extremity involvement is more frequent than upper in all series and incidence is much higher in males than in females. pain is the major complaint, both night and day. The response to aspirin is variable. The diseases is most frequently encountered in the second decade of life.- - - - - - - - - - ranking = 1.0018433725798keywords = pain, upper (Clic here for more details about this article) |
18/184. Osteoid osteoma of the lunate--a case report.We report a rare case of an osteoid osteoma of the lunate bone in a young lady who presented to us with chronic wrist pain.

19/184. Chronic persistent knee pain after repeated diagnostic arthroscopy: osteoid osteoma, a primarily overlooked diagnosis in a young woman.We report a case of osteoid osteoma of the distal femur in an adolescent female patient that was primarily overlooked and led to repeated diagnostic arthroscopy of the knee. A thorough history and physical examination of the joint as well as adequate roentgenographic studies could have spared this patient two unnecessary arthroscopies and indicated the correct therapy.- - - - - - - - - - ranking = 4keywords = pain (Clic here for more details about this article) |
20/184. A painless subungual osteoid osteoma.BACKGROUND: Osteoid osteoma is a benign bone tumor. Its etiology is not fully understood and the role of trauma is still elusive. OBJECTIVE: Osteoid osteoma mostly presents with a poorly localized pain that is worst at night and characteristically relieved by salicylates. It usually occurs on the weight-bearing bones of the lower extremities, but toe location is quite rare. Here, we present a case of painless osteoid osteoma located subungually on the dorsum of the great toe. RESULT: A 29-year-old woman presented with a painless subungual mass on the dorsum of her great toe. Subungual exotosis, osteochondroma, and osteoma were considered in the differential diagnosis and the lesion was totally excised. Histopathologic examination showed characteristic findings of osteoid osteoma. CONCLUSION: A painless osteoid osteoma is rarely seen and it can be easily misdiagnosed if it occurs in an atypical location such as the subungual area.- - - - - - - - - - ranking = 8keywords = pain (Clic here for more details about this article) |
