• Article: Classic adamantinoma in a 3-year-old.

  [show abstract] [hide abstract]
  ABSTRACT: Classic adamantinoma of the long bones is a rare, low-grade malignant neoplasm arising most often in the tibia and usually in patients during the second to fifth decades. Although adamantinomas have been described in children, the histologic pattern in this age group is different from that seen in adults and resembles osteofibrous dysplasia. The usual pattern of adamantinoma in children has been termed "differentiated adamantinoma" and follows a benign course. We report a case of adamantinoma in the proximal tibia of a 3-year-old patient. The lesion had abundant epithelial component with formation of keratin pearls, a pattern that has been described only in classic adamantinoma occurring in adults. Since differentiated adamantinomas are essentially benign and classic adamantinomas are low-grade malignancies, the finding of a classic variant at this young age raised important therapeutic and prognostic issues.

  Article: Traumatic isolation of the cervical articular pillar: imaging observations in 21 patients.

  [show abstract] [hide abstract]
  ABSTRACT: Imaging studies of patients diagnosed with traumatic isolation of a cervical articular pillar were retrospectively reviewed to better understand the mechanism, clinical significance, and management requirements of this injury. Imaging studies obtained before definitive treatment of 21 patients with traumatic isolation of a cervical articular pillar were reviewed to determine the level and mechanism of injury, fracture patterns, and associated fractures. Lateral cervical radiographs and axial and reformatted sagittal cervical CT images were obtained for all patients. Medical records were reviewed to ascertain the neurologic deficit, if any, and clinical management. Traumatic isolation of a cervical articular pillar was diagnosed at 24 levels in the 21 patients. The imaging studies indicated that the injury mechanisms producing isolation of the articular pillar were hyperflexion-rotation in 17 patients (81%), hyperflexion-distraction in three patients (14%), and hyperextension-rotation in one patient (5%). A fracture through the transverse foramen ipsilateral to the isolated articular pillar was observed in 19 patients (90%). Contralateral injuries at the level of the isolated articular pillar were present in 14 patients (67%). Neurologic deficits were present in 13 patients (62%) and included spinal cord injury (10) and radiculopathy (3). Eighteen patients underwent surgical reduction and internal stabilization. On the basis of an analysis of cervical radiography and CT findings, cervical spine fractures resulting in isolation of an articular pillar most commonly occur from hyperflexion-rotation or hyperflexion-distraction mechanisms. Previous literature has indicated that cervical hyperextension is responsible for this injury, but hyperextension accounted for only one case in this series. It is important to identify the isolated cervical articular pillar as a component of other cervical fracture patterns, as the injury creates two levels of mechanical instability requiring internal fixation of three contiguous vertebrae.

  Article: Rotational injury of cervical facets: CT analysis of fracture patterns with implications for management and neurologic outcome.

  K Shanmuganathan, S E Mirvis, A M Levine
  [show abstract] [hide abstract]
  ABSTRACT: Imaging studies of patients with rotational facet injuries of the cervical spine were retrospectively reviewed to determine the prevalence and pattern of associated fractures, to correlate injury pattern with recommended surgical stabilization, and to assess neurologic outcome. Radiographs and CT scans obtained for 40 consecutive patients with rotational facet injuries of the cervical spine during a 70-month period were retrospectively reviewed to determine injury level, presence, and orientation of facet fractures, and concurrent nonfacet injuries. Imaging findings were reviewed to assess the likelihood of instability and to determine the most appropriate stabilization requirement. Medical records were reviewed to ascertain mechanism of injury, initial neurologic deficit, and surgical findings. Among the 40 patients with cervical rotational facet injuries, 11 (27%) had pure unilateral facet dislocation or subluxation without associated fractures, and 29 (73%) had concurrent facet fractures involving the inferior facet of the rotated vertebra (n = 13), the superior facet of the subjacent vertebra (n = 9), or both (n = 7). Injury of the rotated vertebra was unilateral in 22 patients but bilateral in 18 patients. Facet fractures frequently extended into the ipsilateral lamina or articular pillar or both. An avulsion fracture from the posteroinferior aspect of the rotated vertebral body, indicating disk disruption, occurred in 10 patients (25%), and seven patients (17%) had complete isolation of an articular pillar. Facet fractures were confirmed for 27 patients who underwent surgical stabilization. Neurologic deficits developed in 29 (73%) of the 40 patients and included radiculopathy in 11 patients and cord syndromes in 18 patients. Pure dislocation without a facet fracture was more likely to lead to a cord syndrome (p = .006). Cervical rotational facet injuries are often accompanied by facet fractures and bilateral damage of the rotated vertebra. These injuries contribute to rotational instability and require specific internal fixation based on a precise delineation of all injuries. Facet dislocations without fractures have a significantly higher association with cord syndromes than do rotational facet injuries with fractures. CT, particularly with parasagittal reformations, is valuable in identifying all injuries of the rotated and subjacent vertebrae.

• Article: Case report 660: Adamantinoma of tibia.

  [show abstract] [hide abstract]
  ABSTRACT: An adamantinoma of the tibia is presented, for which the CT and MRI characteristics are described. Both imaging modalities were excellent in providing information as to the extent and invasiveness of the tumor, although MRI had the advantage of providing immediate high quality sagittal visualization. Comparison is made briefly between adamantinoma and both fibrous dysplasia and osteofibrous dysplasia.

• Article: Vascular metastatic lesions of the spine: preoperative embolization.

  F E Gellad, N Sadato, Y Numaguchi, A M Levine
  [show abstract] [hide abstract]
  ABSTRACT: Preoperative embolization of vascular metastatic tumors of the spine, particularly carcinomas of renal and thyroid origin, is an adjuvant technique that significantly decreases the intraoperative blood loss and resultant surgical morbidity. Surgical decompression was achieved in 24 spinal vascular metastatic lesions, 20 of which were treated with preoperative embolization and four of which were not. The embolic materials used were gelatin sponge, polyvinyl alcohol foams, and metallic coils. In patients who underwent adequate embolization, an average of 1,850 mL of estimated blood loss was reported; in those who underwent inadequate or no embolization, greater than 3,500 mL of estimated blood loss occurred. When gelatin sponge is used, surgery should be performed within 24 hours to prevent preoperative recanalization.

  [show abstract] [hide abstract]
  ABSTRACT: Desmoplastic fibroma of bone is a rare benign tumor, first described by Jaffe in 1958. Since then approximately 80 cases have been reported in the long bones, although the tumor also involves the jaw bones, particularly the mandible. The plain film features consist of a lytic, expansile lesion, usually in the metaphysis of bone, sometimes extending into the soft tissues. We present two cases involving the long bones in which the correct diagnosis was suggested by computed tomography (CT). The CT appearance of the lesions is described.
