Anteroposterior diameter of the vertebral canal in cervical region: comparison of anatomical, computed tomographic, and plain film measurements.

The purpose was to compare the computed tomographic and plain film measurements with those of anatomical specimens to determine the antero-posterior diameter of the spinal canal in cervical region. Antero-posterior diameters of 75 cervical vertebral canals (15 sets of C3-C7) were measured anatomically at two different levels. Computed tomographic and plain film measurements were also obtained at the corresponding levels. Considering anatomical measurements as the gold standard, plain film and computed tomographic measurements were statistically compared. Interobserver and intraobserver differences were also evaluated. At the uppermost pedicle levels, there was no statistically significant difference between plain films and anatomical measurements, a good correlation. However, at lowermost pedicle level there was a statistically significant difference between plain films and anatomical measurements but not between tomographic and anatomical measurements. Our results suggest that plain films can accurately estimate cervical spinal canal mid-sagittal diameter at the uppermost pedicle level and be used as a first step examination for the evaluation of cervical spinal stenoses.

Vertebral pneumatocysts.

OBJECTIVE: To review the prevalence and location of vertebral pneumatocysts and evaluate the CT findings of these benign lesions. MATERIAL AND METHODS: Retrospectively we reviewed CT images of 89 patients with suspected disc disease during a 6-month period. RESULTS: Distinctive CT pattern of intraosseous pneumatocysts involving the cervical, thoracic and lumbar spine was found. In 8 patients (9%), 10 vertebral pneumatocysts were detected. Five were located in the vertebral body and 4 of these were associated with vacuum phenomenon in adjacent intervertebral discs. Five were located near the facet joint and all were associated with vacuum phenomenon in adjacent facet joint. CONCLUSION: Intraosseous pneumatocyst is a benign lesion, therefore biopsy and follow-up are unnecessary. Although vertebral pneumatocysts seem to be uncommon with a few reported cases, this study shows them to be more frequent than previously thought.

Schwachman-Diamond syndrome. A case report.

Schwachman-Diamond syndrome is an autosomal recessive disorder consisting of exocrine pancreatic insufficiency and neutropenia. The typical pathological finding with this syndrome is fatty infiltration in the pancreas of patients. We report a case of Scwachman-Diamond syndrome examined with abdominal ultrasonography, CT and radiography.

Intraosseous lipoma of the frontal bone. A case report.

Intraosseous lipomas are among the most uncommon bone tumors. They arise most often in the appendicular skeleton. There are very few reported cases of intraosseous lipomas within the skull bones. We report a case of intraosseous lipoma of the frontal bone with conventional radiography and CT findings.

Scintigraphic diagnosis of intrathoracic extramedullary hematopoiesis in a patient with beta-thalassemia.

We report the scintigraphic diagnosis of intrathoracic extramedullary hematopoiesis (EMH) in a patient with beta-thalassemia. A patient had a mass in the right thoracic paravertebral region on radiography and CT. Bone marrow imaging of the thorax by means of both Tc-99m nanocolloid and phytate demonstrated uptake of the tracer in the mediastinal mass, establishing the diagnosis of EMH.

Fascioliasis: US, CT, and MRI findings with new observations.

BACKGROUND: The purpose of this study is to describe the ultrasonographic (US), computed tomographic (CT), and magnetic resonance imaging (MRI) findings in fascioliasis and to emphasize the impact of radiology in diagnosis. METHODS: Radiologic findings in 23 consecutive patients with fascioliasis were prospectively recorded. All patients had at least one US and CT examination, and 10 of them were studied by MRI. All diagnoses were confirmed by serologic methods. In the first three cases, initial diagnosis was reached by microscopic demonstration of the parasites' eggs in bile obtained by US-guided gallbladder aspiration. RESULTS: In the hepatic phase of fascioliasis, multiple, confluent, linear, tractlike, hypodense, nonenhancing hepatic lesions were detected by CT. On US, the parasites could be clearly identified in the gallbladder or common bile duct as floating and nonshadowing echogenic particles. MRI showed the lesions as hypo- or isointense on T1-weighted images and as hyperintense on T2-weighted images. CONCLUSIONS: CT findings in the hepatic phase and US findings in the biliary phase are characteristic of fascioliasis. Because clinical and laboratory findings of fascioliasis may easily be confused with several diseases, radiologists should be familiar with the specific radiologic findings of the disease to shorten the usual long-lasting diagnostic process.

Intrapulmonary right brachiocephalic vein associated with azygos lobe.

A rare case of right brachiocephalic vein (RBV) following an extramediastinal and intrapulmonary course in the anterior portion of the azygos fissure is presented. The appearance of the RBV and superior vena cava (SVC) on the chest radiograph in patients with an azygos lobe reflects the variable relationship between these veins and their mediastinal attachments. Computed tomography (CT) can easily demonstrate the mediastinal vascular anatomy thereby allowing identification of such variants and differentiation from anomalous pulmonary veins draining into the systemic vein.

Giant cell tumor of the fourth metacarpal bone.

Giant cell tumor is among the rare tumors of the bone. We present a case of metacarpal giant cell tumor with radiographic, computed tomographic (CT) and histologic findings, as well as grey scale and Doppler sonographic features. We also present the "doughnut"-shaped appearance on scintigraphy of the lesion, which has not been shown on a metacarpal giant cell tumor.

Absence of the azygos vein.

A rare case of the absence of the azygos vein (AV) is presented. Imaging findings on plain chest film and on contrast-enhanced spiral computed tomography (CT) are described, and embryology of azygos and hemiazygos veins (HV) is reviewed. On PA chest radiographs, both the absence of AV shadow on its usual location and the presence of the aortic nipple may consider agenesis of AV, and this anomaly can be easily confirmed by CT.
