  ABSTRACT: The case of a 64-year-old male patient who presented with a bulky osseous tumor metastasis from renal cell carcinoma is reported. The metastatic lesion extended from the acetabulum of the left iliac bone into the iliosacral joint.Treatment plan included selective arterial embolization followed by transdermal radiofrequency ablation, followed by consolidation irradiation. This sequence resulted in considerable necrosis of the bulk of the tumor and creation of a large tissue deficit, which healed over the period of several months despite anti-angiogenetic systematic treatment. The patient remains in good state of health, 20 months after the procedure. This case illustrates the usefulness of the embolization-ablation sequence in controlling large osseus metastasis.

  ABSTRACT: A persistent PHA is the second most common of the embryonic carotid-basilar anastomoses that fail to regress in the embryo. The fact that PHA often is functionally a single artery providing blood to the posterior circulation poses challenging therapeutic problems in case of an aneurysm located on the PHA. A 46-year-old woman presented with SAH due to a large ruptured aneurysm of the left PHA. Identification of such an artery by CT angiogram is the proposed cold standard. The aneurysm was obliterated by coil embolization. To our knowledge, this is the first reported case of aneurysm located on a primitive persistent hypoglossal artery that was endovascularly treated. Aneurysms located on a persistent PHA can be treated safely and effectively via an endovascular approach.

  ABSTRACT: To compare (99m)Tc-depreotide and (201)Tl chloride SPET in the characterization of pulmonary lesions. Fifty-seven pulmonary lesions from 33 patients suspected of malignancy in computed tomography, were assessed by (99m)Tc-depreotide and (201)Tl early and delayed SPET imaging. Images were visually assessed and the tumour-to-normal (T/N) lung activity ratio for early (ER) and delayed (DR) scans and the retention index (RI), were calculated in every lesion. A final diagnosis was reached for all lesions, based either on histology or prolonged clinical and radiological follow-up. Twenty-three lesions were characterized as malignant and 34 benign. In visual analysis, all malignant lesions accumulated both tracers resulting in sensitivity and negative predictive values of 100%. However, false positive interpretations resulted in a specificity of 64.7% and 67.6% for (99m)Tc-depreotide and (201)Tl, respectively. ER and DR of both agents and the RI of (99m)Tc-depreotide were significantly higher in malignant, compared to benign lesions. In defining thresholds of abnormality from ROC analysis, a significant increase in specificity was observed for both tracers in both scan phases (91.2% for all), as compared to visual analysis (P<0.01). There was no significant difference in the diagnostic performance between (99m)Tc-depreotide DR and (201)Tl DR, although the former provided the highest T/N ratio. This study demonstrates that (99m)Tc-depreotide and (201)Tl SPET are equally effective and may be useful in the non-invasive determination of lung malignancy. The specificity of both techniques is significantly improved by quantifying radiopharmaceutical accumulation in pulmonary lesions.

  ABSTRACT: Aggressive angiomyxoma is a rare soft-tissue neoplasm found mainly in the female pelvis. Approximately 130 cases have been reported in the literature to date. In most cases treatment consists of surgical resection, but local recurrence rates remain high (36-72%). Therefore, long-term follow up is necessary and magnetic resonance imaging seems to be the preferred method for detecting recurrence. We report our experience of a primary and a recurrent aggressive angiomyxoma.

  ABSTRACT: Epidural abscess is an uncommon infectious disease. Cervical spine is the least frequent site of spinal epidural abscess (SEA). We presented a rare case of cervical epidural abscess in a 70-year-old patient with no predisposing condition secondary to soft tissue abscess formation. The clinical presentation included fever; neck pain and symptoms of spinal cord compression. Leukocyte count and erythrocyte sedimentation rates were elevated. Computed tomography (CT) showed air within the spinal canal. Magnetic resonance imaging (MRI) showed an epidural mass at C2–C7 with low signal intensity on T1 weighted, high signal intensity on T2 weighted and ring-like enhancement with gadolinium. The lesion communicated through a narrow neck with an extra spinal postvertebral mass. Diagnosis was confirmed during operation. Laminectomy was performed and an encapsulated abscess with epidural and extra spinal component containing yellowish pus was totally removed. Staphylococcus aureus was detected in a culture of the epidural pus. MRI is the study of choice in the evaluation of infectious diseases of the spinal cord and spinal column since it allows direct visualization of paraspinal musculature.
