ABSTRACT.Purpose: The aim of this prospective study was to assess the ocular hemodynamic changes in patients with Behçet's disease who had involvement of the posterior segment by color Doppler ultrasonography. Methods: The present study was carried out in 32 eyes of 24 patients with ocular Behçet's disease and 42 eyes of 21 persons as a healthy age-matched control group. In order to detect the hemodynamic changes in ocular Behçet's disease, peak systolic and end-diastolic velocities (PSV, EDV; cm/sec), resistive and pulsatile indices (RI, PI), and PSV/EDV ratio of central retinal artery (CRA), short posterior ciliary artery (PCA) and ophthalmic artery (OA) were determined. Results: The mean PSV and EDV (8.1∫2.6 and 2.7∫0.1 cm/sec, respectively) in the CRA were significantly lower in patients with Behçet's disease than in healthy controls (11.5∫2.2 and 3.5∫1.0 cm/sec, respectively, p∞0.001). For the PCA, these values (12.7∫4.2 and 4.3∫1.1 cm/sec, respectively) were significantly lower in the patient group than in the control the group (18.2∫4.2 and 6.1∫2.5 cm/sec, respectively, p∞0.001). In the patient group, a statistically significant decrease compared to the control group was detected in the mean PSV of the OA (31.8∫8.2 and 35.8∫0.6 cm/sec, respectively, p∞0.02). However, no significant difference in the other parameters of these vessels was observed between groups.Conclusions: These results demonstrate the presence of some circulatory changes in the flow velocities of the CRA, PCA and OA in patients with Behçet's disease when compared with control subjects.

A 57-year-old male patient presented with an immobile ellipsoid mass of 6-cm diameter in the right occipitoparietal region. Cranial computed tomography showed the mass with dense contrast enhancement causing bone destruction. After embolization of the mass, total resection was performed. Histological examination showed the mass had a capsule, with no invasion of the dura mater or dermis, and the follicles of various sizes covered with mono-lined thyrocytes were full of colloid. Immunohistochemical examination showed positive staining for thyroglobulin. Postoperatively, levels of thyroid hormones were normal, and thyroid ultrasonography and technetium-99m scintigraphy showed no abnormalities. Fine needle aspiration biopsy performed at various locations of the thyroid gland revealed no atypical thyroid cells. Whole body technetium-99m scintigraphy found no abnormal bone involvement. The histological evidence was suggestive of follicular carcinoma metastasis. Surgical treatment was planned for the thyroid gland, but the patient did not consent. Two years later, the patient presented with the pain and sensitivity in the sacrum, the right iliac wing, and the right caput femoris. Computed tomography revealed lytic lesions in these areas. Bone metastases were identified. Whole body scintigraphy showed increased activity in these regions, but the cranium and all other tissues were normal. The patient underwent total thyroidectomy under a diagnosis of follicular carcinoma. The present case of a lytic skull lesion associated with normal thyroid tissue on admission but finally treated as follicular thyroid cancer emphasizes the difficulty in histological discrimination of follicular carcinoma from normal thyroid tissue.

We report CT and MRI findings in two patients with ameloblastoma. One case had a multilocular mixed lesion and the other had a unilocular solid pattern. The second case is probably one of the youngest reported. CT and MRI can be used to delineate and show the extent of the tumour.
