A 20-year-old woman with secondary amenorrhoea and an empty sella turcica was found to have a cyst of the cavum septi pellucidi (CSP) on MRI. The cyst had regressed spontaneously on follow-up MRI.

PURPOSE: To describe findings at radiologic evaluation of pulmonary arterial involvement in Behçet disease. MATERIALS AND METHODS: Between 1978 and 1993, 31 pulmonary arterial aneurysms were diagnosed in 15 consecutive male patients, aged 21-56 years (mean, 32 years 5 months), with known Behçet disease. The patients were assessed at chest radiography (n = 15), computed tomography (n = 14), angiography (n = 10), and magnetic resonance (MR) imaging (n = 2). RESULTS: Three patients had single and 12 had multiple pulmonary aneurysms. In six patients, aneurysms were associated with pulmonary artery occlusion. Follow-up chest radiography revealed five subjects with progression leading to fatal rupture of aneurysms and two subjects with regression of the aneurysms and cessation of their symptoms. CONCLUSION: Intravenous digital subtraction angiography was the procedure of choice in the documentation of pulmonary arterial involvement, and MR imaging was most helpful in the presumptive diagnosis of occluded aneurysms. The appearance of pulmonary aneurysms represents a poor prognosis in patients with Behçet disease, but there is a chance that the aneurysms will not rupture.
A case of aberrant anterior cerebral artery origin of the ophthalmic artery is presented. This indubitable radiological demonstration of such variation highlights some hypothetic steps in the embryogenesis of the ophthalmic artery.
Hydatid disease (HD) of the cervical spine is rare. A case investigated by computed tomography (CT) and magnetic resonance imaging (MRI) is presented. While CT shows the bone lesion better, MRI is superior in demonstrating compression of neural structures. The complementary use of CT and MRI in such cases is suggested.
Two cases of unilateral proptosis due to orbital hydatid disease are reported. In both cases CT scans showed well-defined, thin-walled cystic masses whose densitometric values were similar to that of the globe.
In 1958 Caroli described the syndrome of congenital, either segmental or involving the entire bile duct system, saccular extensions of the intrahepatic bile ducts. He differentiated between two types of this disease pattern. The first form concerns pure cystic dilatations of the intrahepatic bile ducts, whereas the second one is combined with hepatic fibrosis and portal hypertension. Both types are characterised by cystic dilatations in the kidneys and in the extrahepatic bile ducts, pancreas and spleen.

Renal hemangiomas are rare neoplasms of the kidney, and the number of cases reported in the literature are about 200 since the original description by Virchow in 1867. Among these, only a few have been examined by the combination of ultrasound, computed tomography, and angiography. We present a demonstrative case diagnosed at our clinic and review the corresponding literature.
