ABSTRACT
BACKGROUND: A 26-year-old male presented with pain in his left tibia. Ultrasonography revealed no abnormalities. Tc-99m-bonescan was requested to rule out stress fracture. The scan confirmed the presence of a left tibial stress fracture, as well as an enhancing lesion in the left parietal bone. The patient had no neurological symptoms.
ABSTRACT
We describe two infants in whom MRI diagnosed osteomyelitis of the cuboid bone when conventional X-rays were negative. Neoplastic, traumatic and ischaemic aetiologies could be excluded with the initial MR examinations.

We report a case of aortic coarctation associated with an aberrant right subclavian artery in a young male who was investigated for hypertension. Angiography, CT examination with multiplanar reconstruction and MRI were useful in delineating the extension of the coarctation and the exact anatomy of the aberrant right subclavian artery.

OBJECTIVE: To describe the contrast enhancement pattern of orbital cavernous hemangioma on sequential Gd-enhanced MRI. MATERIALS AND METHODS: Six patients with an orbital mass lesion were examined with T1- and T2-weighted spin echo MRI. After intravenous administration of Gd-chelate at a dose of 0.1 mmol/kg, T1-weighted spin echo sequences were performed immediately after, after 15 to 30 min, and up to 1 h after the injection. In two patients a fat saturation prepulse was given before the Gd-enhanced study. RESULTS: In all patients the lesions were isointense to muscle on the T1-weighted sequence and hyperintense to muscle on the T2-weighted sequences. After gadolinium, all lesions showed initial central patchy enhancement. Between 20 and 60 min after the injection the lesions showed total and homogeneous filling up. CONCLUSIONS: Progressive and total homogeneous filling up of an orbital mass of Gd-enhanced MRI is a pathognomonic sign of cavernous hemangioma.
