Xiphoid Process SyndromeA 59-year-old woman presented with a 30-year history of epigastric cutaneous protuberance. A mass was visible in the mid-portion of the epigastrium, particularly when in the supine position (Figure A). Sagittal computed tomography revealed an elongated and curved xiphoid process (Figure B). The measured length, width, and thickness of the xiphoid process were 63.2 mm (reference range, 40-50 mm), 21.1 mm (reference range, 15-20 mm), and 4.9 mm (reference range, 3-5 mm), respectively. The angle from the sternal body to xiphoid process was 138° (reference range, 160°-180°).
Arteriovenous Malformations in the Setting of Giant Elephantiasis NeuromatosaA 65-year-old man presented with giant elephantiasis of the left leg, accompanied by skin pigmentation and local ulceration (Figure A), which had started to grow since he was 4. Numerous café-au-lait spots were found across the trunk. The patient had previously undergone surgery 4 times during recent 10 years and had been diagnosed with neurofibromatosis type 1 (NF-1) based on clinical symptoms and histopathological results. Magnetic resonance imaging revealed extensive inhomogeneous signal intensity masses consisting of multiple flow void vascular structures.
