Unknown Case Part 1 Paul Harkey, MD and Douglas Robertson, MD PARTI A 23-year-old Caucasian female presented to her dermatologist after noticing a growing clear bluish lesion on her right forearm. A shave biopsy was performed that demonstrated malignant melanoma with positive peripheral margins, and
she subsequently underwent local wide excision with sentinel lymph node biopsy. An initial whole-body examination by positron emission tomography-computed tomography was performed, followed by dedicated cervical spine magnetic resonance imaging and computed tomography.
Figure 1. Axial PET-CT (A) and sagittal noncontrast enhanced CT scans of the cervical spine demonstrate a hypermetabolic lytic lesion in the C7 vertebral body (white arrow). C7 lytic mildly expansile lesion approximates the posterior cortex with severe cortical thinning (B). PET-CT indicates positron emission tomography-computed tomography.
Figure 2. T l - and T2-weighted (A, B) and T 1 weighted fat saturated postcontrast (C) sagittal images of the cervical spine demonstrating a solitary C7 vertebral body lesion. The wellcircumscribed C7 lesion is hypointense to adjacent normal cancellous bone on Tl Wl (A) and heterogeneously hyperintense on T2 Wl (B) and demonstrates avid postcontrast enhancement (C). Notice a lack of peripheral edema or epidural component. From the Department of Radiology and Imaging Sciences, Emory University, Atlanta, GA. Acknowledgment date: October 17, 2013. Revision date: November 18, 2013. Acceptance date: November 22, 2013. The manuscript submitted does not contain information about medical device(s)/drug(s).
