A CT scan in Wales produced an unexpected artifact:
“The Case of the Haunted Scrotum,” J.R. Harding, Journal of the Royal Society of Medicine, vol. 89. No. 10, October 1996, p. 600. (Thanks to Christine Young for bringing this to our attention.) The author, at Royal Gwent Hospital, Newport, Wales, reports: “By chance, the distribution of normal anatomical structures within the left side of the scrotum had combined to produce this image.”
