"Aunt Minnie" is a common term in radiology which refers to radiologic finding with no differential diagnoses. Drawing attention to those diseases for which no practical diagnosis exists, this text presents difficult cases frequently encountered, and offers pertinent teaching points and references. The material is organized into 10 specialties for the board examination: paediatrics; muscoloskeletal; cardiovascular and interventional; ultrasound; nuclear medicine; neuroradiology; thoracic imaging; mammography; gastroenterology; and genitourinary. The information is presented in case formats, and "Aunt Minnie's Pearls" are given at the end of each case. Residents preparing for oral board examinations should find this book useful, since these diseases often demonstrate imaging findings which are perplexing to all but the highly experienced.
