This issue examines molecular imaging and conditions that can complicate neurological diagnosis. Four contributions address tumor-induced osteomalacia, a thoracic spinal hemangioma presenting with features of cauda equina syndrome, LGI1 autoimmune encephalitis mimicking stroke, and FDG PET/CT in prosthetic valve endocarditis. Together, they illustrate the need to relate imaging patterns to the clinical presentation when considering uncommon explanations for familiar symptoms. The authors are affiliated with institutions in Argentina, Morocco and the United States.
