Memory flashbacks are usually attributed to recreational drugs or psychiatric conditions. The differential diagnosis for memory flashbacks is diverse and challenging; moreover, management is influenced by the working diagnosis. We describe the case of a 35-year-old man who presented with memory flashbacks secondary to temporal lobe seizures from an unruptured aneurysm of the posterior cerebral artery. To our knowledge, a case of this nature has not been previously reported. This case demonstrates the need to recognize that, on rare occasions, a complaint of memory flashbacks can be the result of an organic etiology. We also discuss the challenging presentations of temporal lobe seizures, as they can easily be misdiagnosed as a psychiatric condition.
