Occasionally, these manifestations may be rare and atypical, challenging the clinician\u2019s ability to recognize the disease. The description of the clinical characteristics and neuroradiological remarks of patients with specific mutations may improve clinicians\u2019 ability to identify them.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>We report the case of a woman who presented with early\u2010onset, rapidly progressive dementia associated with bilateral hyperintensity of the medial temporal lobe on T2\u2010weighted MRI. After more common etiologies were excluded, genetic testing revealed a PSEN\u20101 C779T mutation. Notably, her brother, who carried the same mutation, did not exhibit these atypical neuroradiological findings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This case underscores the phenotypic variability associated with PSEN\u20101 mutations, even among individuals within the same family. Such variability and the possibility of atypical presentations may complicate the diagnostic process. In the presence of early\u2010onset and rapidly progressive dementia associated with bilateral hyperintensity of the medial temporal lobe, ADAD and PSEN\u20101 mutation may be suspected and need to be addressed.<\/jats:p>\n
