ObjectivesWe reported on a patient with mild traumatic brain injury (TBI) who showed recovery of an injured cingulum concurrent with improvement of short-term memory, which was demonstrated on follow-up diffusion tensor tractography (DTT).MethodsA 55-year-old male patient suffered head trauma resulting from falling from approximately 2 m while working at a construction site. The patient showed mild memory impairment (especially short-term memory impairment) at 3 months after onset: Memory Assessment Scale (global memory: 95 (37%ile), short-term memory: 75 (5%ile), verbal memory: 80 (9%ile) and visual memory: 112 (79%ile)). By contrast, at 2 years after onset, his mild memory impairment had improved to a normal state: Memory Assessment Scale (global memory: 104 (61%ile), short-term memory: 95 (37%ile), verbal memory: 101 (53%ile) and visual memory: 106 (66%ile)).ResultsOn 3-month DTT, discontinuation of the right anterior cingulum was observed over the genu of the corpus callosum, while on 2-year DTT, the discontinued right anterior cingulum was elongated to the right basal forebrain.ConclusionIn conclusion, recovery of an injured cingulum concurrent with improvement of short-term memory was demonstrated in a patient with mild TBI.
