“…In this case report, by using DTT, we were able to detect injuries of the STT, CST, CRT, and fornix in a patient with whiplash injury, and the neural injuries were consistent with the clinical features of this patient; that is, central pain (injury of the STT), quadriparesis (injury of the CST and CRT), and memory impairment (injury of the fornix) [10][11][12][13][14][15][16][17][18]. Because no definite brain lesion was observed on conventional brain MRI, TAI appeared to be the most likely pathogenetic mechanism for injuries of these neural tracts [18,23].…”

“…Recently, with the introduction of diffusion tensor imaging (DTI), several studies have used diffusion tensor tractography (DTT), which is derived from DTI data, to demonstrate traumatic axonal injury (TAI). In patients with whiplash injury, TAI is the tearing of axons, due to indirect shearing forces during acceleration, deceleration, and rotation of the brain [10][11][12][13][14][15][16][17][18].…”

Objectives: We report on a patient with whiplash injury who had central pain, due to injury of the spinothalamic tract (STT), but who was misdiagnosed as complex regional pain syndrome (CRPS). Case description: While a minivan in which a 43-year-old female was seated in the passenger seat was stopped for a signal, a truck collided with the minivan from behind, and the minivan then repeatedly collided with trucks in front and behind the minivan. Her head repeatedly struck the minivan seat resulting in whiplash injuries. After onset, she felt pain in both legs with mild motor weakness in all four extremities and memory impairment. Eight years after onset, she was diagnosed at a university hospital as CRPS type 1 with the clinical features of hyperalgesia and mild edema and motor weakness of both legs. She visited another university hospital nine years after onset and complained of pain in the right arm and both legs, constant tingling and burning pain along with allodynia and hyperalgesia. She also showed mild weakness in the four extremities, mild edema of both legs, and memory impairment. On diffusion tensor tractography (DTT), the left spinothalamic tract (STT) showed marked narrowing, and the right STT revealed mild narrowing and partial tearing. In addition, partial tears were observed in both corticospinal tracts and the right corticoreticulospinal tract. Discontinuations were observed in the left corticoreticulospinal tract and the left fornical crus. Conclusion: Injury of the STT was demonstrated on DTT in a patient with central pain following whiplash injury. Previously, the patient was misdiagnosed as CRPS.

“…10Y12 In 2013, Yeo et al 10 reported on discontinuation of the CRP at the midbrain level in a patient with a contusional hemorrhage in the right frontotemporal lobes who showed proximal weakness. In 2014, Kwon and Jang 11 reported on a patient who showed gait disturbance and quadriparesis with more severe weakness of the proximal joints due to injury of both CRPs following mild TBI. Lee et al (2015) recently demonstrated injury of the CRP in 29 patients with proximal weakness after mild TBI.…”

“…After the introduction of diffusion tensor imaging (DTI), many studies using diffusion tensor tractography (DTT), which is reconstructed from DTI data, have demonstrated neural injuries of various neural tracts in patients with cerebral concussion or mild traumatic brain injury (TBI) who showed no abnormal lesion on conventional brain MRI [11][12][13][14][15]. Among these studies, several studies have reported injury of neural tracts and their relavant clinical symptoms following whiplash injury [16][17][18][19]. These neural tracts comprise the corticospinal tract, the corticoreticulospinal tract, the dentatorubrothalamic tract, the ascending reticular activating system, and the spinothalamic tract [16][17][18][19].…”

We report on a patient with tinnitus who showed injury of auditory radiation following whiplash injury, demonstrated by diffusion tensor tractography (DTT). A 48-year-old male patient suffered from a car crash resulting in flexion-hyperextension injury of his head after being hit from behind by a moving car while waiting at a signal while driving a car. Three days after the car crash, he began to feel tinnitus in both ears and his tinnitus became aggravated with the passage of time. No specific lesion was observed on a conventional brain MRI performed two weeks after the car crash. Although he visited several hospitals, the precise cause of his tinnitus was not detected. Two years after the car crash, he underwent evaluation for his tinnitus at the ear, nose and throat department of a university hospital. The pure tone audiometry was evaluated in a sound-proof room to screen his hearing status for the frequencies of 250–8000 Hz and no specific abnormality was detected. Although he was also tested for speech audiometry, there was also no specific abnormality. In order to assess his tinnitus, a tinnitogram was conducted to evaluate the frequency content and the loudness. His tinnitus was characterized at an intensity of 40 dB and a frequency of 4000 Hz. However, no abnormality was observed in either ear on physical examination. On DTT, the auditory radiation showed severe narrowing and tearing in both hemispheres. To summarize, neural injury of the auditory radiation was demonstrated in a patient with tinnitus following whiplash injury, using DTT.
