5-day-old male with history of perinatal acidosis. Evaluate for parenchymal injury. Per chart, patient is an ex 37 2/7 weeks gestational age male born to a 34 year old G4P2012 mother with hypertension, superimposed pre-eclampsia, GDMA1, +HSV but no active lesions. Delivery complicated by non reassuring fetal heart tones and perinatal acidosis prompting hypothermic cooling protocol. Patient is s/p hypothermia cooling protocol and 72 hour EEG, with epileptiform discharges but no clinical or electrographic seizures. Images are limited by patient motion. There is no restricted diffusion on DWI sequences.Normal linear T1 hyperintense and T2 hypointense signal in the the posterior third of the posterior limb of the internal capsules is not optimally visualized bilaterally. The ventral lateral nuclei of the thalamus are well visualized bilaterally. There is no intraparenchymal hemorrhage or mass lesion. There is no extraaxial collection.The CSF spaces are within normal limits. There is an incidental cavum septum pellucidum et vergae. There is no mass effect or midline shift. Midline structures appear intact.There is a T2 hyperintense and T1 hypointense caput succedaneum along the central vertex, slightly greater to the right of midline, measuring up to 8 mm.
Motion limited exam. Poor visualization of normal expected signal associated with myelination in the posterior limb of the internal capsule, concerning for mild hypoxic ischemic injury as described above. Clinical correlation is recommended. No acute infarct.
