Point-of-care ultrasound in the diagnosis of neonatal cerebral sinovenous thrombosis.

Cerebral sinovenous thrombosis (CSVT) mostly affects sick neonates in the neonatal intensive care unit (NICU) with predisposing or underlying conditions. The clinical presentation is nonspecific which often leads to a delayed or missed diagnosis. Point-of-care ultrasound (POCUS) use in the NICU is rapidly increasing. One of the main uses of neonatologist-performed POCUS is cranial ultrasound which permits diagnosis and monitoring of neurological disease at the bedside. We present the case of a neonate with a complex clinical situation where cranial POCUS permitted a prompt diagnosis and treatment of severe CSVT by imaging the transverse sinuses through the mastoid fontanelle.
