RESUMEN
BACKGROUND: Subpial hemorrhages are underrecognized, underreported, and poorly understood. The spectrum of their clinical manifestations and consequences in neonates has not been fully described. Here, we describe the demographic, clinical, and radiographic characteristics of neonates with subpial hemorrhages. METHODS: We reviewed the medical records and neuroimaging studies of neonates with subpial hemorrhage who were admitted to our neonatal intensive care unit between September 2009 and December 2020. RESULTS: Of 114 neonates with intracranial hemorrhage, 31 (27%) had subpial hemorrhage. The majority of neonates in our cohort were male (68%) and born at term (55%). The most common imaging indication was apneas and/or seizures in 58%. Common comorbid conditions included cardiorespiratory failure (42%), hypoxic-ischemic encephalopathy (26%), and coagulopathy (23%). Subpial hemorrhages were multifocal in 45% of neonates, located in the temporal lobe in 45% of neonates, and tended to be larger in neonates with coagulopathy, birth trauma, or hydrocephalus requiring neurosurgical intervention. Subpial hemorrhage was associated with another type of intracranial bleed in 77% of cases and with arterial ischemic stroke in 16% of cases. Of 17 patients with more than one year of follow-up data, 14 (82%) have developmental delay and four (24%) have epilepsy. Of 14 patients with follow-up imaging, 10 (71%) had encephalomalacia subjacent to the subpial hemorrhage. CONCLUSIONS: This is the largest cohort of neonates with subpial hemorrhages to date. Outcome data are limited by duration of follow-up and may be confounded by comorbid conditions and other concurrent hemorrhages. Further study is needed to define the spectrum of risk factors and expected neurological outcomes.

OBJECTIVE. Subpial hemorrhages, typically seen in neonates, are rare but can harm the adjacent brain parenchyma. The purpose of this review is to summarize the anatomy and pathophysiology of subpial hemorrhage and highlight its characteristic neuro-imaging pattern. CONCLUSION. The distinctive neuroimaging pattern of subpial hemorrhage is best appreciated on brain MRI, which shows the morphology over the cortex and injury to adjacent cortex and subcortical white matter. These findings do not occur in subarachnoid and subdural hemorrhages. Recognizing the pattern of subpial hemorrhages should guide prognostic precision, prognostication, and counseling.

The diagnosis of childhood absence epilepsy (CAE) is typically based on history and description of spells, supported by an office-based positive hyperventilation test and confirmed by routine electroencephalography (EEG). In the current coronavirus disease 2019 (COVID-19) pandemic, many pediatric neurologists have switched to telemedicine visits for nonemergent outpatient evaluations. We present a series of children diagnosed as having CAE on the basis of a positive hyperventilation test performed during remote televisits. Several of these children were begun on treatment for CAE prior to obtaining an EEG, with significant seizure reduction. Our series documents the feasibility of CAE diagnosis and management by telemedicine.
