"Benign enlargement of the subarachnoid spaces in infancy is a self-limiting condition. Enlargement of the subarachnoid spaces typically resolves spontaneously by 2–3 years of age, although macrocephaly may persist despite radiological resolution of the cerebrospinal fluid collections 3."
"Benign enlargement of the subarachnoid spaces in infancy (BESS or BESSI), also known as benign external hydrocephalus (BEH), is a benign enlargement of the subarachnoid spaces in infants. It usually involves the frontal lobe subarachnoid spaces, and it is characterised clinically by macrocephaly or frontal bossing."

"another key distinction between benign enlargement of the subarachnoid spaces and a subdural fluid collection is that in the former the cortical veins will be seen coursing up to the inner table of the calvaria on MRI and ultrasound; whereas in the latter the veins are displaced away from the inner table, as the arachnoid membrane and subarachnoid space are displaced (see cortical vein sign)"
"Infants have an increased susceptibility to subdural haemorrhage, which may occur spontaneously or following minor head trauma. The presence of a subdural haematoma in an infant with benign enlargement of the subarachnoid spaces should not, in isolation, be regarded as diagnostic of abusive head trauma; rather, it should be interpreted in conjunction with the clinical history, physical examination, ophthalmologic findings, and other neuroimaging features 4."
