“…Nonetheless, the condition remains poorly understood and is still frequently unrecognized or misdiagnosed. The multiple terms used to describe external hydrocephalus, such as "pseudohydrocephalus-megalocephaly" [4], "benign subdural collections of infancy" [6], and "extraventricular obstructive hydrocephalus" [7] demonstrate the confusion that has surrounded the entity. The difficulty with diagnosing and recognizing EH is due in part to the frequency with which it is associated with other conditions, such as prematurity [9, 1 1 ], subdural hematomas [6,10], intraventricular hemorrhages [9], and genetic syndromes [2, 1 3].…”

“…Before the era of magnetic resonance (MR) imaging and Doppler ultrasound, which allow accurate identification of extracerebral fluid collections [1, 2], EH was known by a number of misnomers, including the still popular ‘benign subdural effusions of infancy’ [3, 4, 5, 6, 7, 8, 9, 10]. The prominence of the subarachnoid spaces is said generally to resolve in early childhood [9, 11, 12, 13], but the temporal course of this resolution has not been documented in detail.…”

Monozygotic Twins Discordant for External Hydrocephalus

External hydrocephalus (EH) is a transient, developmental condition in infancy characterized by macrocephaly and prominence of the subarachnoid spaces. The cause is unknown, but many patients have a family history consistent with autosomal dominant inheritance. This report describes a pair of monozygotic twins, only one of whom – the recipient of a twin-twin transfusion – has EH. Whatever the genotype of the twins, their discordant phenotypes suggest that the disproportionate calvarial growth that characterizes EH is set in motion – or not – during a limited, critical temporal window in fetal development.

“…Several studies report spontaneous resolution of the subdurals without any surgical treatment [2, 10]. It has been suggested that collections with thickness less that 7 mm on CT scan may have a better chance of resolving spontaneously, and hence non-operative approach may be sufficient [3].…”

“…While the diagnostic dilemmas have now been resolved, management of subdural collections is still a subject of controversy. Reports in the literature support 6 different modalities: conservative management (no surgery, observation alone) [2, 10], repeated subdural taps [11, 12, 13, 14, 15], burr hole drainage [13, 14], external subdural drainage [16], subdural shunting [9, 17, 18]and craniotomy with open drainage [11, 13, 19, 20]. Evaluating the literature, it is apparent that there is no clear superiority of one treatment modality over the others, although there is some bias in favour of shunting.…”

We reviewed retrospectively the management of 47 infants with subdural collections at the Birmingham Children’s Hospital. Of those patients who had needle aspiration as their initial treatment 42% required some form of further treatment and 25% were complicated by infection of the subdural collection. Of those patients treated with burr hole evacuation or with observation alone, 78 and 73%, respectively, required no further procedures. However, 17% of those who had burr holes as their initial treatment developed post-operative infected collections. Of those who had subdural-peritoneal shunt as initial or subsequent treatment, none required further procedures to treat the subdural collections. No infections were noted following shunting. There was no statistically significant difference in overall clinical outcome at last follow-up between the different treatment groups. We conclude that needle aspirations should be avoided due to high infection risk, and that observation alone can be sufficient in the absence of intracranial hypertension, as the condition may be self-limiting. In cases requiring surgery, it should be borne in mind that burr hole evacuation has a higher infection risk, whereas subdural shunting has the additional need for removal of the device if the parents and surgeon decide accordingly.
