Background:
Delayed subaponeurotic fluid collection (DSFC) is a relatively uncommon problem, probably under reported soft swelling in the scalp which usually develops in infancy that occurs weeks to months after birth. Although the exact etiology remains unclear, several theories have been postulated such as (i) cerebrospinal fluids (CSF) leak from microfractures of the skull and (ii) disrupted lymphatic drainage, gradually liquefying subaponeurotic bleeding. Here, we reported typical clinical findings of DSFC and analysis of the fluid aspirate from our patient. To the best of our knowledge, this is the first case reported from Asia, particularly from Indonesia.
Case description:
A healthy 2-month-old girl infant presented with 2 weeks history of occipital painless fluctuant scalp mass with no swelling. She was born at term from a nulliparous mother; by emergency cesarean delivery following failed induction of labor. There was no history of scalp injury at birth nor recent head trauma; ultrasonography showed translucent fluid in subaponeurotic or subgaleal space. The fluid collection was noted to be fluctuant, free-flowing across suture lines, without discoloration or bruising; when placed supine, the fluid collected at her midocciput. A diagnostic tap confirmed the presence of serosanguinous CSF led to a diagnosis of DSFC.
Conclusion:
Herein, we reported the first DSFC case from Indonesia. With no previous experience of the condition, a definitive diagnosis was possible through a very carefully physical examination and history taking, along with a good communication among the neurosurgeon, pediatrician, and the clinical pathologist.
