Abstract:Background: Delayed subaponeurotic fluid collection (DSFC) is a self-limited disorder of unknown etiology characterized by a benign, fluid-filled mass in the subaponeurotic layer of an infant's scalp. While a few case series describe DSFC, the experiences of families whose infants develop this condition have not previously been reported.Methods: We used a disease-specific blog to evaluate the experiences of 69 families affected by DSFC. We identified self-reported clinical features of DSFC and qualitatively an… Show more
“…Some of the themes that emerged from the research included lack of provider awareness, concern about unnecessary diagnostic procedures, and parental anxiety regarding accusations of child abuse. 15 Hopefully, as increased physician awareness regarding this rare entity emerges, there will be improved understanding of the benign and self-resolving nature of SSFC, and a reduction in unnecessary diagnostic testing, child abuse investigations, inpatient admissions, and interventions.…”
OBJECTIVESpontaneous subaponeurotic fluid collection (SSFC) is an uncommon and newly described entity of unknown etiology, observed in infants less than 1 year of age. The authors report on series of infants who presented to the Hospital for Sick Children (HSC) with SSFC, focusing on the natural history of this condition.METHODSData from the Hospital for Sick Children were retrospectively reviewed for the period between January 2004 and June 2015. Patient age and sex, birth history, medical history, laboratory findings, and symptoms were reviewed. SSFC location, imaging characteristics, management, and outcome were also analyzed. A MEDLINE and Embase literature search was performed on the condition, yielding previously reported cases of SSFC in the English language.RESULTSNine cases involving patients who presented with SSFC during the study period were identified. The patients were 4 male and 5 female infants (age range 5 weeks to 11 months). All cases of SSFC developed spontaneously over a period of days, and the infants had no history of injuries, trauma, or hair manipulation in the immediate period preceding the development of the subgaleal collections. Six patients underwent remote forceps- or vacuum-assisted instrumented births, although none of the patients developed scalp collections or skin discoloration immediately after birth. All of the cases were managed conservatively on an outpatient (6 cases) or inpatient (3 cases) basis. In 1 case, the size of the fluid collection fluctuated over 4 months, but in all of the cases, the collections resolved spontaneously without structural or infectious complications.CONCLUSIONSThis is the largest series describing SSFC to date and summarizes 9 cases managed at a large academic neurosurgical center. Although the specific pathophysiology of SSFC remains unknown, in some cases the condition may be associated with a remote history of instrumented delivery. SSFC occurs spontaneously without immediate preceding trauma, and an extensive hematology or child abuse workup is not necessary. A conservative approach with outpatient follow-up is advocated.

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Since its rarity and limited cases reported around the world, many physicians never seen DSFCs before and may not recognize its clinical entity in the first place; Worthen et al published article concerning rare scalp mass that identified through a disease-specific blog, analyzing experiences of 69 families whose infants developed DSFCs. [17] Hopkins et al reported the first six cases of DSFCs that managed conservatively and one case was managed by a needle aspiration of the collection on two occasions when serosanguinous fluid was aspirated ×2 after diagnosis. [3] Schoberer et al [11] and Munjal and Kumar [8] reported one case managed by 2 times aspiration, since they observed the reaccumulation of the fluid.…”
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.
“…Seventy-five percent of infants were evaluated in a primary care setting and 38% in the ED. 1 All participants reported that providers were unaware of the clinical features of SFC, which led to imaging in 100% of cases and included exposure to radiation (53% cases), repeated evaluation, and in some cases referral to specialists and/or suspicion of child abuse (9 cases). 1 Many responders felt medical evaluation increased rather than relieved their concerns.…”
A 29-day-old infant presented to the emergency department (ED) with increasing painless scalp swelling. The swelling was first noted 2 weeks ago. Since that time, it has doubled in size. The family denied a history of trauma.She was born at term by cesarean delivery for failure to descend with fetal distress. Neither vacuum nor forceps were used. A fetal scalp electrode was placed during labor. After delivery, intramuscular vitamin K was administered. Her newborn course was complicated by hypoglycemia attributed to poor feeding. Scalp swelling was not present at birth or during the newborn hospitalization. There were no issues with jaundice and her newborn metabolic screen was normal.Since discharge, she has been exclusively fed breast milk and has been growing well, with documented weight gain of 30 g per day.
