Evaluation of the PECARN rule for traumatic brain injury applied to infants younger than 3 months and creation of a modified, age-specific rule. Eur J Pediatr 2023; 182:191-200. [PMID: 36278996 DOI: 10.1007/s00431-022-04661-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 10/11/2022] [Accepted: 10/12/2022] [Indexed: 01/12/2023]
Abstract
UNLABELLED Infants < 3 months with minor head trauma (MHT) are a particularly vulnerable group, though few studies have focused specifically on these patients. We aimed to evaluate the application of the PECARN prediction rule, designed for clinically important traumatic brain injury (ciTBI) in children < 2 years in infants < 3 months, and create a specific prediction rule for this population. We conducted a prospective multicenter observational study in 13 pediatric emergency departments (PEDs) in Spain. The PECARN rule was applied to all patients. A new specific prediction rule for infants < 3 months of age was created. The main outcome measures were (1) ciTBI, (2) TBI evidenced on computed tomography (CT) scan, and (3) isolated skull fracture (ISF). Telephone follow-up was conducted for all patients over the 4 weeks after the initial PED visit. Of 21,981 children with MHT, 366 (1.7%) were < 3 months old and 195 (53.3%) underwent neuroimaging, including 37 (10.1%) with CT scan. The sensitivity and negative predictive value (NPV) of the PECARN prediction rule for ciTBI were 100% (95% CI, 20.7-100) and 99.7% (95% CI, 98.4-100%), respectively. Of the 230 infants (62.8%) who met the PECARN low-risk criteria, none had ciTBI, 1 (0.4% overall, 95% CI, 0-2.4) had TBI on CT, and 2 (0.9% overall; 95% CI, 0.1-3.1) had an ISF. Among the 136 infants (37.2%) who did not meet the PECARN low-risk criteria, 1 (0.3% overall; 95% CI, 0-1.5) had ciTBI, 11 (8.1% overall; 95% CI, 4.1-14.0) had TBI on CT, and 18 (13.2% overall; 95% CI, 8-20.1) had an ISF. The sensitivity and NPV of the Spanish prediction rule for ciTBI were 100% (95% CI, 20.7-100) and 100% (95% CI, 98.4-100%), respectively. No infants in the registry developed complications during follow-up. CONCLUSION The PECARN rule for infants < 2 years old accurately identified infants < 3 months old at low risk for ciTBI in our population, although the adapted Spanish rule presented here could be even more accurate. WHAT IS KNOWN • Infants younger than 3 months are vulnerable to minor blunt head trauma due to their age and to difficulties in assessing the subtle symptoms and minimal physical findings detected on examination. • A low threshold for CT scan is recommended in this population. WHAT IS NEW • PECARN rule for infants < 2 years old is an adequate tool with which to identify infants < 3 months old at low risk for clinically important traumatic brain injury. • Spanish rule could identify even more low-risk infants without overlooking important outcomes but it should be validated to confirm its predictive capacity.

Abstract
Traumatic brain injury (TBI) is a major public health issue that causes significant morbidity and mortality in the pediatric population. Pediatric minor TBIs are the most common and are widely underreported because not all patients seek medical attention. The specific management of these patients is distinct from that of adult patients because of the different physiologies in these age groups. This article focuses on minor TBIs, particularly growing skull fractures, traumatic cerebrospinal fluid leakage, and concussion.

Abstract
BACKGROUND Herniation of the brain through an osseodural defect has been well described in small children as an uncommon occurrence after closed head injury. Pressure from the growing brain has been implicated in progressive enlargement and reshaping of the fracture line. An analogous phenomenon in adults has been observed in the described cases where neurosurgical intervention led to a persistent dural defect. Transcalvarial herniation of the brain through the dural defect resulted in characteristic neurologic and imaging findings producing symptoms disproportionately greater than expected from the extent of the affected brain, accompanied by enlargement of the underlying ventricle and elevation of the bone flap. Disruption of the axonal conduction due to distortion of the axons in the herniated brain is probably responsible for these observations. CASE DESCRIPTION A series of 3 cases is described. In all cases, the dural reconstitution at the conclusion of surgery was incomplete. Brain herniation was evident in the postoperative scan. The transcalvarial herniation of the brain was precipitated by either a seizure and resultant brain swelling or persistently raised intracranial tension from a tumor residual. In 2 cases, surgical reexploration resulted in improvement in the neurologic symptoms. CONCLUSIONS In symptomatic patients with transcalvarial herniation of the brain, identified on imaging, the neurologic syndrome is quite characteristic. Recognition of this condition and prompt treatment lead to lasting neurologic improvement.

Abstract
BACKGROUND Growing skull fracture (GSF) is a rare complication of pediatric head trauma and causes delayed onset neurological deficits and cranial defect. GSF usually develops following linear fracture with underlying dural tear resulting in herniation of the brain. Early diagnosis and treatment are essential to avoid complications. However, there are no clear-cut guidelines for the early diagnosis of GSF. The present study was conducted to identify the criteria for the early diagnosis of GSF. MATERIAL AND METHODS From 2010 to 2015, all pediatric patients of head trauma with linear fracture were evaluated. Patients of age <5 years with cephalhematoma, bone diastasis of 4 mm or more with underlying brain contusion were subjected to contrast brain MRI to find out the dural tear and herniation of the brain matter. Patients with contrast MRI showing dural tear and herniation of the brain matter were considered high risk for the development of GSF and treated surgically within 1 month of trauma. Patients with contrast brain MRI not showing dural tear and herniation of the brain matter were regularly followed for any signs of GSF. RESULTS A total of 20 patients were evaluated, out of which 16 showed dural defects with herniation of the brain matter and were subjected to duraplasty. Four patients in which MRI did not show dural tear and herniation of the brain matter were regularly followed-up and have not shown any sign of GSF later on follow-up. CONCLUSION Early diagnosis of GSF can be made based on the four criteria, i.e., (1) age <5 year with cephalhematoma, (2) bone diastasis 4 mm or more (3) underlying brain contusion (4) contrast MRI showing dural tear and herniation of the brain matter. Dural tear with herniation of the brain matter is the main etiopathogenic factor for the development of GSF. Early diagnosis and treatment of GSF can yield a good outcome.

Abstract
OBJECT A growing skull fracture (GSF) is a rare but significant late complication of skull fractures, usually occurring during infancy and early childhood. Delayed diagnosis and improper treatment could exacerbate this disease. The aim of this study was to introduce a new hypothesis about, describe the stages of, and discuss the treatment strategy for GSF. METHODS The authors performed a retrospective review of 27 patients with GSF, who were grouped according to 3 different GSF stages. RESULTS Over a period of 20 years, 27 patients with GSF (16 males and 11 females) were treated in the authors' department. The mean follow-up period was 26.5 months. Six patients were in the prephase of GSF (Stage 1), 10 patients in the early phase (Stage 2), and 11 in the late phase (Stage 3). All patients underwent duraplasty. All 6 patients at Stage 1 and 5 patients at Stage 2 underwent craniotomy without cranioplasty. Five patients at Stage 2 and all of the patients at Stage 3 underwent cranioplasty with autologous bone and alloplastic materials, respectively. Among all patients, 5 underwent ventriculoperitoneal shunt placement. Symptoms in all patients at Stages 1 and 2 were alleviated or disappeared, and the cranial bones developed without deformity during follow-up. Among patients with Stage 3 GSF, no obvious improvement in neurological deficits was observed. Three patients underwent additional operations because of cranial deformation or infection. CONCLUSIONS The authors identify the stages of GSF according to a new hypothesis. They conclude that accurately diagnosing and treating GSF during Stages 1 and 2 leads to a better prognosis.

Abstract
The author describes 2 cases of children with growing skull fractures (GSFs). Surgical exploration of the widened fracture shortly after the head injury failed to reveal a dural tear because the neuroimaging studies (MR images, CT scans, and skull radiographs) had not been accurately interpreted, thereby allowing the development of a GSF at the site of the actual dural injury. In both cases, the dural and bony defect and the leptomeningeal cyst were successfully repaired. To prevent GSFs associated with progressive neurological deficit, seizure, ventricular porencephaly, and encephalomalacia, the author surgically explores wide skull fractures in young children with head injury whose MR images demonstrate brain herniation through the dura mater. The importance of a brief delay in surgical exploration is emphasized to allow cerebral edema to resolve and the patient's condition to become medically stabilized.

Abstract
OBJECTIVE To present the case of a leptomeningeal cyst involving the orbital roof in an adult. DESIGN Case report and literature review. SETTING Tertiary referral center. SUMMARY A 47-year-old female with a remote history of a skull fracture at 3 years of age presented with increasing headaches and retro-orbital pain. A computed tomogram and magnetic resonance image revealed a leptomeningeal cyst of the orbital roof. RESULTS Only one previous leptomeningeal cyst of the orbital roof has been reported in an adult. Surgical excision of the lesion was performed and follow-up imaging 18 months after the operation revealed no evidence of recurrence. CONCLUSION Although extremely rare, adult patients can develop growing skull fractures or leptomeningeal cysts of the orbital roof. Such lesions should be included in the differential diagnosis when a patient presents with orbital pain or exophthalmos and a history of head trauma as a child.

Abstract
OBJECTIVE In growing skull fractures with large calvarial defects, it is difficult to use autografts for reconstruction and it requires alternative materials for cranioplasty. In this report, the authors describe their experience and introduce reconstruction of the growing skull fractures' defects with a porous polyethylene sheet (Medpor) and with a novel technique of duraplasty with in situ galeal graft, which avoid the potentially risky dissection and exposure of brain tissue. The goal of this study was to clarify effective surgical methods and to provide the rationale for these techniques. METHODS We performed this technique on 8 patients with large calvarial defects resulting from growing skull fractures. The skin flap was retracted, leaving the galeal plane adherent to the underlying defect. After removing the bony edges and exposing the underlying retracted dural margins, duraplasty was performed by suturing the galeal tissue left in situ on the defect of the dural margins. Bone reconstruction was performed by placing porous polyethylene sheet (Medpor). CONCLUSIONS Duraplasty with in situ galeal tissue is a simple, safe, and effective technique to reconstruct dural defects in growing skull fracture, which avoids the risky dissection of the brain tissue. Also, by using Medpor, growing skull fractures can be effectively reconstructed with good cosmetic results.

Abstract
A 53-year-old female presented with a post-traumatic leptomeningeal cyst manifesting as bulging of the scalp, dizziness and tinnitus. She had known of the bulging of her forehead for about 20 years. She had suffered an injury to the head in childhood. Brain CT revealed a bone cyst associated with a round bone defect in the left frontal bone, bulging of the very thin outer layer and the defective inner layer. She was treated surgically with a diagnosis of skull tumour, but only gray cystic membranous tissue was found. The dural defect was repaired with fascia and the bone defect with bone cement. Bulging of the skull in adults can be caused by a bone cyst originating from a skull fracture.

Abstract
We describe a rare case of parietal intradiploic encephalocele in a 51-year-old woman with no history of head trauma. The patient presented with a 1-month history of left hemiparesthesia. A hard indolent scalp lesion was palpable on examination in the right parietal area. Skull x-rays and cranial computed tomography examination demonstrated a lytic lesion that was consistent with a malignant osteolytic skull lesion. Magnetic resonance imaging of the head revealed an intradiploic cyst that included a round tissue mass contiguous with the parietal cortex. Surgery confirmed the diagnosis of encephalocele and the patient underwent surgical resection of the herniated brain, duraplasty, and cranioplasty. The presenting hemiparesthesia persisted at the 6-month follow-up. Encephaloceles of the cranial vault are a rare complication of skull fractures and rarely occur in adults. These lesions can be difficult to distinguish from congenital encephaloceles in patients with no history of head trauma. The pathogenesis, clinical and radiological nuances and the role of surgery are discussed.

Abstract
BACKGROUND Growing skull fracture or craniocerebral erosion is a rare complication of linear skull fracture in childhood. It is characterized by progressive diastatic enlargement of the fracture line, which leads to a cranial defect, dural cleft, and cerebral herniation. It is presented as a soft pulsabile scalp swelling above the fracture, with a clear cranial defect. CASE REPORT In this paper we presented a patient, an 8-month-old boy with the growing skull fracture revealed four weeks after the injury. After the surgical treatment, the boy was in a good general condition without the presence of neurologic impairment. CONCLUSION Early recognition of craniocerebral erosion is very important. Timely detection prevents further progression of the disease and the evolution of neurological impairment. Surgery is the method of choice for treating a growing skull fracture.

Abstract
CONTEXT A case of a growing skull fracture presenting in adulthood is reported. Pertinent literature was reviewed with an emphasis on pathogenesis. EVIDENCE ACQUISITION A search through MEDLINE from 1994 through 2004 was used and supplemented by searches of secondary sources retrieved from referenced articles. EVIDENCE SYNTHESIS Current hypotheses for the pathogenesis of growing skull fractures were critically analyzed. A new hypothesis based in more recent data is proposed in an attempt to better understand this process. CONCLUSIONS The proposed hypothesis seems to explain better the timing in which the clinical features in growing skull fracture develop.

Abstract
Growing skull fractures (GSF) are rare complications of head injury (HI) in childhood. This entity consists of a skull fracture with an underlying dural tear that courses with a progressive enlargement of the fracture to produce a cranial defect. The pathophysiology and some aspects of its management are still controversial. In this review we present 12 patients diagnosedd and treated for a GSF at our institution between 1980 and 2002. 11 patients were under the age of 3 years and one patient was 5 years old at the moment of HI. The most common cause of injury was a fall from height. In the initial plain x-rayfilms, 11 patients showed a diastatic skull fracture and one patient only had a linear fracture. At this time, CT scan showed cortical contussion underlying the fracture in every case. The mean time between injury and presentation of GSF was 11.6 weeks. Diagnosis was made by palpation of the cranial defect and confirmed with skull x-rayfilms. The most frecuent location of GSF was in the parietal region. Associated lesions like hydrocephalus, encephalomalacia, lepto-menigeal cysts, brain tissue herniation and ipsilateral ventricular dilatation, were found in the preoperative CT or MRI. All patients underwent a dural repair with pericranium or fascia lata. The cranial defect was covered with local calvarial bone fragments in every case. Only one patient needed a cranioplasty with titanium mesh. Every child with a skull fracture must be followed until the fracture heals. Patients under the age of 3 years with a diastatic fracture and a dural tear, demostrated by TC or MRI, are more prone to develop GSF. In these cases, early repair must be adviced in order to prevent progressive brain damage.

Abstract
BACKGROUND Growing skull fractures rarely develop in the skull base region. To the best of our knowledge, only two similar cases have been reported in the English literature. This rare complication, which can occur even after a mild head injury, can produce exophthalmos and threaten the vision. METHODS The clinical and radiological findings of expanding leptomeningeal cysts extending into the orbit in nine patients referred to the department of Neurosurgery are presented. After appropriate investigations confirming the presence of the expansile retroglobal lesion, surgical exploration was performed via fronto-lateral or the preferred fronto-basal approach. The variable findings are denoted and the relevant literature is also reviewed. RESULTS Frontobasal head injuries play an important role in pathogenesis of these traumatic expansile leptomeningeal cysts. In this series of nine young girls, 6.65% (six out of nine) injuries happened in the first decade of life with an interval of 2 to 12 months (mean = 6.7, SD = 9.7). High-resolution coronal view computed tomography (CT) scanning with bone density window images, and high intensity cystic lesions visible on T2-weighted coronal MR images were diagnostic clues. CONCLUSIONS Growing fractures of the anterior skull base may complicate the natural course of healing of any minor frontobasal head injury, especially during childhood. Good quality imaging is mandatory in cases of progressive unilateral exophthalmos. Proper surgical intervention will lead to a good cosmetic result.
