Case Report: A 3-year-old girl was transferred to our hospital with a history of persistent open anterior fontanel. The patient was conscious and had no neurological deficits. Upon arrival, the patient appeared normal for her age and had no defects or anomalies other than the aforementioned lesion. The initial skull X-ray and CT were significant for a 20-mm open anterior fontanel. All other findings were normal.
Outcome: After a follow-up period of 1.5 years, the anterior fontanel was still open, with a slight decrease in size to 15 mm. Delayed closure of the anterior fontanel without intracranial hypertension is associated with various disorders. The pathogenesis of the current patient's condition is unclear. Due to the patient's normal appearance and stable neurological status, we will follow her conservatively for any changes in condition.

Kenny-Caffey syndrome 2 (KCS2) is a rare cause of hypoparathyroidism, inherited in an autosomal dominant mode, resulting from pathogenic variants of the gene, which is implicated in intracellular pathways regulating parathormone (PTH) synthesis and skeletal and parathyroid gland development. : The case of a boy is reported, presenting with the characteristic and newly identified clinical, biochemical, radiological, and genetic abnormalities of KCS2. : The proband had noticeable dysmorphic features, and the closure of the anterior fontanel was delayed until the age of 4 years.

The calvarial bones of the infant skull are linked by transient fibrous joints known as sutures and fontanelles, which are essential for skull compression during birth and expansion during postnatal brain growth. Genetic conditions caused by pathogenic variants in FGFR2, such as Apert, Pfeiffer, and Crouzon syndromes, result in calvarial deformities due to premature suture fusion and a persistently open anterior fontanelle (AF). In this study, we investigated how Fgfr2 regulates AF closure by leveraging mouse genetics and single-cell transcriptomics.

Background: Familial chylomicronemia syndrome (FCS) is a rare genetic disorder with heterogeneous presentation, where acute encephalopathy is rarely described in literature. Therefore, initial neurologic symptoms could make the diagnosis and treatment challenging.
Case Presentation: A four-month-old male infant presented with acute encephalopathy, vomiting, bulging fontanel, decreased appetite and failure to thrive.

Objective: Subdural fluid collection is a common neurosurgical condition in the pediatric population. Patients requiring surgical intervention have historically been managed with subdural drains, subdural-subgaleal shunting, subdural-peritoneal shunting, and mini-craniotomies. An alternative procedure for patients with an open anterior fontanelle is bedside transfontanelle drainage.

This case report presents a novel treatment approach for refractory purulent meningitis in a 1-month-old infant caused by penicillin-sensitive group B Streptococcus. Despite initial treatment with intravenous antibiotics, including penicillin and vancomycin, the infant experienced persistent symptoms and bilateral subdural effusions. Conventional therapies failed to resolve these issues, leading to the use of a new technique: subarachnoid puncture via the anterior fontanelle combined with intrathecal vancomycin administration.
