Summary
Forehead lipomas penetrating bone to the dura are rare in children. These post-traumatic pseudolipomas may arise after forceps delivery and should be considered in congenital forehead lesion diagnoses.
Area of Science:
- Pediatric Surgery
- Neurology
- Dermatology
Background:
- Forehead lipomas are uncommon in pediatric patients.
- Deeply invasive lipomas attaching to the dura mater have not been previously documented in children.
Observation:
- Two cases of congenital forehead lesions are presented in infants delivered via forceps.
- Initial clinical and imaging evaluations (CT, MRI) suggested dermoid cysts.
- Histopathology confirmed fibrofatty tissue, consistent with lipoma.
Findings:
- The lesions extended subcutaneously, through the frontalis muscle and frontal bone, to the dura mater.
- A history of forceps delivery was noted in both cases.
- The most probable diagnosis is post-traumatic pseudolipoma.
Implications:
- This condition should be included in the differential diagnosis for congenital forehead masses in infants.
- A history of birth trauma, such as forceps delivery, is a key indicator for considering this diagnosis.
- Highlights the importance of histopathological examination for definitive diagnosis of rare pediatric head lesions.

01:28Traumatic Brain Injury l: Introduction
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
