Insights

A rare intradiploic epidermoid cyst in an infant

Area of Science:

  • Pediatric Neurosurgery
  • Dermatopathology
  • Radiology

Background:

  • Intradiploic epidermoid cysts are uncommon skull lesions in infants.
  • Early diagnosis and management are crucial for favorable outcomes.

Observation:

  • A 7-month-old girl presented with a 1.5 cm scalp lump.
  • Initial suspicion of Langerhans cell histiocytosis (LCH) was ruled out by systemic tests.
  • Radiological imaging revealed a lytic lesion in the left parietal bone.

Findings:

  • CT scans indicated an intradiploic mass with outer table erosion.
  • Histological examination confirmed an epidermoid cyst after surgical excision.
  • The lesion demonstrated progressive enlargement.

Implications:

  • This case highlights the importance of considering epidermoid cysts in the differential diagnosis of infantile scalp masses.
  • Prompt neurosurgical intervention is necessary for definitive diagnosis and treatment.
  • Understanding the clinical presentation and imaging features aids in managing these rare pediatric skull tumors.

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Brain Abscess l: Introduction01:26

Brain 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,...

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
