Summary
Periorbital dermoid cysts, typically benign, can rarely extend into the skull. Two cases show delayed transcranial extension after initial apparent resolution, requiring complex surgical excision.
Area of Science:
- Ophthalmology
- Neurosurgery
- Pediatric Surgery
Background:
- Periorbital dermoid cysts are common congenital tumors.
- They usually present as mobile, well-circumscribed masses near the lateral brow.
- Superficial, nonmidline, periorbital dermoid cysts rarely show transcranial extension.
Observation:
- Two cases of lateral brow dermoid cysts initially recognized in newborns are presented.
- These cysts appeared clinically resolved over time.
- Later, they presented with significant bone erosion and intracranial extension.
Findings:
- Delayed transcranial extension of periorbital dermoid cysts can occur.
- This extension involves full-thickness bone erosion.
- Combined extracranial and intracranial surgical approaches are necessary for excision.
Implications:
- Highlights the potential for delayed complications of seemingly resolved dermoid cysts.
- Emphasizes the need for long-term monitoring of periorbital lesions.
- Informs surgical planning for complex orbitofacial tumor management.

01:53Cause and Effect
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?
01:22Sutures 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...

01:21Dissociative Amnesia
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...
01:29Magical Thinking
Magical thinking encompasses the belief in assumptions that defy logical reasoning yet appear intuitively convincing. It is a common psychological phenomenon that persists across various cultural and individual contexts. While these assumptions contradict empirical evidence and scientific laws, they often serve meaningful psychological roles in promoting emotional resilience and a sense of control, especially under stress or uncertainty.Thought-Action Fusion and the Law of SimilarityA key...
