Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

1.8K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Sutures of the Skull01:22

Sutures of the Skull

8.2K
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...

Anatomy of the Brain: Ventricles

5.5K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Neurulation01:30

Neurulation

43.0K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Summary

Paleopathology reveals meningiomas (central nervous system tumors) can cause bone changes like hyperostosis. These tumors, though rare in ancient records, should be considered in differential diagnoses for skeletal lesions.

Area of Science:

  • Paleopathology
  • Neuropathology
  • Skeletal Biology

Background:

  • Meningiomas are common central nervous system tumors.
  • They can cause significant skeletal changes, including hyperostosis, enostoses, depressions, and vascular impressions.
  • Identification of meningiomas in paleopathological literature is infrequent and often debated.

Purpose of the Study:

  • To review and analyze reported cases of meningiomas in paleopathological literature.
  • To assess the diagnostic criteria and frequency of meningiomas in ancient skeletal remains.
  • To emphasize the importance of considering meningiomas in differential diagnoses for skeletal lesions.

Main Methods:

  • Literature review of paleopathological cases attributed to meningiomas.
  • Analysis of reported skeletal manifestations, including size, location, and type of lesion.
  • Comparison of findings with known characteristics of meningiomas.

Main Results:

  • Identified 43 cases of suspected meningiomas in the literature.
  • Hyperostosis was the most recognizable indicator, averaging 8 cm in diameter and 3.0 cm in height, often on the parietal bone.
  • Other manifestations included lytic lesions, vascular changes, sclerotic lesions, and hollow areas, with varied presentation and size.

Conclusions:

  • Meningioma-induced skeletal changes are non-pathognomonic, leading to diagnostic challenges.
  • Despite rarity in paleopathological records, meningiomas likely affected ancient populations.
  • Meningiomas should be more frequently considered in the differential diagnosis of ancient skeletal lesions.
