Neurulation01:30

Neurulation

44.8K
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...

Anatomy of the Brain: Ventricles

7.5K
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.

Brainstem01:19

Brainstem

5.3K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

Cranial and Spinal Meninges

3.3K
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...

Veins of Head and Neck01:19

Veins of Head and Neck

4.9K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Summary

Neurenteric cysts are rare neuroaxis lesions. This case highlights a recurrent posterior fossa neurenteric cyst, emphasizing the rarity of intraoperative imaging and cytology in literature.

Area of Science:

  • Neurology
  • Pathology
  • Neurosurgery

Background:

  • Neurenteric cysts, also known as endodermal or enterogenous cysts, are uncommon neuroaxis lesions.
  • These cysts predominantly occur in the spinal cord, with intracranial occurrences being rare.
  • Intraoperative imaging and cytology of these lesions are infrequently documented in medical literature.

Purpose of the Study:

  • To describe a rare case of a recurrent posterior fossa neurenteric cyst.
  • To present intraoperative findings, cytologic, and histologic features of this cyst.
  • To illustrate the utility of intraoperative macroscopic and cytologic images in understanding recurrent neurenteric cysts.

Main Methods:

  • Case report of a 47-year-old female with a recurrent posterior fossa neurenteric cyst.
  • Detailed description of intraoperative findings.
  • Presentation of cytologic and histologic analyses of the cyst.

Main Results:

  • The cyst presented as a recurrent posterior fossa lesion compressing the brainstem.
  • The patient experienced symptoms of incontinence and progressive quadriparesis.
  • Intraoperative images and cytology provided valuable diagnostic information.

Conclusions:

  • Neurenteric cysts are typically benign and slow-growing, but recurrence is a known characteristic.
  • This case underscores the importance of intraoperative visualization and cytology in managing recurrent neurenteric cysts.
  • The presented images contribute to the limited literature on intraoperative aspects of these rare cysts.
