Resumen
Los meningiomas de la fosa posterior suelen causar síntomas basados en su ubicación. Sin embargo, cuatro casos de grandes meningiomas infratentoriales presentaron sorprendentemente pocos signos clínicos.
Área de la Ciencia:
- La neurocirugía es la neurocirugía.
- Neurología Neurología.
- Oncología Oncología.
Sus antecedentes:
- Los meningiomas son tumores que surgen de las meninges.
- Los meningiomas de la fosa posterior se encuentran en la parte inferior de la base del cráneo.
- Estos tumores pueden crecer bastante antes de ser detectados.
Objetivo del estudio:
- Para investigar la presentación clínica de meningiomas de la fosa posterior inusualmente grandes.
- Resaltar las discrepancias entre el tamaño del tumor y la sintomatología observada en casos seleccionados.
Principales métodos:
- Revisión de la serie de casos de cuatro pacientes con grandes meningiomas infratentoriales.
- Análisis de registros clínicos, hallazgos de imágenes y exámenes neurológicos.
Principales resultados:
- Cuatro pacientes presentaron meningiomas infratentoriales masivos.
- A pesar de la carga tumoral significativa, los pacientes exhibieron manifestaciones clínicas mínimas o sutiles.
- Los déficits neurológicos fueron desproporcionadamente leves en comparación con el volumen tumoral.
Conclusiones:
- Los grandes meningiomas de la fosa posterior posterior pueden presentarse con signos clínicos atípicos y mínimos.
- La vigilancia diagnóstica es crucial, ya que las imágenes pueden revelar patologías significativas no evidentes en la evaluación clínica inicial.
- Esta presentación desafía la correlación típica entre el tamaño del tumor y la gravedad clínica en los meningiomas de la fosa posterior.

Cerebrum: Anatomical Overview I
6.0K
The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...

Anatomy of the Brain: Ventricles
10.0K
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.

Cranial Bones: Superior and Posterior View
8.3K
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,...

Cranial and Spinal Meninges
4.4K
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...

Cranial Bones: Lateral View
7.6K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
