Resumen
Un raro quiste neuroepitelial en un niño se presentó inusualmente con trastornos del movimiento, no los típicos síntomas silenciosos. Este caso pone de relieve la importancia de la resonancia magnética en el diagnóstico de estas lesiones cerebrales raras.
Área de la Ciencia:
- Neurología Neurología.
- Neurología Pediátrica.
- Neuroradiología Neuroradiología.
Sus antecedentes:
- Los quistes neuroepiteliales son lesiones intracraneales benignas y raras.
- Por lo general, son asintomáticos y se encuentran incidentalmente.
- La presentación con déficits neurológicos, especialmente trastornos del movimiento, es poco común.
Objetivo del estudio:
- Para informar de un caso inusual de un quiste neuroepitelial pediátrico que se presenta con un trastorno del movimiento.
- Para ilustrar la utilidad diagnóstica de la resonancia magnética en la caracterización de tales lesiones.
- Ampliar la comprensión del espectro clínico de las lesiones quísticas de los ganglios basales.
Principales métodos:
- Informe de caso de una niña de 12 años con debilidad progresiva de la extremidad superior izquierda y movimientos involuntarios.
- Se realizó una resonancia magnética cerebral para evaluar la lesión.
- Los hallazgos radiológicos se correlacionaron con la presentación clínica.
Principales resultados:
- En la resonancia magnética se identificó una lesión quística intraparenquimal bien definida en el ganglio basal derecho.
- La lesión exhibió características de señales similares al líquido cefalorraquídeo y ninguna mejora de contraste.
- Los síntomas del paciente de mioclono y distonía fueron atribuidos a este quiste.
Conclusiones:
- Los quistes neuroepiteliales pueden manifestarse como trastornos complejos del movimiento, incluso en pacientes pediátricos.
- La resonancia magnética es crucial para la caracterización de las lesiones quísticas intracraneales.
- Este caso amplía el espectro de presentación clínica de las lesiones quísticas intraparenquimales de los ganglios basales.

00:55Laminins are the Adhesive Proteins of Basal Lamina
3.4K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

16.3K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

02:18Intrinsically Disordered Proteins
19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

01:03Basal Lamina are the Specialized Form of ECM
3.9K
The basal lamina is a thin extracellular layer that lies underneath the cells and separates them from other tissues. The three layers of the basal lamina are lamina lucida, lamina densa and lamina reticularis. The basal lamina, a mixture of glycoproteins and collagen, provides an attachment site for the epithelium, separating it from underlying connective tissue. The framework of basal lamina has other essential proteins such as laminins mesh, perlecan, entactin, and type IV collagen.

01:05Type IV Collagen of Basal Lamina
3.1K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.

01:43The Movement of Organelles and Vesicles
6.6K
In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...
