Microsurgical Resection of Tumor of the Lateral Ventricle:

The surgical management of tumors of the lateral ventricles (LV) and the third ventricle (TV) remains a distinct challenge for neurosurgeons due to the deep and difficult-to-reach location and frequent involvement of adjacent critical neurovascular structures. An appropriate surgical approach should provide adequate operative working space with minimal brain retraction or brain transgression. To accomplish these goals, neurosurgeons may choose an approach that necessitates a longer distance to reach the tumor if it minimizes the amount of brain tissue that is resected or placed at risk by the approach. Furthermore, selection of the optimal approach to ventricular tumors depends on multiple other factors including the size of the ventricles and the tumor, the location of the arterial supply, pathological features of the tumor, and the surgeon’s experience. This video provides an overview of the open surgical operative corridors to the lateral tumors, highlighting the key surgical principles.

¿Es lo mismo tumor y cáncer?

Un cáncer es un tumor, pero no todos los tumores son cánceres…

Se llama tumor a toda estructura formada por el aumento de tamaño de un tejido a consecuencia de la reproducción incontrolada de un conjunto de células del mismo.

Se dice que un tumor es benigno cuando las células que lo forman permanecen unidas, formando una masa compacta que frecuentemente incluso se encuentra rodeada por una membrana de contención.

El cáncer o tumor maligno, por el contrario…

Hyperparathyroidism occurs when the parathyroid glands make too much parathyroid hormone (PTH). The parathyroid glands are four pea-sized endocrine glands located in your neck, near or attached to the back of your thyroid. Endocrine glands secrete hormones necessary for the normal functioning of the body. 

Despite having similar names and being adjacent in your neck, the parathyroid glands and the thyroid are very different organs. PTH helps regulate the levels of calcium, vitamin D, and phosphorus in your bones and blood.

These are photographies of teratoma tumors. A teratoma is a tumor containing a variety of different cells, caused by the tumor replicating cells of the human body it “naturally” should not. The teratoma is often congenital, but may not show signs of existence until later in life. Teratomas are known to contain teeth and hair (as in the pictures), bone, and in uniquely rare cases, more complex parts such as eyes, hands, and feet.

Japanese Doctors find Brain and Skull inside Teen’s Ovarian Tumor [Teratoma]:
During surgery to remove a 16-year-old girl’s appendix, surgeons discovered a surprise guest - a tumor with a brain, hair and neurons that could transmit electric impulses like a normal brain.
The nearly 4-inch-wide tumor also had a thin plate of skull bone covering the 1.18-inch brain, which included a tiny version of a cerebellum and a mass that resembled a brain stem, New Scientist reported.
While it’s not uncommon for brain cells to be found in ovarian teratomas - tumors that contain foreign tissue including hair, teeth, cartilage, fat and muscle - this patient’s situation was unusual.

An X-Ray of an individual who has a teratoma, shown to the left of the mediastinum just superior to the heart. Teratomas are tumors have the hallmark of consisting of tissues not normally present at their site of growth and have been known to grow things such as hair, or sometimes more complex processes such as eyes. In the teraroma pictured above the opacities are teeth.

Carcinoid syndrome refers to the array of symptoms that occur secondary to carcinoid tumors. The syndrome includes flushing and diarrhea, and, less frequently, heart failure and bronchoconstriction. It is caused by endogenous secretion of mainly serotonin and kallikrein.

A carcinoid tumor often begins in the stomach, appendix, small intestine, colon, rectum, or lungs. Symptoms often don’t appear until late in the disease and are vague.
