Introduction Under the ependymoma, the tumor cells were consistent in size and shape, fusiform or carrot-shaped, rich in cytoplasm, round or elliptical in shape, with daisy-shaped or pseudo-purple-shaped clusters.

Cause

Ependymoma is a neuroepithelial tumor with a special tissue structure. Its most important histopathological features are the perivascular pseudo-purple group and the ependymaloid.

Tumor cells are connected to the vessel wall by elongated cells to form a transected papillary structure.

Differential diagnosis

Symptoms of neuroepithelial neoplasia can be divided into nose, nerves, mouth, face, neck, and ophthalmology, and are divided as follows:

Nasal - obstruction (70%), nosebleeds (46%), discharge, unilateral polyps, smell

Nerves - headache, nausea

Ophthalmology - Eyeballs, eye movement paralysis, blindness, appearance between the first symptoms and diagnosis of an average delay of 6 months, but in some cases diagnosed, delayed for several years. Delays are understandable because the initial symptoms are often subtle and often mediocre, as well as common diseases in the nasal cavity, including long-term sinusitis or allergic polyp sinus disease.
