A craniopharyngioma is a rare type of brain tumor derived from pituitary gland embryonic tissue [1] that occurs most commonly in children, but also affects adults. It may present at any age, even in the prenatal and neonatal periods, but peak incidence rates are childhood-onset at 5–14 years and adult-onset at 50–74 years. [2]
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
When molecular diagnostics are not complete enough to allow precise classification, diagnosis should be designated by appending not otherwise specified (NOS). In case of a full molecular workup which does not match any of the standard WHO diagnosis, tumors are to be labeled not elsewhere classified (NEC).
A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.
A definitive diagnosis often requires a tissue biopsy. The biopsy can be performed through an open surgical procedure or a minimally invasive stereotactic technique. [ 12 ] Histopathological examination determines the tumor type, grade, and molecular characteristics, which are critical for guiding treatment decisions.
CT scan of the brain showing a craniopharyngioma (white structure in the center of the image). This tumor may cause hypopituitarism and requires surgical removal. The diagnosis of hypopituitarism is made on blood tests. Two types of blood tests are used to confirm the presence of a hormone deficiency: basal levels, where blood samples are taken ...
Primitive neuroectodermal tumor is a malignant (cancerous) neural crest tumor. [1] It is a rare tumor, usually occurring in children and young adults under 25 years of age.. The overall 5 year survival rate is about
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
