Other common locations include the adrenal gland, paraspinal retroperitoneum, posterior mediastinum, head, and neck. [1] It is contained within the neuroblastic tumors group, which includes: [3] Ganglioneuroma (benign), Ganglioneuroblastoma (intermediate), Neuroblastoma (aggressive).
Spinal and peripheral nerve sheath tumors may lead to a variety of symptoms depending on tumor type, location, and severity, though they do share some symptoms. [1] Some common findings for all nerve sheath tumors include: Pain [1] [6] Numbness [6] Tingling [6] Burning sensation [6] Weakness [6] Visible or palpable mass [6]
Symptoms may include: Swelling in the extremities (arms or legs), also called peripheral edema; the swelling often is painless. Difficulty in moving the extremity that has the tumor, including a limp. Soreness localized to the area of the tumor or in the extremity. Neurological symptoms. [3] Pain or discomfort: numbness, burning, or "pins and ...
Other common symptoms include muscle weakness, sensory loss, and difficulty walking. [1] Loss of bowel and bladder control may occur during the later stages of the disease. [3] The cause of spinal tumors is unknown. Most extradural tumors are metastatic commonly from breast, prostate, lung, and kidney cancer. [4]
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.
Most paragangliomas are asymptomatic, present as a painless mass, or create symptoms such as hypertension, tachycardia, headache, and palpitations. [3] While all contain neurosecretory granules, only in 1–3% of cases is secretion of hormones such as catecholamines abundant enough to be clinically significant; in that case manifestations often resemble those of pheochromocytomas (intra ...
Pleural schwannoma typically shows fatty degeneration, hemorrhage, perivascular hyalinization, and cystic formation thus giving heterogenous hyperintensities on T2 weighted images. Complete surgical removal of pleural schwannoma is the usual treatment. [11] Cellular schwannoma is a relatively rare variation. Cellular schwannoma is nearly ...
Various kinds of tumors, usually primary and benign, are represented in the pathology. Lesions in the area of cerebellopontine angle cause signs and symptoms secondary to compression of nearby cranial nerves, including cranial nerve V (trigeminal), cranial nerve VII (facial), and cranial nerve VIII (vestibulocochlear). The most common ...
