Spinal Cord Transplantation – Inclusion Tumors

Spinal cord inclusion tumors are rare spinal cord tumors. These tumors are remnants of embryonic life. Lipoma, epidermoid tumor, dermoid tumor and teratoma There are different types including >. It is a benign tumor. They grow and cause spinal cord compression.

SPINAL CORD EPIDERMOID TUMORS

These are rare spinal cord tumors. Epidermoid tumors constitute a very rare part of all spinal canal tumors. Although they can be seen in every region, they are most frequently found in the dorsal spinal cord region. These tumors may occur congenitally (as a result of incorrect placement of ectodermal cells during neural tube closure in the 3rd and 5th weeks of embryonic development) or later (as a result of lumbar punctures or injections from the waist). Skin defects such as dermal sinus tract may be seen in congenital cases. On Magnetic Resonance Imaging, epidermoid cysts appear as well-circumscribed masses that do not cause peripheral edema. In T1-weighted images, epidermoid tumors are seen at the same intensity (hypointense) as the CSF, and in T2-weighted images they are seen as the same intensity (hyperintense) as the CSF. Tumor tissue can usually be easily removed during surgery. Epidermoid tumors are encapsulated lesions with smooth or lobulated surfaces. There are pearl white appearances during surgery. Although it is a benign tumor, regrowth may occur due to residual tumor tissue. The tumor capsule usually shows tight adhesions to the surrounding neural tissue. Removal may cause damage to nerve tissues.

SPINAL CORD DERMOID TUMORS

Dermoid tumors appear as round masses with well-circumscribed borders. It usually has a dense yellowish fluid and a cystic center that may contain hair. Unlike epidermoid tumors, hair follicles and sweat gland remnants are seen in the tumor capsule wall. The yellowish content is the content secreted by the sebaceous glands. In Magnetic Resonance Imaging, dermoid tumors are hyperintense because they contain dense cholesterol accumulation and septic gland secretions. ns is seen. T2-weighted dermoid tumors appear hypointense. The cause of homogeneous or heterogeneous signal changes in Magnetic Resonance Imaging depends on the fluid, fat and protein content of the tumor tissue. The intervention site should be determined according to tumor location. Since they are benign tumors, total resection should be planned. The tumor capsule usually shows tight adhesions to the surrounding neural tissue. Therefore, capsule resection may be risky in some cases. As much tumor tissue as possible should be removed.

SPINAL CORD TERATOMAS

Spinal intradural teratomas are very rare lesions and these tumors are associated with spinal anomalies. can be seen together. It is usually seen in young patients and occurs equally frequently in both genders. Spinal cord teratomas are usually located in the neck, lower back and upper lumbar region. These tumors contain solid and cystic components. They may also be associated with syringomyelia. Teratomas contain ectodermal, mesodermal and endodermal structures. Immature teratomas have cells originating from all three germinal layers or any of these germinal layers. The possibility of completely removing the mass is very low. On Magnetic Resonance Imaging, they appear as masses of mixed signal intensity with solid and cystic components.

SPINAL CORD LIPOMAS

Lipomas are masses composed of fat cells. They are not true tumors. They are not truly tumors. As a result of defective embryogenesis, normal cells reproduce. They develop not from a single cell type, but from all embryological layers. They may be located inside or outside the spinal cord. There are types such as lipomyeloningocele (conus medullaris lipoma), fatty filum (terminal filum lipoma), intradural spinal lipoma (spinal cord lipoma), epidural lipomatosis and spinal angiolipoma. However, spinal cord lipomas are fatty accumulations located entirely within the spinal cord membrane and have no connection with the skin. They tend to be located on the back of the spinal cord. 4% of lipomas are generally found in the thoracic region. It is found in the neck area in children. It does not discriminate based on gender. They are difficult to remove completely due to their very tight connection with the spinal cord. Sometimes during surgery It may be difficult to distinguish between urinate. Mostly, tumor evacuation - internal decompression is applied.
