The metastatic tumor cells grow either attached to the pia mater covering the brain and spinal cord or floating unattached to the subarachnoid space. [7] Tumors of diverse origins and hematologic cancers may spread to this space. [5] Some patients can develop a leptomeningeal tumor while receiving chemotherapy for their primary tumor.

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare, primary CNS tumor, classified as distinct entity in 2016 [1] and described as diffuse oligodendroglial-like leptomeningeal tumor of children in the 2016 classification of CNS neoplasms by the WHO., [2] Typically, it's considered juvenile tumors [3] but can occur in adults, [4] the average age of diagnosis is five years. [3]
These processes tend to cause seizures early in the course because of their cortical location. Metastasis to the leptomeninges is an uncommon but well-recognized clinical presentation in cancer patients. Leptomeningeal metastasis most commonly is due to breast, lung, or melanoma primary tumors. [2]
Metastasis is the most common cause of brain cancer, as primary tumors that originate in the brain are less common. [4] The most common sites of primary cancer which metastasize to the brain are lung, breast, colon, kidney, and skin cancer. Brain metastases can occur months or even years after the original or primary cancer is treated.
Life expectancy in the U.S. is projected to increase from 78.3 years in 2022 to 79.9 years in 2035 and to 80.4 years in 2050 for all sexes combined, researchers said.
The ASCO study of the 188 documented AT/RT cases prior to 2004 found 30% of the cases had metastasis at diagnosis. [3] Metastatic spread to the meninges (leptomenigeal spread sometimes referred to as sugar coating) is common both initially and with relapse. Average survival times decline with the presence of metastasis.

The life expectancy in some states has fallen in recent years; for example, Maine's life expectancy in 2010 was 79.1 years, and in 2018 it was 78.7 years. The Washington Post noted in November 2018 that overall life expectancy in the United States was declining although in 2018 life expectancy had a slight increase of 0.1 and bringing it to ...
