20210031 | Reportability--Brain and CNS: Are lipomas of the spinal column reportable as a benign tumor of the central nervous system (CNS)? This is seen occassionally at our pediatric facility. |
Spinal cord tumors (including lipomas) are reportable when they arise in the spinal dura or nerve root. The tumor must be of the spinal cord itself or within the spinal cord dura. Spinal cord tumors are reportable when they arise in the intradural space. A reportable intradural tumor can be either intramedullary or extramedullary. Extramedullary intradural spinal tumors are reportable. A spinal tumor originating in the extradural space is not reportable. If it is outside the dura, it is not reportable because it would be outside the CNS. They are not reportable when they arise in the peripheral nerves. |

20160068 | Reportability--Brain and CNS: Are sphenoid wing meningiomas reportable? See discussion. |
It's my understanding that true intraosseous meningiomas are very rare. It's also my understanding that cranial meninges DO cover the sphenoid wing, so I'm wondering if it's possible to have a meningioma of the sphenoid wing on imaging that arises from the meninges NOT the bone. Is that the deciding factor on reportability? It's been suggested to me that meninges cells do lie within the bone, but again if a meningioma is described as being located at the sphenoid wing on imaging, without bone involvement - and no surgery is performed - I do not understand why it is specifically excluded as non-reportable. |
This answer pertains to cases diagnosed prior to 2018. For 2018 and later cases, refer to the Non-Malignant CNS Solid Tumor Rules. Note: This answer updates previous answers which have been removed from the SEER Inquiry System. Intraosseous meningiomas are not reportable. You are correct, these are rare meningiomas originating in bone. The term "sphenoid wing meningioma" is sometimes used for an intraosseous meningioma of the sphenoid bone. Yes, it's possible to have a meningioma of the sphenoid wing on imaging that arises from the meninges NOT the bone. Read the available information carefully. When the site of origin is described as "along the sphenoid wing" or "overlying the sphenoid wing" report the meningioma. These descriptions indicate that the meningioma originates from the meninges covering bone rather than the bone itself. Meningioma arising in bone is rare enough, that when present, we would expect it to be clearly stated as such. In the absence of a statement indicating origin in bone, the meningioma is most likely arising from meninges covering the bone. |

20130189 | Reportability--Brain and CNS: Are the terms 'mass' and 'lesion' reportable terms for accessioning brain and CNS primaries? See Discussion. |
With respect to reportability, the SEER Manual mentions 'tumor' and 'neoplasm,' but not 'mass' or 'lesion.' The SEER MP/H Manual states tumor, mass, lesion and neoplasm are equivalent terms for determining multiple primaries, but does this apply to reportability? If not, what is the distinction? |
'Mass' and 'lesion' are not reportable terms for benign/borderline brain and CNS tumors. Reportable terms for benign/borderline brain and CNS primaries are 'tumor' and 'neoplasm.' These terms appear in the ICD-O-3. 'Lesion' and 'mass' do not appear in the ICD-O-3. Do not use the MP/H Manual to determine reportability; page 2 of the SEER Manual is the correct source for reportability instructions. |

20180013 | Reportability--Brain and CNS: Are tuberous sclerosis cancers found in the brain reportable? See Discussion. |
I have searched ICD-O-3 for a histology listing but could not locate. I also searched the SEER Inquiry database for possible answers, but none were found. The patient underwent a pediatric MRI of the brain of which final impression was: 1) Subependymoma nodules, cortical tubers, and SEGAs are seen bilaterally consistent with tuberous sclerosis. |
SEGA (Subependymal giant cell astrocytoma) is reportable if diagnosed in 2004 or later. Tuberous sclerosis complex (TSC) is not a neoplasm and is not reportable. SEGA is a neoplasm that commonly occurs in TSC patients. Refer to the reportability instructions on pages 5-7 in the SEER manual, https://seer.cancer.gov/manuals/2016/SPCSM_2016_maindoc.pdf |

20071132 | Reportability--Brain and CNS: Does a neurofibroma actually arise in peripheral nerve roots like a schwannoma even if it is referred to as a "C6-T1 intradural spinal cord tumor" and is therefore not reportable? |
Schwannomas and neurofibromas of the peripheral nerves are not reportable. Schwannomas of the nerve root or spinal dura are reportable. |

20081113 | Reportability--Brain and CNS: Is a cavernoma reportable as a benign brain tumor? See Discussion. |
Cavernous hemangiomas are typically described as vascular malformations in the brain. Per a search of the literature, cavernoma, cavernous hemangioma and cavernous malformation are all synonymous. There is some controversy as to whether cavernomas are vascular malformations or tumors. Cavernous hemangioma (9121/0) has been assigned a code in the ICD-O-3. The other terms are not even listed. Benign brain guidelines indicate that named tumors that have been assigned an ICD-O-3 code are reportable. Would we report a lesion that is labeled cavernous hemangioma but not one that is labeled carvernoma? Are cavernous malformations of the brain to be reported as benign brain tumors? The MP/H guidelines for benign brain tumors do not include blood vessel tumors in chart 1. Are the following tumors reportable? If so, what is the primary site? Example 1: Patient admitted for resection. Clinical diagnosis is left temporal cavernous hemangioma. Path diagnosis is cerebral cortex and white matter showing cavernoma. Example 2: Patient admitted for resection with clinical diagnosis of parietal cavernous hemangioma. Path shows A-V malformation. Example 3: Patient had T4 spinal tumor removed. Path showed cavernous angioma. Reference: I&R 18109 and 23460 |
Cavernoma is a reportable benign brain tumor. According to our pathologist consultant, cavernoma is synonymous with cavernous hemangioma. Examples 1. Reportable. Primary site - C710 [cerebrum] 2. Not reportable. Path dx disproves clinical diagnosis. 3. Not reportable. Not a brain tumor. |

20160018 | Reportability--Brain and CNS: Is a colloid cyst at the foramen of Monro reportable? |
Colloid cyst at the foramen of Monro is not reportable. Colloid cysts are endodermal congenital malformations and do not have an ICD-O-3 code. See the Glossary for Registrars, http://seer.cancer.gov/seertools/glossary/view/542eeea1102c1d14697ef8ab/?q=colloid |

20041069 | Reportability--Brain and CNS: Is a meningioma invading the bone malignant and, therefore, SEER reportable if diagnosed prior to 2004? See Discussion. |
1. Meningothelial meningioma with prominent nuclear pleomorphism, infiltration into dura, calvarium, temporalis skeletal muscle. Microscopic: Multifocal infiltration by meningothelial tumor...extensive infiltration of trabecular spaces, extension through inner and outer calvarial layers by meningioma...mitotic activity in tumor noted but below the 4 per 10 high power field threshold for diagnosis of atypical meningioma. 2. Aggressive (invasive) transitional type meningioma, neuroimaging and histology imply extensive invasive meningioma involving bone and paraspinal soft tissues. Microscopy:...invaded bone...focal EMA positivity diagnostic of invasive transitional type meningioma... tumor invades bone. |
The two cases above are benign meningiomas and not reportable prior to 2004. According to an expert consultant, meningiomas are in the lining cells for the inner table of the skull and as such have an affinity for bone that allows them to penetrate adjacent bone without being "malignant." The WHO Nervous System Tumor Classification states malignant meningioma exibits histological features of frank malignancy far in excess of the abnormalities present in atypical meningioma (WHO grade II). Examples of the histologic features of malignant meningioma are obviously malignant cytology, or high mitotic index (20 or more mitoses per 10 high-power fields). They correspond to WHO grade III and are usually fatal. |

20041097 | Reportability--Brain and CNS: Is a skull tumor schwannoma an intracranial reportable benign tumor if the physician states it arose in the occipital nerve? |
No. These schwannomas are not intracranial and therefore, are not reportable to SEER. The occipital nerve is not one of the 12 intracranial nerves (i.e., Abducens, Auditory (vestibulocochlear), Facial, Glossopharyngeal, Hypoglossal, Oculomotor, Olfactory, Optic, Spinal Accessory, Trigeminal, Trochlear, and Vagus). |

20200041 | Reportability--Brain and CNS: Is an intradural T12/L1 capillary hemangioma reportable? See Discussion. |
Example: MRI found an intradural, extra-axial mass at T12/L1 with possible intramedullary component. Resection of the intradural intramedullary and extramedullary spinal cord tumor found a capillary hemangioma pathologically. The microscopic description on the path report describes a tumor with extensive vascularity involving the dura. Should we equate the statement of capillary to mean the tumor is arising in a blood vessel as we do for venous hemangioma (non-reportable per SINQ 20130001)? Or should it be reportable as C700, 9131/0 because it is described as involving the dura (intradural, intramedullary and extramedullary)? |
Reportability of capillary hemangioma depends on the site of origin. If it originates in the dura, it is reportable. If it originates in a blood vessel, it is not reportable. The site of origin is not clear in the information provided. Sites of involvement are mentioned, but not the site of origin. Capillary could refer to the site of origin or to the propensity of this tumor to form tiny blood vessels. If the site of origin cannot be confirmed as dura, do not report this neoplasm. |
