The pathological features associated with spinal tumours in 29 dogs

Area of Science:

• Neurosurgery
• Pathology
• Oncology

Background:

• Spinal tumors represent a diverse group of neoplasms affecting the vertebral column and spinal cord.
• Understanding the pathological spectrum and origin of these tumors is crucial for diagnosis and treatment planning.

Purpose of the Study:

• To describe the pathological features of a series of 29 spinal tumors.
• To identify the most common types and origins of spinal neoplasms within this cohort.

Main Methods:

• Retrospective analysis of pathological features from 29 surgically treated spinal tumors.
• Classification of tumors based on origin (extradural, intradural-extramedullary, intramedullary) and histological type.

Main Results:

• The most frequent tumors originated extradurally, including 10 vertebral neoplasms and 2 lymphosarcomas.
• Peripheral nerve tumors invading the spinal cord accounted for 10 cases.
• Other identified tumors included meningiomas (3), ependymomas (2), metastatic mammary adenocarcinoma (1), and haemangiosarcoma (1).
• A significant absence of glial tumors was noted in this series.

Conclusions:

• Extradural neoplasms and peripheral nerve tumors are common in spinal pathologies.
• The observed distribution highlights specific epidemiological trends in spinal tumor origins.
• The lack of glial tumors warrants further investigation into potential biases or specific patient populations.
