Abstract

Introduction: Spinal tumours of the spine constitute around 15-20% of CNS tumours. It can


be localized into three compartments- extradural, intradural extramedullary and


intramedullary. Once the lesion is localized, a differential diagnosis can be established based


on the tumours that commonly occur in that compartment. These lesions have characteristic


magnetic resonance imaging features for a definitive diagnosis. The present study aims to


evaluate spectrum of spinal tumours and correlate MRI imaging with pathological findings.


Material and Methods: The present study included 48 patients and was conducted on 3 Tesla


MRI. The patients who had back pain and neurological symptoms & were diagnosed as spinal


tumours on FNAC/ Biopsy were included. The routine MRI protocols included T1WI & T2WI


sagittal and axial, STIR coronal and sagittal images; slice thickness was 3.0 mm; field of view


(FOV) was 28 - 32 cm and contrast enhanced axial, sagittal and coronal T1W fat sat images.


The images were assessed for location, shape, extent, component characteristics, signal


intensities on different MRI sequences and enhancement patterns of the lesions. The lesions


were correlated with cytohistopathological findings.


Results: Male predominance (2.7:1) with common age group 41-50 years with mean age of 43


years was seen. The male: female ratio in malignant and benign was 1:1.8 and 1:6 respectively.


Most common location of tumours was intradural extramedullary (54.16%), followed by


Extradural (37.5%) and intramedullary spinal cord tumour (6.25%). Most common location


was dorsal (52.08%). The most common spinal tumour was metastasis followed by nerve


sheath tumours. On correlation of MRI finding with cytohistopathology sensitivity and


specificity for malignant lesion was 85.71% and 96.29 % respectively, while for benign lesion


was 96.29 % and 85.71% respectively.


Conclusion: Magnetic resonance imaging is useful in effectively defining the size, shape and


position of tumour along with accurate localization of particular compartment of tumour and


correlation with cytohistopathology.
