Resumen

DIAZ GALARZA, Yenys et al. Correlation between clinical, imaging, histological and pathological aspects in the diagnosis of spinal extramedular tumors and pseudotumors. MEDISAN [online]. 2022, vol.26, n.6  Epub 22-Dic-2022. ISSN 1029-3019.

Introduction:

The intradural extraspinal tumors are morbidity and mortality cause. To identify and analyze them, the magnetic resonance is the imaging diagnostic means of election.

Objective:

To characterize patients with intradural extramedular spinal tumors and pseudotumors according to clinical, imaging (by magnetic resonance) histological and pathological variables.

Methods:

An observational, descriptive, longitudinal and prospective study was carried out in 20 patients with suspicious clinical diagnosis of intradural extraspinal tumor or pseudotumor or not, confirmed by means of magnetic resonance who were assisted in the Imaging Department of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba from January, 2014 to the same month in 2017, coming from the general hospitals of this province and Guantánamo.

Results:

There was a higher frequency of the male sex (70.0 %), mainly 60 and more years (30.0 %), as well as of the vertebral pain (100.0 %) and disorders of the muscle stretch reflex (65.0 %) as symptoms and signs of the neoplasm processes. According to the intensity of the signs captured in the magnetic resonance, the isointense tumors prevailed in the sequence T1 (70,0 %) and the hyperintense and isointense in the sequence T2 (35.0 % in each one), mainly of dorsal localization (60.0 %). Also, the most common supicious clinical diagnosis was that of compressive myelopathy (25.0 %), as long as, among the imaging, histological and pathological diagnosis the metastasis and meningiomas were notable.

Conclusions:

The magnetic resonance offers an approach to the definitive diagnosis of these tumors, which is corroborated by means of the histological and pathological study.
