“…The fact that there are only a few studies in the literature relating the tumour with radiological findings may complicate or confuse the investigative process [3].Regarding biological markers, there was no study of metabolites in this patient, once their usage is questionable in the literature. The VMA can be defined as a tumour marker since its urinary levels decrease after tumour resection [13]; however, it is not essential to define conducts, because even though the disease is present, the urinary analysis can be negative [14,15]. No molecular tests were performed on the tumour tissue sample, except for immunohistochemical markers.…”
