Table 5 Sonographic appearance of intracranial tumors

From: Ultrasound-guided versus traditional surgical resection of supratentorial gliomas in a limited-resources neurosurgical setting

Case # Pathology (WHO grade) Gd contrast enhancement (intensity and distribution) US ability to localize tumor (well/poor) US ability to delineate tumor margins (well/moderate/poor) Echogenicity
1 GBM (IV) Strong with patchy non-enhancing Well Moderate Hyper/mixed*
2 PA (I) Strong patchy Well Well Hyper
3 Oligoastro (II) Faint patchy Well Poor Iso
4 GBM (IV) Faint Patchy Well Moderate Hyper/mixed
5 GBM (IV) Faint Patchy Well Well Hyper/mixed
6 PXA (II) Enhancing nodule with cyst Well Well Hyper with hypoechoic cyst
7 GBM (IV) Moderate heterogeneous Well Well Hyper/mixed
8 GBM (IV) Strong rim enhancement Well Well Hyper/mixed
9 GBM (IV) Strong with areas of necrosis Well Well Hyper/mixed
10 GBM (IV) Strong rim enhancement Well Well Hyperechoic borders, less hyperechoic core
11 GBM (IV) Rim enhancement Well Well Hyperechoic borders, less hyperechoic core
12 Diffuse Astrocytoma (II) Non enhancing Poor Poor Iso to hyper with homogenous texture
13 GBM (IV) Strong with areas of necrosis Well Moderate Hyper/Mixed
14 Diffuse Astrocytoma (II) Non enhancing Poor Poor Iso
15 Anaplastic PXA (III) Homogenous enhancement Well Well Hyper
16 Anaplastic Astrocytoma (III) Cyst with enhancing wall and a mural nodule Well Well Hyper (nodule)–Hypo (cyst)
17 GBM (IV) Thick ring enhancement Well Well Hyper/Mixed
  1. Mainly hyperechoic with areas of lower echogenicity within the core
