There was no satellite nodule
or palpable regional lymph node and systemic examination was within normal limit.
One of the 5 nodules, 23 x 19 mm in size, was hypoechoic and had a satellite nodule
Two other satellite nodules
with similar characteristics were observed, one at the superior pole of the lesion and another at the inferior pole of the lesion, measuring 4 mm and 3.8 mm respectively.
Inflammatory appearance of the skin, satellite nodules
, and fixed lymphadenopathies in the left axilla were observed.
On examination there was a large, fixed spherical mass on the left parietal-posterior scalp with central ulceration and multiple subcutaneous satellite nodules
abutting the left pinna.
From another point of view, cavities of the MDR group mostly appear as cavitary consolidation while in the NTM group as cavities with satellite nodules
, with significant difference between these two groups (Fig.
In addition, a linear margin, satellite nodules
, bronchial wall thickening, consolidation, and ground-glass attenuation were significantly more frequent in benign cavitary lesions than in malignant ones.
For purposes of staging, satellite nodules
, multifocal primary cholangiocarcinomas, and intrahepatic metastases are not distinguished and are considered multiple tumors.
Limb-sparing surgery can be performed where a tumour can be excised with a surrounding wide margin of tissue that contains microscopic 'satellite nodules
', which would lead to tumour recurrence if not removed.
Multiple satellite nodules
occur in 10 to 15% of all cases.
Tuberculomas commonly appear as smooth maginated round nodules on CT with calcification, cavitation and satellite nodules
The tumor may be diffusely infiltrative with indistinct borders, and small satellite nodules
can also be present. Microscopic examination reveals malignant cells invading liver parenchyma and vasoformative areas with vessels lined by malignant endothelial cells.
