(17) found a predominance of spiculated
margins in women with breast cancer aged <40 years.

Caption: Figure 3: Axial noncontrast CT image in the lung window (a) demonstrates a spiculated
mass with an area of central cavitation in the right upper lobe abutting the mediastinum (solid arrow) with imaging features suggesting a primary pulmonary squamous cell carcinoma.
On mammogram, a 15 mm diameter hyperdense lesion was observed in the upper external quadrant of the left breast with a spiculated
prethyroid muscles); spiculated
or microlobulated margins; microcalcifications; taller-than-wide shape; evidence of extrathyroidal growth or pathologic adenopathy." When a FNA was obtained, the report for the cytopathologist included the US risk categorization of the nodule.
In contrast, with [N.sub.2] APPJ treatment, RBCs became spiculated
with plasma exposure time.
Bruce, "Digital mammogram spiculated
mass detection and spicule segmentation using level sets," in
Poikilocytes may be categorized as spiculated
A contrast enhanced computed tomography (CT) of the thorax and neck was done which showed the presence of a small, moderately enhancing nodular lesion (21 x 20 mm) with spiculated
margin in the apical segment of right upper lobe along with surrounding emphysematous bullae (figure 3).
A thin-slice CT of the lung reveals that the 13-mm solid nodule in the right upper lobe has spiculated
As the foci of tumor cells in PTC is not clearly separated from the surrounding thyroid tissues, with common interstitial infiltration in the surrounding thyroid parenchyma, [sup] the margin is unclear, and the edge shows spiculated
infiltration by ultrasonography.
ii)Metastatic nodules: classic imaging features of metastatic nodules is a long list.Main features seen in our patients were positive feeding vessel sign, subpleural location, lobular spiculated
margins and interval size and number progress.iii)Nodules with Equivocal features.
