Intraoperatively, a lobulated
cystic mass was seen replacing the whole left kidney.
Chest computed tomography (CT) scans revealed well-marginated and lobulated
bilateral paravertebral masses in the lower half of the thorax, with heterogeneous density owing to areas of fat and soft-tissue attenuation, suggesting long-standing disease (Fig.
Echocardiography revealed a very large lobulated
heterogenous mass in the right ventricular apex.
Microscopic examination (Figure, A) showed a vaguely lobulated
, well-circumscribed lesion, with a thick fibrotic margin but no true capsule.
They are usually round or ovoid in shape with a smooth or gently lobulated
None of the criteria necessary to call a mass a simple benign cyst were present, plus the mass had an irregular and lobulated
border (Figure 4), characteristics of malignancy.
2-cm soft tissue density in 1 of these cavities was also identified.
Computed tomography (CT) and magnetic resonance imaging (MRI) showed a characteristic lobulated
meningioma at the apex of the left petrous temporal bone and adjacent skull base.
The excised lobulated
tumor had the consistency of soft tissue, weighed 200 g, and measured 9.
6) Zaidi and Fathaddin reported a well-demarcated lobulated
mass with similar magnetic resonance imaging signal intensity as seminomatous tumours.
Targeted ultrasound confirmed the presence of multiple lobulated
and irregular solid hypoechoic vascular sub-centimeter masses that correlated with the mammographic and palpable findings (Figure 2).
Microscopically, these tumors are partially lobulated
, containing small, round cells with vesicular nuclei and minute nucleoli, arranged in cords within a fibromyxoid matrix.
