Caption: Figure 6: Anatomical drawing of persistent fetal lobulations
Suspicious: enlarged lymph nodes with asymmetric cortical thickening, cortical lobulations
, sharply demarcated borders (Figures 4 and 5).
4.) The remaining areas of lobulation
appeared as an indeterminate plateau perfusion pattern, or Type II curve.
(8) Hawkins et al further reported that other factors associated with an increased risk of recurrence are (1) young age, (2) involvement of the skin by the cyst, (3) lobulation
of the cyst, (4) rupture of the cyst, and (5) failure to adhere to Sistrunk's second recommendation.
Data included age, aneurysm site, aspect ratio, whether there were multiple aneurysms or daughter sacs present, lobulation
, and hemodynamics.
These tumors typically appear to be well circumscribed and often exhibit coarse lobulation
on cut section, simulating the lobular character of the normal human pancreas.
evaluated the radiological features of the malignant nerve sheath tumors and reported peritumoral edema, intratumoral lobulation
, and peripheral enhancement are suggestive of malignancy.
(4,5) This anomaly was reported to be observed in 3-5% of patients with congenital heart diseases and it was also reported to be accompanied with bi-lobed or symmetric liver, intestines and mesenteric mal-rotation, reversed pulmonary lobulation
, spleen agenesis or multiple spleens, and anomalies particularly with larger vascular bodies.
GIST has distorted shape, lobulation
, irregular borders and increased echogenicity in comparison with the surrounding muscle echo, inhomogeneous pattern (inhomogeneity, hyperechoic posts, anechoic area), marginal halo and extraluminal growth pattern.
The morphological features were named as lobulation
index (LI), elliptic-normalized skeleton (ENS), elliptic-normalized circumference (ENC), depth to width ratio (D: W), long axis to short axis (L: S), number of substantial protuberances and depressions (NSPD), and the size of lesion.
is an important category of CT imaging signs, which is dependent on the ingrowth of connective tissue septa containing fibroblasts derived from perithymic mesenchyme .
The diagnosis becomes challenging when the solitary pulmonary lesion shares some radiological features with primary lung cancer, such as border irregularity, lobulation
, and spiculation.
