Contrast-enhanced CT demonstrated the presence of a well-circumscribed,
lobulated enhancing mass within the superficial right parotid gland.
Histopathology report showed anaplastic oligoastrocytoma: The classical appearance of oligoastrocytoma is that of a round to oval, water-clear cytoplasm ringing about round to
lobulated nuclei.
Abdominal computed tomography with intravenous contrast (axial view) showing a partially collapsed cystic lesion (white arrow) with a diameter of 11 cm at its widest portion, losing its normal spherical shape, having a
lobulated margin, and containing a number of septations (red arrows) within
The common myopathological changes consist of muscular changes such as muscle necrosis and regeneration, as well as interstitial proliferation and abundant
lobulated fibers.
Computerized tomography of the abdomen and pelvis demonstrated a huge,
lobulated mass arising in the anus and extending upwards along the rectum with a
lobulated contour.
A sphincterotomy was performed, and a part of a reddish,
lobulated polyp (10 mm) with insignificant hemobilia was extracted using Dormia basket (Figure 1).
The surface of the nodule was
lobulated with a few crusted erosions.
Computed tomography (CT) showed a
lobulated osteolytic lesion with well-defined margins, internal trabeculae, and surrounding sclerosis [Figure 3a].
The tumor had a non-encapsulated, still well-defined,
lobulated feature.
The diagnostic clue of the lesion is "histological examination showed well-circumscribed
lobulated mass (Figure 3) of cartilaginous tissue with no cellular atypia, necrosis, or vascular invasion.
On exam, the left inframammary area was noted to have a 1.5-cm, firm, exophytic,
lobulated, pink to skin-colored nodule with a surrounding hyperpigmented patch (Figure 1).
MRI showed a homogeneously
lobulated, hyperintense lesion with multiple fluid-fluid levels confirming the recurrence (Figures 5 and 6).
