Histologicamente el ameloblastoma unilocular
esta constituido por una capsula de tejido conectivo fibroso, denso, uniformemente engrosado, que rodea una sola luz grande llena de liquido con un revestimiento epitelial, de espesor uniforme y tiene una capa de celulas basales en empalizada con polarizacion inversa del nucleo; (13) concordando con el reporte histopalogico del caso, donde encontro un tejido de sosten fibroso, epitelio ameloblastico, con celulas hipercromicas en forma de palizada.
A more recent study of 134 women showed 160 benign ovarian cysts, 76% of which were unilocular
and the rest more complicated.
and honeycomb like cluster of multilocular cystic masses were noted within the peritoneal cavity, particularly around the liver causing scalloping of hepatic borders.
Typical CT findings for renal hydatidosis include a cyst with a thick or calcified wall, a unilocular
cyst with a detached membrane, a multiloculated cyst with mixed internal density and daughter cysts with lower density than the maternal matrix.
ZACD appears as radiolucency with well defined borders, while the multilocular type demonstrates numerous small cavities within, which resemble mastoid air cells.
Although the most frequently encountered form of renal cystic lesion is the unilocular
, simple renal cortical cyst, others can appear on imaging as solitary or multiple, complex cystic lesions, with variable likelihood of being malignant neoplasms.
There are no pathognomic radiological features of ameloblastoma, but radiographs may show a well-defined radiolucent lesion with scalloped margins which may be unilocular
or multilocular ('soap bubble' appearance).
They are typically unilocular
, anechoic, and thin-walled, with no papillae, and almost never malignant.
Radiologic evaluation of our patient demonstrated a 6-cm unilocular
, suprarenal mass without solid components or internal septation that did not change appreciably in size during the first year of life.
granulosis produces unilocular
cysts and is most prevalent in areas where livestock is raised in association with dogs.
Time and again, studies have indicated that lesions identified on ultrasound as unilocular
and under 5 cm have a very low risk of malignancy," Dr.
The positive predictive value was 9%, but that would have increased to 20% if patients with unilocular
cystic tumors smaller than 5 cm were followed with sonography every 3-6 months instead of undergoing surgery Dr.
