The stone is prolate, obovoid in lateral view with a keel in the plane of bisymmetry and is essentially unilocular
although a collapsed second locule is visible in cross section (Fig.
On CT, pseudocysts are usually unilocular
round or oval fluid collections surrounded by a wall of variable thickness (Figure 8).
A drainage catheter placement whether by image-guided percutaneous route or surgically is necessary to convert the gastric leakage content to a controlled fistula.7,8 In the present case, because of an isolated unilocular
pyogenic liver abscess without a staple line leak, percutaneous drainage catheter placement with antibiotic therapy was sufficient.
* low risk (65%): unilocular
, simple septate, no flow on color Doppler
In the present study, we found 251 (55.9%) of PAT presented with multilocular type, 182 (40.5%) with unilocular
type and 16 (3.5%) with trabecular appearance.
Imaging studies (orthopantomographs) usually show a unilocular
radiolucency surrounding the crown of the affected tooth (figure 1), with a well-defined sclerotic border.
It has been observed radiographically that relapsing lesions are unilocular
or multilocular; the patient showed a unilocular
radiolucent area at four months of the first surgery, coronal to the erupting dental organ 33 [5,11].
About 70% of AOTs were identified as follicular, which is associated with an impacted permanent or supernumerary tooth; radiographic examination showed a well-circumscribed, unilocular
radiolucent lesion which is diagnosed earlier in life than extrafollicular type (mean age of 17 years) [6-8].
Radiological examination of orthopantomogram showed the presence of unilocular
radiolucencies extending from the last erupted molar to retromolar region (Figure 2).
Radiographically, these lesions are usually an unilocular
, well-defined radiolucency, although the lesion occasionally may appear multilocular.
Although, the cyst is unilocular
and filled with clear fluid, the malignant cyst cannot be excluded.
En la evaluacion radiografica, la variante denominada folicular intraosea del TOA, muestra un entorno radiolucido unilocular
bien delineado asociado a la corona de un diente retenido.
