Nidus is the weak spot, due to abrupt transition from arterial to the venous system, from high to low pressure vessels, and may result in hemorrhage,
perifocal edema and/or subsequent irritation of the surrounding brain tissue [2, 3].
MSCT of the head showed signs of hydrocephalus with
perifocal edema around the ventricles.
Cladosporium mostly cause ring enhancing lesion with
perifocal oedema in most of cases.
3 cm in size in the left frontal region with
perifocal edema compressing the frontal horn of bilateral ventricles with a midline shift to the right side.
SLIs were defined as focal lesions (3-15 mm in diameter), accompanied by hypointensity on T1 image, corresponding hyperintensity on T2 image, and hypointensity with
perifocal high signal on T2 FLAIR image [19].
The superior border of the mass showed distinctive,
perifocal fat stranding.
Thus, the MRI results showed a focal lytic well-defined soft-tissue lesion that was seen in the lower femoral epiphysis with thin sclerotic margins and
perifocal edema, most likely being a chondroblastoma [Figure 2].
A contrast-enhanced cranial computed tomography (CT) scan showed 2 lesions (3-4-mm) with rim enhancement and
perifocal edema at the right occipital and left parietooccipital lobes.
Por su parte, los cambios en la resonancia magnetica (RMN) cerebral ocurren tempranamente, y esta tecnica diagnostica ofrece una mejor visualizacion de las lesiones desmielinizantes, las cuales, caracteristicamente corresponden a areas parcheadas con aumento de la intensidad de la senal en T2 y FLAIR, sin efecto de masa, pero con edema
perifocal importante.
1x2cms,
perifocal fat stranding and multiple matted small bowel loops fixed posteriorly in presacral space and infiltrated by rectal mass and multiple necrotic lymph nodes in the abdomen.
As a rule there was a zone of
perifocal accumulation of serous or serous fibrinous exudates.
Normalization of skin integuments, foot warming,
perifocal inflammation arrest and demarcation as well as boundary epithelialization, secondary wound cleansing and active granulations were among the manifestations of distinct positive dynamics in wound process to make mention of.
