Extent of Invasion.--Macroscopic
extraparenchymal extension is the parameter required to upstage a tumor to T3 and is thus more important than microscopic
extraparenchymal extension.
In the analysis results, delayed enhancement was observed at the
extraparenchymal subarachnoid space (foramen magnum, pontine cistern, Sylvian fissure) in patients with INPH.
Acerca de la irrigacion portal del higado, Standring (2008) escribio: "The left portal vein has a longer
extraparenchymal course (4-5 cm) and tends to lie slightly more horizontally than the right portal vein, but is often of smaller caliber.
Left portal branch has a longer
extraparenchymal course and tends to be slightly more horizontal than the right branch.
The contraction strength of the intracranial vessels, both intra- and
extraparenchymal ones, can usually be evaluated through an angiography or through an angiomagnetic resonance imaging (Angio-MRI); however, transcranial Doppler (TCD) ultrasounds are more rapid and less invasive [10].
Therefore, cases of NCC in vesicular stage, colloid stage, and granular nodular stage, either parenchymal or
extraparenchymal, were finally included.
Coronary arteries are most frequently affected, but the process may occur in other
extraparenchymal muscular arteries such as celiac, mesenteric, femoral, iliac, renal, axillary and brachial artery [6].
On radiology, chest X-ray showed two opacities, round to oval, likely to be
extraparenchymal in nature, suggestive of metastasis was given.
This creates a mobile segment between the two fixed segments (
extraparenchymal and intraparenchymal) of the lenticulostriate arteries which is vulnerable to stretching and injury during head trauma.
The tumor infiltrated the surrounding parotid gland, but no
extraparenchymal extension was seen.
Elkin and Bernstein classified renal cysts; (1) renal cysts due to dysplasia of the kidney; (2) polycystic disease; (3) cortical cysts; (4) medullary cysts; (5) miscellaneous intrarenal cysts; (6)
extraparenchymal renal cysts.
