Left portal branch has a longer extraparenchymal
course and tends to be slightly more horizontal than the right branch.
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 .
On radiology, chest X-ray showed two opacities, round to oval, likely to be extraparenchymal
in nature, suggestive of metastasis was given.
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
Bandres JC, White AC Jr, Samo T, et al: Extraparenchymal
neurocysticercosis: report of five cases and review of management.
The mass was intradural and extraparenchymal
having a thick walled cyst.
3 (4) 0 Mixed 8 (11) 0 Lesion stage Cystic only 22 (31) 1 (7) 0.
CT finding that can be identified as early as 90 minutes (6,7) after symptom onset is the "hyperdense vessel sign" (Figure 3), which is usually seen in the proximal (M1 segment) MCA, but can be seen in any arterial structure.
Patients with active parenchymal or extraparenchymal
disease defined by the neuroradiographic appearance of the lesions can be treated with albendazole, 15 mg/kg/day, divided into 2 daily doses for 8 days.
disease, such as ventricular, spinal, and subarachnoid involvement, has a poorer prognosis.
Additional sequence like 3D CISS was acquired for extraparenchymal
cystic lesions including both extra-axial and intraventricular group whenever required.
