ABSTRACT
Neonatal cerebral infarction is a serious and disabling condition. It is extremely rare if it occurs in association with portal vein thrombosis. We are reporting 2 cases of neonatal cerebral infarction with this etiology. The unique mechanism of cerebral infarction will be discussed. We propose that in the absence of any identifiable cause for the cerebral infarction, portal vein thrombosis should be considered and a Doppler sonography for the portal system is worth carrying out to confirm the diagnosis

Intravenous digital subtraction angiography [IVDSA] was performed in 5 patients with renal cell carcinoma presenting with a solitary renal mass to assist in the preoperative evaluation to document the number of renal arteries present with the relative vascularity of the tumour, and to record tumour extension into the renal vein or inferior vena cava. The IDVSA findings were compared with computed tomography [CT] as well as the surgical and pathological results. IVDSA was found to be relatively non-invasive, safe and accurate. It offers unique information and is complementary to CT in the evaluation of a renal mass
