Question:305
 
Correct Answer: C
Explanation:
Inguinal-scrotal ultrasound is indicated to confirm the diagnosis, it can identify abnormalities in the testis, complex cystic masses, tumors, appendages, spermatocele or associated hernia. Transillumination involves a light source shined through the scrotum causing the hydrocele to illuminate. The bowel may also illuminate. A positive transilluminescence should not stop the clinician from investigating other, more serious, causes or co-morbid conditions associated with secondary hydrocele and is not reliable for final diagnosis. Hydrocele aspiration has a high infection risk and the hydrocele usually returns and is threfeore no longer recommended

Isolated posterior cerebral artery (PCA) ischaemia presents with pure hemianopia, but as the PCA is a branch of the vertebrobasilar artery, hemianopia may be associated with brainstem symptoms in vertebrobasilar disease.
