Variant anatomy of superior cerebellar artery and associated clinical implications
Journal Title: International Journal of Anatomical Variations - Year 2018, Vol 11, Issue 3
Abstract
Superior cerebellar arteries originate from basilar artery just before terminating into posterior cerebral arteries. These arteries travel below the 3rd and above the 4th cranial nerves. Superior cerebellar arteries (SCA) irrigates superior surface of cerebellum and superior vermis. The knowledge of variations in the branching pattern of SCA is essential to neuro-radiologists and neurosurgeons in comprehending vascular malformations, SCA syndrome, handling of lesions of the basilar termination and explaining trigeminal neuralgia. The variations are also valuable to avoid inadvertent ligation or sectioning of these arteries during surgical approaches to the posterior cranial fossa lesions. Due to afore mentioned immense clinical implications of these arteries, review of literature has been explored. The study will provide ready and consolidated information for radiologists for interpretation of imagery and neurologists for diagnosing and treating lesions around the superior cerebellar arteries

Variations of hepatic circulation in two human cadavers with clinical implications
Two rare variations of hepatic vasculature were discovered during routine anatomical dissection in the gross anatomy laboratory at Rush University. The first case is that of an 82-year-old female with the left hepatic ar...
Absence of right posterior communicating artery
The circle of Willis represents a vascular network located at the base of the skull in the interpeduncular fossa. The anterior cerebral artery forms the anterior section of the circle of Willis from the right and left si...
Unilateral duplex ureter
A routine cadaveric dissection of a 77 year old female with metastatic breast cancer demonstrated an ectopic unilateral left duplex ureter. The duplicated ureters originated separately at the renal pelvis, communicating...
Persistent metopic suture with multiple sutural bones at unusual sites
Sutural bones are small irregular bones found in the sutures and fontanels of the human skull. They are commonly found at lambda and lambdoid suture followed by pterion; and rarely at other sites. They vary from person t...
