Triple falx cerebelli associated with two aberrant venous sinuses in the floor of posterior cranial fossa.
During regular dissection classes, we came across tripled falx cerebelli in a male cadaver. The main (middle) falx cerebelli was large and was attached to the internal occipital crest. It contained the occipital sinus. There were two smaller folds (right and left), one on either side of the falx cerebelli. There were two aberrant venous sinuses; each one connecting the ipsilateral sigmoid and t...
متن کاملA complex dural-venous variation in the posterior cranial fossa: a triplicate falx cerebelli and an aberrant venous sinus.
Variations of the dural folds and the dural venous sinuses are seldom reported in the extant medical literature. Such variations in the posterior cranial fossa may be problematic in various diagnostic and operative procedures of this region. We report our observation of an extremely rare variation of the falx cerebelli and posterior cranial fossa venous sinuses encountered upon dissection of a ...
متن کاملDural-Based Cavernoma of the Posterior Cranial Fossa Mimicking a Meningioma: A Case Report
Cavernous angiomas usually occur in the parenchyma of both the supra and infratentorial compartments. At times, they can both clinically and radiologically mimic other dural-based lesions. We present a case of a patient with chronic occipital headaches, initially thought to have a meningioma, but proven to be a cavernoma with histological analysis.
متن کاملBony wall damage in the region of the middle and posterior cranial fossa observed during otosurgery
BACKGROUND Bony wall damages in the region of the middle and posterior cranial fossa are usually observed in cases of chronic otitis media. These defects can also be congenital, post-traumatic, iatrogenic or due to tumors. They can potentially lead to the development of intracranial complications. MATERIAL/METHODS We analyzed patients who were diagnosed as having bony wall damage in the regio...
