Jan 23, 2025 · The tentorium cerebelli (plural: tentoria cerebellorum) is the second largest dural fold after the falx cerebri. It lies in the axial plane attached perpendicularly to the falx cerebri and divides the cranial cavity into supratentorial and infratentorial compartments 1. It has free and attached margins 2.

There is an acute subdural hematoma observed along the superior portion of the tentorium on the right, measuring up to 3.2 mm in depth. No intra-axial collection, mass or focal abnormality identified. Ventricles and remainder basal cisterns are unremarkable.

Patient referred for evaluation of a posterior fossa lesion seen on the previous CT (not available). There is a solid lesion on the right superior aspect of the posterior fossa keeping a broad base within the tentorium cerebelli, but also with a doubtful invasion of the adjacent cerebellar folia on the multiplanar reformatted images.

Oct 30, 2023 · The tentorium cerebelli is the second-largest dural reflection that extends over the posterior cranial fossa. It separates the occipital and temporal lobes of the cerebrum from the underlying cerebellum and brainstem, and divides the cranial cavity into supratentorial and infratentorial spaces.

Jun 16, 2017 · Although there is no consensus on direct management of ITH, it is important to raise awareness of ITH as being potentially symptomatic. ITH can be easily detected on MRI or CT, as the tentorium is visible on 99% of contrast-enhanced cerebral CT studies 5 and virtually 100% of brain MRI examinations.

In this paper, we present an automatic, landmark-free 3D multimodal registration of pre-operative MRI to 4D US (high-refresh-rate 3D-US) for enabling guidance in knee arthroscopy. We focus on the...

The tentorium cerebelli is an integral part of the reciprocal tension membranes that divide some brain areas: the falx cerebri, the falx cerebelli, and the diaphragma sellae. The article discussed the anatomy of the tentorium cerebelli, the dura mater, and the ligaments and cervical muscles connected to the tentorium.

Mar 24, 2020 · MRI of brain in axial plane MRI of brain T1 post gadolinium . MRI findings: There is well defined avidly enhancing extraaxial mass with dural tail seen at left posterior fossae. It measures 3.3×3.1×3.5cm (WxAPxCC). This mass causing elevation of the left tentorium cerebellar and in close contact with the left tentorial cerebelli.

In this paper, we present a fully automatic falx and tentorium segmentation algorithm that uses a subject’s T1-w MRI. Instead of finding the falx directly, we consider the gray matter (GM) labels near the falx and tentorium.

This paper describes a feasibility study of a method for delineating the tentorium cerebelli in MRI brain scans. The tentorium cerebelli is a thin sheet of dura matter covering the cerebellum and separating it from the posterior part of the temporal lobe and …
