What does the suprasellar cistern do?
The suprasellar cistern is a cerebrospinal fluid filled space between the top of the pituitary and bottom of the hypothalamus. The pituitary stalk normally courses through this space to enter the pituitary gland and is critical for the normal operation of the pituitary.
What does the suprasellar cistern contain?
The suprasellar cistern (also known as pentagon of basal cisterns) is a cerebrospinal-fluid filled space located above the sella turcica, under the hypothalamus. It contains the optic chiasm, the infundibulum and the circle of Willis.
Can you see herniation on CT?
Radiographic features. Uncal herniation can be suggested on CT, however, MRI is the gold standard. Features of unilateral descending tentorial herniation include: medial displacement of the uncus and parahippocampal gyrus of the temporal lobe.
Is a Suprasellar mass cancerous?
Almost all pituitary tumors are benign (not cancer) glandular tumors called pituitary adenomas. These tumors are called benign because they don’t spread to other parts of the body, like cancers can.
What is Suprasellar mass?
Suprasellar masses are neoplastic, vascular, congenital, or infectious/inflammatory in origin. Magnetic resonance imaging (MRI) is the study of choice for evaluating suprasellar masses, although computed tomography (CT) may provide complementary information.
What is cistern in biology?
A cisterna (plural: cisternae) are all of the membrane-bound sacs that could be found in both the Golgi apparatus and in the Endoplasmic Reticulum. Cisterna are an integral part of the packaging and modification processes of proteins occurring in the Golgi.
Can you see bulging disc on CT scan?
A computerized axial tomography scan (a CT or CAT scan) or a magnetic resonance imaging test (an MRI) both can show soft tissue of a bulging disc. These tests will show the stage and location of the herniated disc so you can receive proper treatment.
What are the basal subarachnoid cisterns?
The basal subarachnoid cisterns are expansions of the subarachnoid space and transmit cranial nerves and intracranial vessels. Providing neurosurgeons with key concepts, anatomical landmarks, and techniques can result in safer procedures and better patient outcomes.
What is a cistern in anatomy?
Cistern means “box” in Latin and structurall us characterized by an expansion of the subarachnoid space created by the separation of the archnoid and pia mater. The arachnoid membrane lines the inner surface of the dura mater. By contrast, the pia mater adheres to the central nervous system.
Where is the crural and ambient cistern located?
The crural cistern is located between the cerebral peduncle and posterior part of the uncus. The crural and ambient cisterns contain the P2 segment of the posterior cerebral artery and some of the P1 and P2 branches. (Images courtesy of AL Rhoton, Jr.)
What is a pontine cistern?
The pontine cistern, or prepontine cistern, is a CSF-filled subarachnoid cistern located ventral to the pons and dorsal to the clivus. It is contiguous with the pontocerebellar cisterns laterally, interpeduncular cistern superiorly, and premedullary cistern inferiorly. Likewise, people ask, what is Suprasellar cistern?
