A 62 year old man worked up for carpal tunnel syndrome had imaging of his cervical spine that revealed an enhancing clival lesion, which extended into the left occipital condyle. Neelakantan A, Rana AK. Link, Google Scholar The clivus is a component of the central skull base. The buccal space, also known as the buccinator space, is one of the seven suprahyoid deep compartments of the head and neck.. The subarachnoid cisterns, or basal cisterns, are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: "box"). Chiari malformation (CM) is a structural defect in the cerebellum, characterized by a downward displacement of one or both cerebellar tonsils through the foramen magnum (the opening at the base of the skull). After gadolinium, homogeneous contrast enhancement was observed. Link, Google Scholar; 48 Spagnoli MV, Goldberg HI, Grossman RI et al.. Intracranial meningiomas: high-field MR imaging.

Cisterns may have vessels and/or cranial nerves the posterior angle which contains a sulcus that houses the inferior petrosal sinus medially, and the jugular notch of the occipital bone forms the jugular foramen laterally; the anterior angle whose medial half articulates with the spinous process of the sphenoid and lateral half fuses with the squamous part at the petrosquamous suture It is a transition zone b/w a mobile cranium & spinal column. Endoscopic endonasal biopsy was performed on the abnormality revealing a capillary hemangioma. An understanding of brain arterial vascular territories is important in understanding stroke and complications from surgery and endovascular procedures.. Gross anatomy They are larger than the third or fourth ventricles but can be asymmetrical. Synonyms: Clivus-canal angle, craniovertebral angle Reference Munk PL, Ryan AG. The facial nerve is the seventh (CN VII) cranial nerve and comprises two roots, a motor root and a smaller mixed sensory, taste and parasympathetic root, known as nervus intermedius, which join together within the temporal bone (TA: nervus facialis or nervus cranialis VII).. Interpreting findings seen at CT of the neck is challenging owing to the complex and nuanced anatomy of the neck, which contains multiple organ systems in a relatively small area. The lesion was removed at endoscopic endonasal surgery; histologic and immunohistochemical findings proved it to be neurenteric cyst. In the first definition, familiar to most head and neck surgeons, the parapharyngeal space is divided into prestyloid and poststyloid (retrostyloid) compartments 1-3,10.In the second definition, introduced by some radiologists, the prestyloid parapharygeal space is simply termed the parapharyngeal space, Although one could be excused for thinking that within the brain, such a carefully organized organ, blood supply would be constant, the truth is that a great deal of variety exists. Within the internal acoustic meatus, the nerve branches into cochlear and vestibular nerves to supply the The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the brain.The MCA arises from the internal carotid artery as the larger of the two main terminal branches (the other being the anterior cerebral artery), coursing laterally into the lateral sulcus where it branches to perfuse the cerebral cortex.. In the emergency department setting, CT is performed to investigate acute infectious or inflammatory symptoms and chronic processes. Two naming conventions exist in the literature.

Each has five divisions, including three horns that project into the lobe after which they are named: anterior/frontal horn Articles. Teaching Atlas of Musculoskeletal Imaging. Here we report an unusual location of a clival intraosseous hemangioma. The Welcher basal angle can be measured on plain films or mid-sagittal CT or MRI images and is formed by the nasion-tuberculum and tuberculum basion lines . He was the Scientific Chair of the Annual Society of Interventional Radiology (SIR) meeting in 2010 and a recipient of the SIR innovator of the year award in 2015. As they are interconnected, their patency is essential for CSF circulation. Clin Radiol. 1.1 Basal/Clival Parameters. Anteriorly, there is often an accessory parotid gland, which may be separate from the main gland. Its primary function is as The trachea, known colloquially as the windpipe, connects the upper respiratory tract to the lungs via the tracheobronchial tree, enabling gas exchange. On CT scans, the lesion was Symptoms depend on the location and occur as a result of the tumor pressing on nearby tissue. [] The patient had complaints of headache and diplopia for 5 days. Some clival meningiomas are are not usually spotlighted during oral and maxillofacial radiology training. Gross anatomy The buccal spaces are paired fat-containing spaces on each side of the face forming cheeks.Each space is enveloped by the superficial (investing) layer of the deep cervical fascia.. The facial nerve has a complex and broad range of functions. In the emergency department setting, CT is performed to investigate acute infectious or inflammatory symptoms and chronic processes. J Neurosurg. Gross anatomy. The cerebellum, meaning "the little brain", sits at the base of the brain in the posterior cranial fossa below the tentorium and behind the brainstem. CMs can cause headaches, difficulty swallowing, vomiting, dizziness, neck pain, unsteady gait, poor hand coordination, numbness and tingling of the hands and feet, and The craniovertebral (CVJ) is a collective term that refers to the occiput (posterior skull base), atlas, axis, and supporting ligaments. Many cases never produce symptoms. Verstraete K. Clival Chordoma: A Rare Finding in Children. The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the brain.The MCA arises from the internal carotid artery as the larger of the two main terminal branches (the other being the anterior cerebral artery), coursing laterally into the lateral sulcus where it branches to perfuse the cerebral cortex.. The pons has a bulbous shape and has two main components - the basis pontis (basal/ventral part) and the pontine tegmentum (dorsal part).. When clival signal intensity was judged by using the grading system (compared with the signal intensity of WM, GM, or fat), accuracy was much lower and ranged from 5881%. The vestibulocochlear nerve is the eighth (CN VIII) cranial nerve (TA: nervus vestibulocochlearis or nervus cranialis VIII).It exits the brainstem through the cerebellopontine angle, passing into the internal acoustic meatus as part of the acousticofacial bundle. The tail is not distinct from the rest of the gland, but it has been defined as the inferior 2 cm of the gland 11. It is a modification to the angle of Landzert, which represents an angle between planum sphenoidale and the clivus. The finding of clival marrow hyperintensity relative to WM but hypointensity relative to fat was most sensitive (100%); however, this criterion had low specificity (43%).
