Clival masses Radiology Reference Article Radiopaedia

An important normal variant that can sometimes be mistaken for clival pathology is a prominent basilar venous plexus that can appear to erode the posterior surface of the clivus 4, as well as prominent clival diploic veins that may mimic masses of the body of the clivus 5. Intracranial compartment growing into clivus. invasive pituitary macroadenom Clival tumors are rare tumors that arise in the clivus, a portion of bone at the base of the skull between the occipital and sphenoid bones. This area is surrounded by essential structures and nerves of the brainstem and important arteries, such as the internal carotid arteries. Clival tumors can affect the function of all these systems, leading to. Chordome sind histologisch gutartige Tumoren, die aus Resten der Chorda dorsalis entstehen. Am häufigsten treten sie im Bereich des Steißbeines und des Clivus (Schädelbasis) auf. Obwohl sie histologisch gutartig sind (WHO Grad I), haben sie ein sehr aggressives infiltrierendes Wachstum, so dass sie trotz kompletter Tumorentfernung zur Rezidiven neigen. Auch wenn die Chordome zunächst außerhalb der Hirnhaut entstehen, wachsen sie häufig nach intradural und führen zur Kompression von. Tumoren mit Ausdehnung im Bereich von Sella turcica und Clivus betreffen sowohl das neurochirurgische als auch HNO-ärztliche Fachgebiet. Tumoren dieser Region können sich nach intrakraniell als auch in Richtung Nasen-Rachen-Raum ausdehnen. Klassisches Beispiel hierfür sind die Clivuschordome. Sie können sowohl als weitgehend intrakranielle Tumoren in Erscheinung treten, bei ventraler Ausdehnung dagegen auch einen nasopharyngealen Tumor imitieren. Frontobasale Karzinome oder die von der.

Als Clivus bezeichnet man die nach dorsal abfallende knöcherne Struktur, die die mittlere von der hinteren Schädelgrube trennt. 2 Anatomie Der Clivus wird unterteilt in den Clivus ossis occipitalis , der von der Pars basilaris des Os occipitale gebildet wird und den Clivus ossis sphenoidalis , der Teil des Corpus des Os sphenoidale ist intracranial tumors in adults. Meningiomas are more frequent in women and their incidence increases with age. Intracranially meningiomas can be classified according place of origin and cellular type. The clivus is covered with dura mater, therefore it can be affected. Meningiomas at the center of the clivus proper are very uncommon.

  1. Bei entsprechender Größe führen diese Tumore nicht nur zum Hörausfall und zu Gleichgewichtsstörungen, sondern auch zur Mitschädigung des Gesichtsmuskelnervs (Nervus facialis) und zur Hirnstammkompression. Durch eine operative Resektion kann, im Gegensatz zur Bestrahlung, der raumfordernde Effekt des Tumors, insbesondere auf den Hirnstamm, sofort entlastet werden
  2. Chordome sind langsam und destruktiv wachsende Tumore der Wirbelsäule und der Schädelbasis, die in etwa 10 % der Fälle metastasieren. Chordome werden manchmal zu den Knochentumoren gezählt, obwohl sie nicht aus Knochengewebe stammen, sondern aus Resten der Chorda dorsalis an den Enden der Wirbelsäule. Damit lassen sich auch ihre Hauptlokalisationen, nämlich Schädelbasis und Steißbein, erklären. Die ICD-O-3 klassifiziert sie unter die Sonstigen Tumoren des Nervensystems

  4. Chordomas can arise from bone in the skull base and anywhere along the spine. The two most common locations are cranially at the clivus and in the sacrum at the bottom of the spine
  5. The clivus is located behind the sphenoid sinus and provides support for the part of the brain known as the pons. Cancers that affect the clivus are typically seen clearly on medical imaging scans. One issue in this area is a rare tumor known as a chordoma
  6. Der Tumor grenzt sich in der Regel gut von den benachbarten Hirnstrukturen ab und wächst nicht in andere Gewebe ein. Er kann flächig oder knotig wachsen und manchmal verkalken. Oft ist der Schädelknochen über dem Tumor verdickt. In über 90 Prozent der Fälle wächst ein Meningeom im Schädel (intrakraniell)

  3. When the tumor location or extension is too lateral or inferior to be effectively resected with an endoscopic approach, an open approach or a combination of endoscopic and open approaches in stages should be considered. Postoperative RT is usually indicated because the likelihood of recurrence is high in spite of complete surgical resection. The main site of recurrence is local and late.
  4. How much of the tumor was taken out during surgery; If you want information on your prognosis, it is important to talk to your doctor. NCI also has resources to help you understand cancer prognosis. Doctors estimate chordoma survival rates by how groups of people with chordoma have done in the past. Because there are so few people with chordoma, these rates may not be very accurate. They also.

Tumors that arise purely from the clivus are rare, but this region can be involved with numerous processes extending from the structures near the clivus, mainly from the petrous-clival line. Tumors may be limited to a part of the clivus, or they may involve the entire clivus; they may also extend superiorly to the suprasellar region, inferiorly to the foramen magnum and cervical spine, and. The topographic anatomy of the clivus makes several surgical approaches feasible. 1,11,34,35,37,41,75,76 The choice of an approach to remove a tumor from this region must take into account the nature and location of the lesion (i.e., whether the lesion is intradural or extradural, its position in respect to the clivus, and its lateral extension)

The tumor tissue was isointense on T1-weighted imaging (WI), T2WI and fluid-attenuated inversion recovery, and moderate homogenous enhancement was identified on the post contrast scan . Due to the symptoms of the present illness and MRI imaging, chordoma and malignant tumor in clivus could not be excluded Calcifying fibrous tumor is a benign fibrous tumor. It rarely occurs in the clivus. The present study describes a case of a 56-year-old female, who was admitted to Taihe Hospital with dizziness not accompanied with headache for 2 months. Brain computed tomography examination revealed a well-defined, partially calcified lytic-expansile lesion in the clivus, which corresponded to an enhancing.

Petroclival meningioma arises in the upper two thirds of the clivus at the petroclival junction medial to the fifth cranial nerve. These tumors displace the brain stem and the basilar artery to the opposite side. Petroclival meningiomas are surgically challenging tumors due to the proximity to cranial nerves, major blood vessels, and the brainstem with considerably high.

Tumors of the lower clivus down to the foramen magnum are best approached by the far-lateral approach or combination approaches. Surgical Approaches. Because petroclival meningiomas occupy difficult locations, a number of surgical approaches have been proposed for their removal. [1,5,9,11,14,16,21,23,25] Understanding these lesions and their surgical anatomy and realizing the need to maximize. Clivus is a unique central area of the skull base. Many tumors either arise from or invade this region. Neuroimaging plays a central role in characterizing and delineating the extent and the origin of these tumors. Before approaching clival tumors, we will first review the clival anatomy in relation to the surrounding structures. This is really.

Chordoma tumor cells originate from the notochord, an important structure that exists in the neuraxis (axis of the central nervous system) of embryos but disappears before birth. Sometimes notochord cells can remain behind after birth; in patients with chordoma, these cells become abnormal and begin multiplying to form a tumor Tumors of the clivus are extremely rare. The clival chordoma and chondrosarcoma are the most common of these tumors; however, these each represent only 0.1 to 0.2% of all intracranial tumors. 1,2 Metastatic lesions of the clivus occupy an even smaller subset of these tumors, with no more than 34 cases previously reported in the literature. 3 Given the scarcity of metastatic clival lesions. The tumor invaded the clivus and both petrous apices. It was radically but partially resected through a transsphenoidal approach. Following surgery, the patient showed symptomatic improvement.

  1. Chordomas occur in the midline along the spinal axis from the clivus to the sacrum, anterior to the spinal cord. Chordomas are distributed as follows: 50% sacral, 35% skull base, and 15% in the vertebral bodies of the mobile spine (most commonly the C2 vertebrae, followed by the lumbar spine and then the thoracic spine).

Computerized tomography-guided transnasal stereotactic tissue diagnosis of a lytic lesion in the clivus was performed successfully using the Cosman.
  2. INTRODUCTION. Clivus meningiomas in particular have until recently been uniformly lethal. The outlook for such patients must be improved by achieving an earlier and more accurate diagnosis, by improving surgical techniques, and by developing a better understanding the pathological anatomy. 1 Posterior fossa meningiomas account for only 10% to 15% of intracranial meningiomas, and petroclival.
  3. It extended along the clivus, and into the ethmoid sinuses. Chordoma is a rare slow growing tumor type, and UM-Chor1 is a relatively slow growing cell line. The cells express the transcription factor T (Brachyury) that is the most specific marker for chordoma. This cell line was accessioned with the support of the Chordoma Foundation, a nonprofit organization working to improve the lives of.

Chordoma and chondrosarcoma of the skull base are rare tumors. The combined incidence is reported to be 0.03 per 100,000 persons in the U.S. 1 Occupying the same anatomic location, the clinical presentation and radiologic characteristics of chordoma and chondrosarcoma are quite similar, often resulting in their amalgamation in the literature. They are, however, quite different entities. For example, in our case, the tumor was initially thought to be a meningioma. In the absence of symptoms or signs of infection such as fever, the clinical manifestations varied based on the locations. For our patients, the lesion was located in the middle of the upper clivus area. Based on the symptoms and MRI manifestation, a meningioma was.

of these tumors to many critical soft-tissue structures. At CT, intracra- nial chordoma typically appears as a centrally located, well-circum-scribed, expansile soft-tissue mass that arises from the clivus with asso-ciated extensive lytic bone destruction. However, MR imaging is the single best imaging modality for both pre- and posttreatment evalua-tion of intracranial chordoma. On T1. Clivus: Deep within the head lies the floor of the cranial cavity, which contains the brain. The bone in the central portion of this cranial floor is known as the clivus. Access to this region is often obtained through the nasal cavity and sinuses, thus avoiding external scarring. Common tumors in this region are chordoma, chondrosarcoma and meningioma. Foramen Mangum: At the base of the skull. a patient who developed the primary tumor at age of 8 years, were investigated by cytogenetic and the fluorescence in situ hybridization (FISH) approach. Of the patient's 3 daughters, 2 developed, respectively, a clivus chordoma and an astrocy-toma in infancy, a familial aggregation highly suggestive of a genetic background. After a 31-year hiatus, 2 tumor recur-rences, developed over 17. These tumors are generally very slow-growing and may be present for a long time before causing any symptoms. They are made up of cartilage or cartilage-like cells, can grow to a large size, and may occur as a single or as multiple tumors. The malignant (cancerous) form of chondroma is chondrosarcoma. There are several different types of chondrosarcoma, including conventional, clear cell. Doch am Ende soll es nicht der Tumor sein, der ihm zum Verhängnis wird. Causa obscura: Tod ohne Tumor.

These tumors are considered malignant and may metastasize, though they typically grow slowly. Even slow-growing chordomas can become aggressive and grow quite large locally, putting pressure on or invading into critical parts of the brain or spine, which may cause pain and nerve problems or even be life threatening. What are the symptoms of chordoma? Chordomas can press on the spine, brain and.
