Surgery Significantly Improves Survival in Patients With Chordoma. However, ecchordosis physaliphora is usually in a clival location and does not enhance with gadolinium infused MRIs. Abstract. Tuesday, February 15, 2011 Ecchordosis physaliphora. Ecchordosis Physaliphora (EP) is a benign lesion originating from the developing notochord, similar to chordoma. We report a case of cervical ecchordosis physaliphora in an elderly man who presented with hemihypoaesthesia and contralateral hemiparesis. Although the term ecchordosis physaliphora for the benign, hamartomatous lesion at the clivus is now widely accepted, there is some confusion about its distinction from intradural chordoma, 2, 7, 8 that is the main differential diagnosis on the basis of the same preferential location. @article{Takeyama2006NotochordalRM, title={Notochordal remnant-derived mass: ecchordosis physaliphora or chordoma? Recognition of the imaging features of ecchordosis physaliphora is helpful in suggesting the diagnosis and differentiating the lesion from chordoma. Titles and abstracts were then reviewed to identify cases of intradural chordomas or ecchordosis All the ecchordoses were EMA positive whereas only nine chordomas were positive, seve difn of them fusely and two focally. Patient with multiple myelitic lesions. Immunohistochemistry of Ecchordosis Physaliphora and Chordoma - Volume 17 Issue 4 Although ecchordosis physaliphora and chordoma share similar biological behaviour, they are two separate entities that require different management.3 Differentiation between them is Unlike chordomas which are often symptomatic due to brainstem or cranial nerve compression, patients with ecchordosis physaliphora are usually asymptomatic. Positive diffuse staining with Ecchordosis physaliphora is a congenital benign hamartomatous lesion derived from notochord remnants, usually located in the retroclival prepontine region, but can be found anywhere from the skull base to the sacrum. There has been some controversy as to whether intradural chordoma and large ecchordosis physaliphora are different entities. No specimen showed CEA reactivity. 2006 Dec;38 (6):599-600. doi: 10.1080/00313020601023948. ecchordosis physaliphora: ( ek'kor-d'sis fiz'a-li'fr- ), A notochordal rest (fragment of embryonic tissue) of the cranial clivus that may form a small tumor. This reflects the usual No specimen showed CEA reactivity. Objective: Purely intradural clival chordomas are rare neoplasms, and only a few cases have been reported.

A systematic electronic article search was conducted through Medline between 1974 and 2013, using the Medical Subject Heading terms chordoma, ecchordosis physaliphora, notochord, bone neoplasms, and skull base neoplasms. 4 EP is a benign notochordal remnant that can present in the intradural space dorsal to the clivus or sacrum. First, the similar staining properties of chordoma and ecchordosis physaliphora support the embryologic hypothesis of their common origin from the fetal notochord. Notochordal remnant-derived mass: ecchordosis physaliphora or chordoma? Second, they indicate First, the similar staining properties of chordoma and The 6-mm asymptomatic gelatinous lesion was Chordomas are hyperintense in both T1- and T2-weighted MRI scans, whereas ecchordosis physaliphora is hypointense in T1-weighted and hyperintense in T2-weighted MRI, There has been some controversy as to whether intradural chordoma and large ecchordosis physaliphora are different entities. Some authors (such as Wolfe et al.) proposed the name 'intradural chordoma' for all intradural notochordal remnant lesions 8. A and B, Sagittal and transverse T2-weighted 3-mm images incidentally show a round, retroclival ecchordosis physaliphora being spared in the dark signal intensity of CSF-related pulsation artifacts. neural arch > vertebral body; thoracic spine is the most commonly Ecchordosis physaliphora is a rare congenital benign hamartomatous lesion originating from nodal cord remnants. We review the problems of the differential diagnosis of noto-chordal remnants apropos of a case of the incidental autopsy finding of EP in a 78-year-old man, who died due to heart infarction. All the ecchordoses were EMA positive whereas only nine chordomas were positive, seve difn of them fusely and two focally. MRI showed a well defined, non-enhancing extradural mass lesion on the dorsal No ecchordosis or chordoma was carcinoembryonic-antigen positive. DOI: 10.1080/00313020601023948 Corpus ID: 44809939; Notochordal remnant-derived mass: ecchordosis physaliphora or chordoma? Two completely intradural extraosseous tumors with the histologic appearance of chordoma or ecchordosis physaliphora caused symptoms and, in 1 case, ultimately the death of a 44-year Search Strategy. Our patients lesions are contrast enhancing and multicentric; therefore, the diagnosis of multicentric chordoma was made. Notochordal remnant-derived mass: ecchordosis physaliphora or chordoma? Ecchordosis physaliphora does not demonstrate enhancement in post-contrast images, whereas chordoma usually enhances considerably in post-gadolinium study. Pathology. Of these cases, only three have demonstrated clear etiologyecchordosis physaliphora (EP) 2 3 or chordoma. Ecchordosis physaliphora arise from remaining notochord cells along the axis of the spine after embryogenesis. Ecchordosis physaliphora (EP) is a notochordal remnant tissue rarely encountered during routine clinical practice.

First, the similar staining properties of chordoma and ecchordosis physaliphora support the embryologic hypothesis of their common origin from the fetal notochord. Ecchordosis physaliphora is usually asymptomatic. Both ecchordosis and When a retroclival mass is established on MRI, any associated osseous stalk should be evaluated on thin-section CT as in our case which is classical for the diagnosis of Ecchordosis Physaliphora. standard test for the diagnosis of ecchordosis physaliphora is brain MRI with and without contrast as well as pathology testing [1,8,9]. Second, they This study supports the concept that chordomas arise from 2006 Dec;38 (6):599-600. doi: 10.1080/00313020601023948. The reported cases present features similar to ecchordosis physaliphora, which is a We report complete resection of asymptomatic, extradural EP in the sphenoid sinus using an endoscopic transsphenoidal It is worth mentioning, however, that ecchordosis physaliphora and chordoma are histologically indistinguishable in small fragmentary specimens, and are generally differentiated by ex am in g thrs, wld of v [1]. Positive diffuse staining with There are no multicentric cases of ecchordosis physaliphora in the literature to date. They are }, author={Junji Takeyama and Toshiaki Hayashi and Reizo Shirane}, journal={Pathology}, year={2006}, Muhammad usman Jawad. Both ecchordosis and chordoma cells have morphologic features of both epithelial and mesodermal character. and ecchordosis physaliphora (EP) ( 1 3 ). Chordoma cells possessed a more prominent Golgi apparatus, an endoplasmic Unfortunately, Ecchordosis cells had nuclear inclusions, dense-core membrane-bound granules and subcytoplasmalemmal linear densities, not previously described.

These lesions usually do not produce any significant symptoms The differential diagnosis of EP also includes chordoma, dermoid, epidermoid, arachnoid cysts and partially thrombosed vertebrobasilar aneurysm. Pathology. 2010, Spine. This is histopathologically indistinguishable from Ecchordosis physaliphora and intradural chordoma share some similarities that may be misleading and may even result in the wrong diagnosis and therapy. Ecchordosis physaliphora is a rare congenital, benign, hamartomatous, retroclival mass derived from notochordal tissue that is typically located intradurally in the prepontine cistern. These findings are interesting for two reasons. A comparative study of the ultrastructure of two cases of ecchordosis physaliphora and of two chordomas demonstrated outstanding similarities in the cells composing these two entities. ecchordosis physaliphora (EP) and benign notochordal (BNCT), or aggressive ones like chordoma. A diagnosis of chordoma was less likely in this patient because these tumors usually produce symptoms that suggest brainstem involvement or cranial nerve palsies, that show bone destruction, and that enhance with contrast material administration ( 1 , 3 9 ). Both ecchordosis and chordoma cells have morphologic features of both epithelial and mesodermal character. This study supports the concept that chordomas arise from heterotopic notochordal remnants in the cranio-vertebral canal.
