The crucial role of MRI and its characteristic features in accurate preoperative diagnosis will be emphasized.…”

Objective: Extradural arachnoid cysts (EACs) are rare causes of spinal cord compression and cauda equina. These benign lesions appear in the literature mainly as single case reports. In this article, we present the largest series found in literature, with four new cases of spinal extradural arachnoid cysts. The characteristic imaging features, details of surgical steps and strategies to prevent postoperative kyphosis in this cystic pathology will be discussed.

“…Primary spinal hydatid cyst is extremely rare (1)(2)(3). Spinal hydatid cysts are usually situated in the dorsal region and generate medullary or radicular symptoms according to their location (4). They give rise to fluctuating symptoms as an effect of internal change in pressure resulting from changes in the hydrostatic pressure of the cerebrospinal fluid caused by physical efforts, such as coughing and sneezing (5).…”

Background: Primary spinal hydatid cysts are uncommon and account for 1% of all cases of hydatid disease. Echinococcus granulosus is most often responsible for the cyst hydatid. Intradural, extramedullary involvement is rare. When the cysts do not demonstrate typical magnetic resonance imaging findings, the differential diagnosis is more complex. Method: Case report. Findings: An isolated primary hydatid cyst of the spine in a 35-year-old man that appeared to be an arachnoid cyst on preoperative radiographic examination. Conclusion: Hydatid cysts that lack the typical radiographic appearance may be mistaken for arachnoid cysts. Misdiagnosis has serious implications for surgical intervention and long-term care.

“…These lesions occupy the intraspinal space and sometimes cause neurological disturbances such as compression myelopathy [McCrum and Williams, 1982;Prevo et al, 1999;Chang et al, 2004;Novak et al, 2005]. Although SEDAC represents 1% of all primary spinal cord tumors [Elsberg et al 1934], the number of reported cases has recently increased with the more widespread use of MRI [Takagaki et al, 2006].…”

Spinal extradural arachnoid cysts (SEDAC) are lesions communicating to the subarachnoid space of the spinal canal via a dural defect. SEDAC occupies intraspinal space and sometimes causes neurological disturbances. Although most reported cases are sporadic, several familial cases have been described, suggesting a genetic etiology. Here we report on a family with SEDAC inherited in an autosomal dominant mode. Detailed study showed that the family has the lymphedema-distichiasis syndrome. Among family members examined, a total of ten in two generations manifested all or some of the following features: SEDAC, distichiasis and lymphedema. Seven had spinal cysts, four had both SEDAC and distichiasis, and one had SEDAC distichiasis and lymphedema; three did not have SEDAC. These findings, together with rarity of both distichiasis and lymphedema in the general population, support that all of the ten members were affected with one clinical entity, the lymphedema-distichiasis syndrome. The distribution of features illustrates the variable expressivity of clinical manifestations. Although FOXC2 mutation analysis was not performed in our family, it is likely that SEDAC is a component manifestation of lymphedema-distichiasis syndrome and more consistent in our family than those reported.
