Vertebral hydatid cyst infection (Echinococcus granulosus): a case report

Re: Vertebral hydatid cyst infection (Echinococcus granulosus): a case report

“…In conclusion, Normelli et al [8] apparently have some useful information on this serious condition, but they do not convey it in their article. For example, they do not offer any conclusions based on their patient in the Discussion section of their case report.…”

“…Unfortunately, Normelli et al [8] presented only a sagittal thoracolumbar MR image of their case, and they state in their case report that at surgery the infection was more extensive than was indicated by the radiological information obtained from MR images regarding the extension of the disease within the spinal canal. We do not agree with Dr. Normelli et al's opinion of the results of the MRI investigation as "false-negative".…”

“…When the embryo reaches the vertebral body, it develops into its larval stage, known as the intraosseous stage of hydatid infection. Histologically, there are three layers of the cyst wall from the outermost to the innermost -pericyst, acellular laminated membrane, and germinal layer -as stated by the authors [8]. The organism grows within the intratrabecular space and endogenous vesiculation results in the formation of daughter cysts within the parental cyst, destroying the bone like a tumor.…”

“…There are, however, several points that were not made clear by Normelli et al [8], and we would like to draw the attention of the readers of European Spine Journal to a few that we consider to be important.…”

Gigantic retroperitoneal hydatid cyst originating from vertebrae

“…1,3,4 KH'in vertebra tutulumu endemik bölgelerde bile oldukça nadirdir. [1][2][3][4][5][6][7] Vertebra yerleşimli KH silik bir klinik tablo yaratır ve genellikle kemik korteksi aşıp çevre yumuşak dokuya ulaştığı ileri evrelerde tanı konulabilir. 4,5 Prognoz genellikle kötüdür, multipl nüksler ve paraplejiye neden olabilir.…”
