The solid part of this type of tumor has been well described in various reports and books, but characteristics of the cystic portion have remained unclear. Because adequate resection is required to ensure a favorable prognosis, information about the cyst is very important for diagnostic purposes and surgical planning. The authors report on the clinical and histological features of the cyst in a case of a DIA. A 12-month-old boy presented with vomiting. Contrast-enhanced magnetic resonance imaging revealed a strongly enhancing single-lobed large cyst located in the deep white matter, under the solid part of the tumor attached to the dura mater of the left frontal lobe. Both the solid and cystic portions of the tumor were surgically removed. The border between the cyst wall and surrounding white matter was unclear. Histologically, the cyst wall was composed of gliosis representing a rough accumulation of reactive astrocytes, lymphocytes, and small capillary vessels in edematous parenchyma, but no tumor cells. The present case and previous reports suggest that the cyst does not contain tumor cells, even if strongly depicted on contrast-enhanced neuroimaging, and that a thickly enhancing cyst wall indicates gliosis with accumulation of numerous small vessels.<\/jats:p>","DOI":"10.3171\/ped\/2008\/1\/2\/148","type":"journal-article","created":{"date-parts":[[2008,2,4]],"date-time":"2008-02-04T13:33:36Z","timestamp":1202132016000},"page":"148-151","source":"Crossref","is-referenced-by-count":13,"title":["Desmoplastic infantile astrocytoma and characteristics of the accompanying cyst"],"prefix":"10.3171","volume":"1","author":[{"given":"Takaaki","family":"Beppu","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuichi","family":"Sato","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriyuki","family":"Uesugi","sequence":"additional","affiliation":[{"name":"Pathology, Iwate Medical University, Morioka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasutaka","family":"Kuzu","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuniaki","family":"Ogasawara","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-0010148","series-title":"Acta Neuropathol (Berl)","first-page":"666","article-title":"Desmoplastic cerebral astrocytoma of infancy.
