(psammoma or calcific bodies) may be seen.
Ganglioglioma often presents radiologically as a mural nodule within a cyst and exhibits several helpful diagnostic features, including higher cellularity, dysmorphic or binucleate neurons unassociated with pink cells, pilocytic morphology of the glial component, calcospherites
, desmoplasia, and perivascular lymphocytic infiltrates.
Many of Wagge's conclusions were formed by Iris earlier experiments (Wagge 1951) that showed migrating epithelial cells were responsible for secretion of both the organic membranes and the crystals of calcium carbonate within the calcospherites
Microscopically, malakoplakia is characterized by aggregates of histiocytes, the Von Hanseman cells, with Michaelis-Gutmann calcospherites
Previous reports of fine-needle aspiration of dermoid cysts from other sites have demonstrated various cytologic findings, including nucleated and anucleated squamous cells, hair, keratinous debris, cholesterol, calcospherites
(calcium deposits), and inflammatory cells.
