“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] However, with the development of serologic techniques and radiologic instruments, proper diagnosis of cerebral sparganosis could be established before surgery. To date, to our knowledge imaging findings of cerebral sparganosis have been reported sporadically, most of which 4,5,17,18 were published in the 1990s, but the features on CT and MR examinations had not previously been described in detail. The purpose of this study was to analyze retrospectively if CT and MR examinations of cerebral sparganosis can be used for correct preoperative diagnosis and to search for new findings.…”

“…In the present study, all the patients of the live group showed a highly attenuated lesion on the precontrast CT. There has been no study that has mentioned this highly attenuated lesion, and this type of lesion seemed to be regarded in the previous reports as calcification or petechial hemorrhage (10)(11)(12)(13)(14)(15). However, we consider this lesion to be a live worm because of the following reasons.…”

“…The reason why the worm showed high attenuation on the precontrast CT and such MR signal intensities is not fully understood. The existence of high proteinaceous secretory granules, corpuscles or muscles in the worm might contribute to this CT attenuation and MR intensity (10)(11)(12)(13)(14). Besides the highly attenuated lesion, punctate calcifications were also seen in both groups, and the attenuation of the punctate calcifications appeared much higher than that of the worm on CT.…”

“…Second, in an acute stage of cerebral sparganosis when the worm is alive, it produces local inflammation, resulting in a surrounding mass effect and irregular nodular enhancement (9). Third, after passage or migration of the live sparganum worm, the worm's previous cortical or white matter site becomes atrophied with ipsilateral ventricular dilatation (10)(11)(12)(13)(14). Sometimes in these atrophied areas, punctate calcifications may remain with surrounding enhancement.…”

“…This disease has been reported worldwide, but it is most common in East Asia (2)(3)(4)(5)(6)(7)(8)(9). The CT and MR imaging features of cerebral sparganosis have been well described (10)(11)(12)(13)(14). However, no specific imaging features of cerebral sparganosis that indicate the presence of a live worm have been yet reported, despite its clinical importance, because of the rarity of surgically-confirmed cases with extraction of a live worm.…”

Purpose: The purpose of this study is to describe the characteristic features of cerebral sparganosis with live worm on CT and MRI as compared with the characteristic CT and MRI features of degenerated cerebral worms. Materials and Methods: Twelve patients with surgically-proven live worms (the live group) and 13 patients with degenerated worms (the degenerated group) were included in this study. We retrospectively reviewed the CT scans of all the patients and the MR images of 19 patients. Results: The live group showed highly attenuated lesion (50-70 HUs for the CT number) on precontrast CT with surrounding enhancement extending to the cortical surface, a mass effect and change of the location and shape of the enhancing lesion on the follow-up images, whereas the degenerated group showed punctate calcification (more than 130 HUs) with surrounding enhancement and cerebromalacia in 77% of the subjects (p<.01). The highly attenuated lesion had an amorphous nodular or nodulotubular shape, and these lesions were slightly hyperintense on the T1-weighted MR images and hypointense on the T2-weighted MR images. Conclusion:In patients with cerebral sparganosis, live worm infection is highly suggested if there is a focal amorphous hyperattenuated lesion on the precontrast CT with a surrounding mass effect, irregular nodulotubular enhancement extending to the pial surface and change of the enhancing lesion on the follow-up images.

Parasitic lesion of the insula suggesting cerebral sparganosis: case report

et al. 2000

View full text Add to dashboard Cite

Cerebral sparganosis, a parasitic disease, rarely produces a chronic active inflammatory response in the brain. Clinically and radiographically the process may mimic a neoplasm. We report a 30-year-old man who underwent surgical exploration for a mass in the insular cortex. Histology revealed a densely fibrotic mass heavily infiltrated with plasma cells and lymphocytes, in which were embedded parasitic forms consistent with sparganosis. We describe the MRI appearances and pathologic features. Intracranial mass lesions secondary to sparganosis must be considered in patients with a history of travel to endemic areas, especially Asia.
