Computed tomography (CT) revealed intestinal wall calcification in patients with schistosomiasis japonica. Pathologic examination confirmed these calcifications are from deposited eggs of Schistosoma japonicum.

Area of Science:

  • Radiology
  • Pathology
  • Parasitology

Background:

  • Schistosomiasis japonica is a parasitic disease that can affect the intestines.
  • Intestinal wall calcification is a potential manifestation of chronic schistosomiasis.
  • Computed tomography (CT) is a key imaging modality for visualizing abdominal pathology.

Purpose of the Study:

  • To elucidate the pathological basis of intestinal wall calcification in Schistosoma japonicum infection.
  • To correlate computed tomography (CT) findings with pathological examination of intestinal specimens.

Main Methods:

  • Twelve patients with suspected schistosomiasis japonica underwent abdominal CT scans.
  • Eight intestinal specimens from five patients were analyzed pathologically and radiographically.

  • Correlation between CT findings and histopathological results was performed.

    • Main Results:

    • CT identified curvilinear or nodular calcifications in the colon (11 patients), appendix (2), and ileum (1).
    • Tram-track calcifications were observed in the sigmoid colon of five patients.
    • Pathology revealed calcified Schistosoma japonicum eggs predominantly in the submucosa and subserosa, explaining the tram-track appearance.

    Conclusions:

    • The observed extensive calcifications in the colon, including tram-track patterns, are indicative of deposited Schistosoma japonicum eggs.
    • CT imaging effectively visualizes the extent and pattern of intestinal calcification caused by schistosomiasis japonica.
    • Understanding the pathological basis aids in accurate diagnosis and management of intestinal schistosomiasis.
