Glioblastoma with signet ring cell morphology: A diagnostic challenge.

Glioblastoma (WHO Grade IV), the most frequent malignant brain tumor, can have varied morphologic variations like epithelial/glandular structures, granular cells, and lipidized cells. Glioblastoma with signet ring cell morphology is very unusual and can mimic a metastatic carcinoma. These rare tumors may be just a morphological variant or may signify a different carcinogenic pathway.

Reduction en-masse of inguinal hernia with strangulated obstruction.

"Reduction en masse of inguinal hernia" means reduction/migration of a hernial sac into the properitoneal space. We report the CT findings in a case of reduction en masse with strangulated obstruction. CT scan demonstrated a hernial sac with fibrous constriction band at the neck, situated in the properitoneal space superior to the inguinal region, causing closed-loop obstruction.
