Lateral Ventricle Atypical Teratoid/Rhabdoid Tumor (AT/RT): Case Report and Review of Literature

A 4-year-old male child presented with features of raised intracranial pressure due to tumor in the left lateral ventricle with shunt blockage. Ventriculoperitoneal shunt was done earlier (one month ago). Craniotomy and gross total excision of the tumor was achieved. Histopathological examination was suggestive of Atypical Teratoid/Rhabdoid tumor. Patient relatives were not compliant with the advice for adjuvant therapy and patient expired after three months of definitive surgery due to aggressive course of the disease. To the best of our knowledge only six cases of AT/RT of the lateral ventricle in pediatric population has been described in literature. The tumor may mimic radiologically with benign pathology and can have an aggressive course with poor outcome. Differential diagnosis of AT/RT must be kept in cases of lateral ventricle tumor in pediatric population.
