Answer for BIR CoW 02 Aug 2020
Findings
Ultrasound reveals a solid cystic mass in the left temporal region. T2 demonstrates large cystic component, T1 bright signals demonstrate internal fat. Mass shows heterogenous enhancement.
Diagnosis : Mature intracranial teratoma.
Discussion
•Most common intracranial mass lesion in the new born : third to one half of cases
• Composed of all 3 germ cell layers
• Histology: Mature / Immature
•Head and neck second common site after sacrococcygeal
• Location: prefer midline (Pineal> suprasellar> ventricles > posterior fossa)
• Presentation: massive lesion replacing intracranial contents, small tumour with hydrocephalus, extension into orbit and nose, incidental finding in stillborn
• Imaging: heterogeneous supratentorial mass with fat, calcification and soft tissue
• Immature teratomas: less defined margins, few cyst/caclcification, mimic other tumours
