A 50 year old Mehta, presents to his physician every month complaining about headache which he suspects could be a brain tumour. Despite having done a normal MRI scan he is not convinced that the diagnosis ruled out. The physician thinks that he misinterprets the body sentsations and is ovely concerned about his health. What is the likely diagnosis?

The patient in the question presents with anxiety about having a paicular diagnosis like a tumour. He is not convinced by the evidence against it. He has a belief that he has a life threatening diagnosis. This is indicative of Hypochondriasis. Hypochondriasis can be a severe anxiety or in worse cases Delusional Hypochondriasis which can be considered as psychosis. In somatisation disorder the patient is often worries about multiple symptoms, not a paicular diagnosis. Pituaitary tumour could present with a bitemporal hemianopia. Capgras syndrome is a misidentification delusion.
