Bochdalek hernia is the commonest type of diaphgramatic hernia. It was first described in 1754 by Mc Culley. In 1848 Bochdalek described that diaphragmatic hernia occurs due to improper fusion of posterolateral foramina of diaphragm. We present a case of 48 year old female who first presented with chief complaints of epistaxis with cervical and lumbar back pain. She was diagnosed as a case of multiple myeloma and started on drug thalidomide. On follow ups the patient started having respiratory complaints for which she underwent X-ray chest and CT thorax which further revealed that patient had developed a new onset bochdaleks hernia as X-ray chest on her previous visits was normal. With no other preceding risk factors or previous respiratory complaints, we came to a conclusion that this could be a case where thalidomide, which till now has only experimentally proven to cause hernia, may be a cause of this new onset bochdaleks hernia.
