title: Primary lumbar hernia: A rarely encountered hernia.
abstract: BACKGROUND
  Lumbar hernia is an uncommon abdominal wall hernia, making its diagnosis and management a challenge to the treating surgeon. Presentation may be misleading and diagnosis often missed. An imaging study forms an indispensable aid in the diagnosis and surgery is the only treatment option.
  
  
  METHODS
  A 42 year old male presented with history of pain in lower back of 4 years duration and was being treated symptomatically over 4 years with analgesics and physiotherapy. He had noticed a swelling over the left side of his mid-back and consequently on examination was found to have a primary acquired lumbar hernia arising from the deep superior lumbar triangle of Grynfelt. Diagnosis was confirmed by Computed Tomographic imaging.
  
  
  CONCLUSIONS
  A lumbar hernia may be primary or secondary with only about 300 cases of primary lumbar hernia reported in literature. Lumbar hernias manifest through two possible defects in the posterior abdominal wall, the superior being more common. Management remains surgical with various techniques emerging over the years. The patient at our center underwent an open sublay mesh repair with excellent outcome.
  
  
  CONCLUSIONS
  A surgeon may encounter a primary lumbar hernia perhaps once in his lifetime making it an interesting surgical challenge. Sound anatomical knowledge and adequate imaging are indispensable. Inspite of advances in minimally invasive surgery, it cannot be universally applied to patients with lumbar hernia and management requires a more tailored approach.
