Delayed diagnosis and successful mesh repair of a Grynfeltt-Lesshaft lumbar hernia in a 65-year-old man in India: a case report

다국어 초록 (Multilingual Abstract)

The literature has described approximately 300 cases of lumbar hernia. Because of its rarity, the condition is often misdiagnosed, leading to delayed treatment. We report the case of a 65-year-old man who had complained for 5 years of a lump in his left lumbar region. There was no history of prior trauma or surgery. The mass gradually increased in size and was associated with vague dragging pain. The diagnosis of Grynfeltt-Lesshaft lumbar hernia was made based on clinical suspicion and ultrasound findings. The patient underwent open sublay mesh repair and recovered without complications. This case is noteworthy for the 5-year delay in diagnosis and management without computed tomography or magnetic resonance imaging, underscoring the role of high clinical suspicion and ultrasound-based diagnosis in resource-limited settings. Although rare, lumbar hernia should be considered in the differential diagnosis of a lumbar mass. Early diagnosis with ultrasound, contrast-enhanced computed tomography, or magnetic resonance imaging can help prevent complications. This case raises awareness of lumbar hernia and outlines available surgical options for treatment.
