Background: Femoral neuropathy is a clinical condition that may be associated with a wide variety of etiologies and may cause severe walking difficulties. Symptoms and signs of femoral neuropathy vary depending on the severity and level of the lesion. Clinical examination, electrophysiological studies, and radiological evaluation are very important in diagnosis. Treatment is planned according to the symptoms and the underlying cause, and surgical or conservative approaches can be applied. Case Presentation: A 39-year-old man presented with weakness and thinning in the right leg and numbness, burning, and tingling in the medial of the right lower extremity. A diagnosis of idiopathic femoral nerve neuropathy was made as a result of neurological examination, electrophysiological, and radiological evaluations. Conclusion: Isolated femoral neuropathy is a rare condition that can be misdiagnosed and may result in treatment delays and permanent damage. Clinicians must be aware of this clinical picture.
