Differential Diagnosis

  • Single Most Likely Diagnosis
    • Lumbar Radiculopathy: The patient's symptoms of sharp shooting pain down her right leg, exacerbated by rest and relieved by activity, are consistent with lumbar radiculopathy. The presence of a lipoma in the lower back may be coincidental, and the patient's pain may be due to a herniated disc or other spinal pathology.
  • Other Likely Diagnoses
    • Lipoma-related nerve compression: Although the lipoma is described as soft and non-tender, it is possible that it is compressing a nearby nerve, causing the patient's symptoms.
    • Piriformis syndrome: The patient's symptoms of pain and numbness in the right leg could be due to compression of the sciatic nerve by the piriformis muscle.
    • Degenerative disc disease: The patient's age and symptoms of back pain and radiculopathy are consistent with degenerative disc disease.
  • Do Not Miss Diagnoses
    • Cauda equina syndrome: Although the patient denies bowel or bladder symptoms, cauda equina syndrome is a medical emergency that requires prompt diagnosis and treatment. It is characterized by low back pain, sciatica, and neurological symptoms such as numbness or weakness in the legs.
    • Spinal tumor: A spinal tumor could be causing the patient's symptoms, and it is essential to rule out this possibility with further imaging studies.
    • Infection or abscess: An infection or abscess in the spine or soft tissues could be causing the patient's symptoms, and it is crucial to consider this possibility, especially if the patient has a fever or other systemic symptoms.
  • Rare Diagnoses
    • Tarlov cyst: A Tarlov cyst is a rare condition characterized by a cystic lesion in the spine that can cause nerve compression and pain.
    • Arachnoiditis: Arachnoiditis is a rare condition characterized by inflammation of the arachnoid membrane, which can cause pain, numbness, and weakness in the legs.
    • Liposarcoma: Although the lipoma is described as benign, it is essential to consider the possibility of a liposarcoma, a rare type of cancer that can cause similar symptoms.
