Differential Diagnosis for Mild Tuft Hair in Sacral Crease

  • Single Most Likely Diagnosis
    • Spina bifida occulta: This condition is characterized by a small gap in the spine, which can be associated with a tuft of hair in the sacral area. The presence of mild tuft hair in the sacral crease is a common cutaneous marker for spina bifida occulta.
  • Other Likely Diagnoses
    • Dermal sinus: A congenital anomaly that can present with a tuft of hair, often associated with a pit or dimple in the skin. It's a possible cause for the observed symptom.
    • Lipoma: A benign fatty tumor that can occur in the sacral area and may be associated with a tuft of hair.
  • Do Not Miss Diagnoses
    • Spinal dysraphism: A group of congenital anomalies that affect the spine, including spina bifida, diastematomyelia, and tethered cord syndrome. These conditions can have serious consequences if left untreated, making early diagnosis crucial.
    • Meningocele or myelomeningocele: More severe forms of spina bifida that can present with a tuft of hair in the sacral area. Early detection is vital to prevent further complications.
  • Rare Diagnoses
    • Teratoma: A rare type of tumor that can occur in the sacral area and may be associated with a tuft of hair.
    • Sacral agenesis: A rare congenital anomaly characterized by the underdevelopment or absence of the sacrum, which can be associated with a tuft of hair in the sacral area.
