Radiological impression of Lumbar and hip MR before excisional biopsy ; hematologic disorder such as leukemia, lymphoma, multiple myeloma • Radiological impression of lung CT before biopsy ; active cavitary pulmonary tuberculosis
Pathological Diagnosis • Langerhans’ cell histiocytosis (LCH) by excisional iliac bone biopsy • Langerhans’ cell histiocytosis (LCH) by lung biopsy
Discussion • LCH of bone is a disorder of histiocytic proliferation with variable and often unpredictable behavior. • Ranged from 3 months to 50 years old (mean, 12 years; median, 10 years) in 245 patients by Mayo Clinic. • The skull was the most frequent osseous site. • Diabetes insipidus was documented in 12% of the patients.
