title: [Differential diagnosis of reduced uptake images revealed by bone scan: about a case of acute lymphoblastic leukemia].
abstract: If increased uptake during bone scan usually bring to light many bone pathologies, reduced uptakes are a rare occurrence and they require careful analysis to avoid erroneous interpretations. We report the case of a 17-year old admitted with diffuse bone pain, hypercalcemia and thrombopenia. Bone scan showed areas of low uptakes. Bone marrow tests allowed the diagnosis of acute lymphoblastic leukemia. This case report aims to discuss the main differential diagnoses based on such bone scan abnormalities.
