Case Discussion

Please See Radiopedia /  Refer Diffrential Diagnosis Texts for "pathognomic Radiological sign" of 'Bone with in A Bone Appearance'

In our case who was treated outside as for provisional diagnosis of thalassemia / sickle cell anemia in view of organomegaly and chronic illness and anaemia ;

However on hematological investigations the provisional diagnosis was ruled out and based on classical radio-logical sign and further clinical history & insight ( progressive deafness and blindness) the diagnosis of " Autosomal dominant osteopetrosis "  was suggested and was confirmed later from treating physician/pediatrician .

Take home message : Importance is of not only recognizing "classic radio-logical sign " but eliciting clinical history with correlation of organomegaly and signs and symptoms yields best diagnosis and aid in proper clinical outcomes i.e.  highlights role of Clinical Radiologist
