title: Maxillary sinus marrow hyperplasia in sickle cell anemia.
abstract: Marrow hyperplasia is a sequela of sickle cell anemia (SCA) and may be seen in the skull in children after 5 years of age [1]. The facial bones, except for the mandible and orbits, are usually not involved [1-3]. We report an unusual case of a 28-month-old black boy with SCA who presented with extensive marrow hyperplasia of the maxillary sinuses in addition to severe calvarial and mandibular changes. The imaging characteristics on CT (similar to other sites of marrow hyperplasia) and MR (low signal on both T1 and T2 sequences) should aid in making the correct diagnosis.
