case_images: A, Coronal section showing complete opacification of the left maxillary sinus
  with bony expansion. Heterogeneous densities are noted centrally within the
  maxillary sinus. B, Axial section showing scattered foci of opacification
  within the left maxillary sinus.

case_images: fig1-2152656720918874
case_images: A noncontrast computed tomography (CT) was ordered and revealed opacification and expansion of the left maxillary sinus that occluded the ostiomeatal unit consistent with a fungal ball (Figure 1(A) and (B)).
case_images: Intraoperative findings:the left maxillary sinus was filled with soft
  trabecular bone and fluid, without mucopurulent discharge

case_images: Intraoperatively, the maxillary sinus was noted to filled with spiculated osseous tissue (Figure 2).
case_images: A, 40x original magnification. Inflamed sinonasal mucosa and stroma (right)
  intermixed with fragments of trabecular bone and normocellular marrow
  (left). B, 200x original magnification. Cellular bone marrow containing all
  3 hematopoietic lineages (megakaryocytes, granulocytic precursors, and
  erythroid precursors) with erythroid hyperplasia, compatible with the
  patient's active sickle cell crisis and reticulocytosis.
