Cranial Bones: Lateral View

2.1K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Area of Science:

  • Oncology
  • Head and Neck Surgery
  • Radiology

Background:

  • Ewing's sarcoma typically affects long bones but can occur rarely in the head and neck.
  • Maxillary sinus involvement is an exceptionally rare presentation of this pediatric malignancy.

Purpose of the Study:

  • To report a rare case of Ewing's sarcoma in the maxillary sinus.
  • To emphasize the importance of advanced imaging and histopathological markers in early diagnosis and treatment planning.

Main Methods:

  • A 12-year-old female presented with facial swelling.
  • Diagnostic workup included CT and MRI of the paranasal sinuses.
  • Histopathological examination (HPE) and immunohistochemistry (IHC) confirmed Ewing's sarcoma with CD-99 positivity.

Main Results:

  • Imaging revealed a mass in the left maxillary sinus with orbital and intracranial extension.
  • Biopsy confirmed Ewing's sarcoma, a rare pediatric cancer.
  • The patient received radiotherapy due to the extensive nature of the disease.

Conclusions:

  • Early diagnosis of maxillary sinus Ewing's sarcoma is critical for timely intervention.
  • Combined chemoradiotherapy and close follow-up are essential for better survival rates.
  • Advanced imaging and IHC markers facilitate prompt diagnosis and treatment of this rare tumor.
