Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

3.9K
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...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

7.5K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Area of Science:

  • Oncology
  • Radiology
  • Pathology

Background:

  • Chondrosarcoma is a cartilaginous tumor typically found in long bones and the pelvis.
  • Sinonasal chondrosarcoma represents a rare but significant clinical presentation of this tumor type.

Purpose of the Study:

  • To report a rare case of sinonasal chondrosarcoma in a young adult.
  • To highlight the diagnostic process and imaging characteristics of sinonasal chondrosarcoma.

Main Methods:

  • Case report of a 25-year-old patient with suspected sinonasal chondrosarcoma.
  • Diagnostic work-up included anatomopathological examination.
  • Cross-sectional imaging with facial magnetic resonance imaging (MRI) and computed tomography (CT) scan.

Main Results:

  • Anatomopathological examination confirmed sinonasal chondrosarcoma.
  • MRI and CT revealed an advanced, osteolytic tumor involving the hard palate and left maxillary sinus.
  • Radiological findings consistent with a cartilage matrix were observed.

Conclusions:

  • Sinonasal chondrosarcoma is an uncommon entity requiring careful diagnosis.
  • Histological assessment is crucial for confirming the diagnosis.
  • Cross-sectional imaging plays a key role in characterizing the extent and nature of the tumor.
