Context:
Bony lesions involving the cranium and spine have a wide range of etiologies, ranging from congenital, traumatic, inflammatory, to neoplastic.
Aim:
The aim was to analyze the histological spectrum of various bony lesions of cranium and spine received as biopsies from the neurosurgery department in our hospital.
Materials And Methods:
There were 123 cases of bony lesions of cranium and spine diagnosed over a period of 5 years during 2015-2019 in the neuropathology laboratory. These cases were studied retrospectively.
Results:
Out of the total 123 cases of bony lesions analyzed, 75 affected the cranium and 48 affected the spine. Overall, neoplastic lesions (83) were more frequent than the nonneoplastic lesions (40). In the cranium, neoplastic lesions (66/75) outnumbered the nonneoplastic ones (9/75), whereas in the spine, nonneoplastic lesions (31/48) were more common. Chordoma (40/83) was the most common neoplasm, whereas tuberculous osteomyelitis (30/40) was the most common nonneoplastic lesion encountered. Majority of the patients were adult males aged between 21 and 50 years. Rare lesions such as spinal osteochondroma, poorly differentiated neoplasm metastatic to the cervical spine from a primary salivary gland neoplasm, spinal metastasis of a glioblastoma, and intraosseous meningioma of cranium were recorded.
Conclusions:
The study provides epidemiological information regarding the incidence and nature of bone lesions of the spine and cranium.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Cranial Bones: Lateral View
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...
Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
