Foramen magnum stenosis and midface hypoplasia in C-type natriuretic peptide-deficient rats and restoration by the administration of human C-type natriuretic peptide with 53 amino acids.

PLoS ONE, 2019
C-type natriuretic peptide (CNP)-knockout (KO) rats exhibit impaired skeletal growth, with long bones shorter than those in wild-type (WT) rats. This study compared craniofacial morphology in the CNP-KO rat with that in the Spontaneous Dwarf Rat (SDR), a

Circumscribed Meningeal Melanocytic Neoplasms: CNS WHO Grade, Molecular Profile, and Clinical Outcomes

Brain Pathology, EarlyView.
In this study including 31 circumscribed meningeal melanocytic neoplasms (melanocytoma, intermediate‐grade melanocytic tumor [IMT], and melanoma), overall survival (OS) differed significantly among the groups, with melanoma showing significantly worse OS than melanocytoma and IMT showing intermediate OS between melanocytoma and melanoma.

How I do it - The "drum skin" duraplasty technique after foramen magnum decompression for Chiari malformations

, 2023
BackgroundChiari malformations are a spectrum of posterior cranial fossa anomalies characterized by herniation of the cerebellar tonsils through the foramen magnum. Surgery is the treatment of choice for selected patients with good postoperative outcomes.

Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)

Journal of Anatomy, Volume 246, Issue 4, Page 575-584, April 2025.
India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.

Occipital condyles interconnected by a bony bar

National Journal of Clinical Anatomy, 2016
Occipital condyles interconnected by a bony bar is a rare occurrence. During osteology demonstration of skull bones, one skull was identified which exhibited a bony bar bridging the anteromedial aspects of the occipital condyles. The bony bar was curved,

When Virchow's law fails: Crouzon syndrome as a test case for quantitative suture closure–endocranial shape relationships

Journal of Anatomy, EarlyView.
Crouzon syndrome shows preserved intracranial volume but profoundly altered endocranial shape, with disrupted allometric coupling relative to controls. Treating calvarial suture patency as a continuous, age‐adjusted variable reveals strong system‐level covariation with endocranial morphology, effects invisible to conventional categorical suture scoring.
