The occipital sinus is often thought of as a redundant vestigial structure in adults. However, in rare cases, it can form the dominant route of intracerebral venous drainage, with a risk of significant surgical morbidity if unrecognised. We present an illustrative case describing this anatomical variant and tailoring of a midline suboccipital craniotomy to allow resection of a fourth ventricular epidermoid tumour with preservation of a dominant occipital sinus, and a review of the published literature.

Clinical spectrum of positional downbeat nystagmus: a diagnostic approach.

J Neurol

January 2025

Department of Neurology, University of Chicago, 5841 South Maryland Avenue, Chicago, IL, 60637, USA.

Positional downbeat nystagmus (pDBN) is a common finding in dizzy patients, with etiologies ranging from benign paroxysmal positional vertigo (BPPV) to central vestibular lesions. Although peripheral pDBN often presents with distinct clinical features that differentiate it from BPPV, diagnosing its etiology can be challenging. A thorough clinical evaluation, including the physical characteristics of the nystagmus, response to positional maneuvers, and neurological findings, is often sufficient to diagnose conditions that provoke pDBN such as anterior canal BPPV, atypical posterior canal BPPV, and central causes.

A morphometric analysis of the cranial base in trigonocephaly.

J Craniomaxillofac Surg

January 2025

Department of Clinical Anatomy, School of Laboratory Medicine and Medical Sciences, University of KwaZulu-Natal, Durban, South Africa. Electronic address:

Trigonocephaly occurs when the metopic suture fuses prematurely. Few studies have documented the morphometry of the entire anterior cranium in trigonocephaly and not on the morphometric changes to the cranial fossae alone. Thus, this study aimed to determine and compare the dimensions of the anterior cranial fossa (ACF) in trigonocephaly and control groups.

Background: Trigeminal neuralgia is a disease characterized by severe facial pain that significantly reduces patients quality of life. Trigeminal neuralgia is subcategorized as idiopathic, classic or secondary. Magnetic resonance imaging is the basis for classification, but neurophysiological tests are also used.
