“…Tubbs et al [3] in their report on a persistent occipital sinus emphasized the importance of recognition of such an anatomic variation in the treatment of clival epidural hematomas. Failure to recognize it may even lead to a fatal outcome.…”

“…Woodhall avait mené (1936) une étude (citée par N. Balak et al [1]) sur les variations des sinus veineux du crâne, dont le sinus occipital faisait partie. Il décline lui-même quelques variations, notamment de position avec le sinus occipital oblique [2]. Des dédoublements sont aussi possibles.…”

“…Comme nous l'avons mentionné dans notre série, le sinus occipital et ses variations jouent un rôle important dans la dilatation des sinus latéraux, et peuvent même assurer une voie de drainage veineux primordiale lorsque les sinus latéraux sont peu développés [8]. Le réseau veineux occipital peut régresser lorsque les flux veineux se répartissent dans les sinus duraux plus larges, à l'acquisition de la station érigée, sans doute rançon de la bipédie [2]. Ainsi, selon les travaux antérieurs, une régression du sinus occipital liée à l'âge est possible [9].…”

“…Il se place dans l'épaisseur de la dure-mère et longe le cervelet depuis le confluent des sinus jusqu'au foramen magnum [1]. Son réseau involue lorsque la majorité du flux veineux emprunte les sinus duraux larges, à l'acquisition de la position debout [2]. Cependant, lorsqu'il persiste, il existe un risque hémorragique non négligeable à l'ouverture de la dure-mère, notamment en chirurgie des tumeurs de fosse postérieure.…”

“…Variations in the occipital sinus are important for neurosurgical planning in the posterior cranial fossa and deviation from the expected midline location should be reported. If the occipital sinus deviates from the midline and joins a sigmoid sinus inferolaterally, it is known as an oblique occipital sinus (Fig B–D) . Superiorly, an oblique sagittal sinus communicates with the confluence of sinuses, transverse sinus, straight sinus, or superior sagittal sinus .…”

Variations in the venous drainage of the central nervous system can have imaging and clinical findings that mimic pathology, presenting a challenge for neuroimagers and clinicians. Patients with these variants may undergo unnecessary testing, and patients with pathology may receive delayed diagnoses because of overlap with benign findings. Consequently, the accurate identification of venous variations on cross-sectional imaging and angiography and their potential causes are critical for differentiating benign imaging variants from potential pathologic processes requiring further evaluation. For example, in the epidural space, benign dilation of the epidural venous plexus may be mistaken for evidence of a fistula, abscess, or metastasis. Hypoplasia of a dural venous sinus or an arachnoid granulation may mimic venous sinus thrombosis. The superior ophthalmic vein may demonstrate benign dilation in intubated patients, mimicking thrombosis, increased intracranial pressure, orbital varix, inflammatory pseudotumor, or other conditions. Furthermore, certain venous variations, such as the occipital sinus or emissary veins, may complicate surgery or herald pathology and should be reported. In addition, some supposedly benign variations, such as the developmental venous anomaly, can be complicated by pathology. The objective of this review article is to provide a descriptive and pictorial review of common anatomic and physiologic variations in the venous drainage system of the brain, spine, and orbits that can mimic pathology. Neuroimaging findings of related pathologies and differences in clinical presentations will also be discussed to assist in the approach to differential diagnosis.
