Purpose: The present study aimed to evaluate the foramen venosum (FV) frequency, incidence, morphometry and relation with foramen ovale in an Indian population. The emissary vein passing through it may spread extracranial facial infections to the intracranial cavernous sinus. Due to its close proximity with the foramen ovale and its variable occurrence, awareness about its presence and anatomy is essential to neurosurgeons operating in this region.
Methods: 62 dry adult human skulls were studied for the occurrence and morphometry of foramen venosum, both at the middle cranial fossa and extracranial base of the skull. Dimensions were taken using Java-based image processing program, IMAGE J. After collection of data, appropriate statistical analysis was done.
Results: The foramen venosum was observed in 49.1% skulls. Its presence was noted more frequently at the extracranial skull base than in the middle cranial fossa. No significant difference was observed between the two sides. FV at the extracranial view of the skull base had a larger maximum diameter than in the middle cranial fossa; however, the distance between FV and the foramen ovale was found to be more at the middle cranial fossa than at the extracranial view of the skull base on both the right and left side. Variations in the shape of the foramen venosum were also observed.
Conclusion: The present study is not only of great importance to anatomists, but also to radiologists and neurosurgeons for better planning and execution of the surgical approach to the middle cranial fossa through the foramen ovale to prevent iatrogenic injuries.

An anomalous left hepatic vein opening independently of the coronary sinus into the right atrium was found in the cadaver of an 88-year-old Japanese man. This vein originated from the left lobe of the liver, perforated the diaphragm at the left side of the vena caval foramen and opened into the right atrium. The left hepatic vein anastomosed mutually with the middle hepatic vein at the level of venule.

An anomalous vein indicating the persistence of the hepatic segment of the inferior vena cava (left vena revehens) was found in a 60-year-old male cadaver. This vein emerging from the left lobe of the liver passed through the diaphragm at 3 cm leftward of the vena cava foramen and entered the coronary sinus at its termination, which in turn opened into the right atrium. A more detailed dissection of the liver showed that the ligamentum venosum originating from the left protal vein connected directly to the anomalous vein.

This investigation is based on measurements of 60 macerated adult European skulls from the Alexander-Ecker Collection at the Anatomy Department of the University of Freiburg. Computer tomographical (CT) and anatomical measurements were compared to assess the accuracy of the CT representation of osseous structures. Nine structures were examined: the optic canal; the superior orbital fissure; the foramen rotundum; the foramen ovale; the foramen spinosum; the foramen Vesalii (venosum); the carotid canal; the internal auditory canal, and the hypoglossal canal.
