“…10 The anatomical relationship of the DVS to the emissary veins, dural sinuses, meninges, skull base, calvarial bone, and skin, and its role in pathophysiological conditions such as air embolism during surgery have been described. 10,15,17,18,47,50,56,66 However, its potential role in other pathological conditions such as venous sinus thrombosis, 20 cancer metastases, 71 infection dissemination, intracranial hypertension, 40 hydrocephalus, 31,44,48 intracranial hematomas, 4,23,66 craniosynostoses, tumors, and pediatric neurosurgical conditions 32,35,37,39,42 is poorly understood. Some authors have proposed that the connections between arachnoid granulations and the DVS and dural sinuses might function as valves to control blood flow between the cranial diploë and sagittal sinus and between the cerebral veins and dural sinuses.…”

Object There are few systematic investigations of the dissected surgical anatomy of the diploic venous system (DVS) in the neuroanatomical literature. The authors describe the DVS relative to different common neurosurgical approaches. Knowledge of this system can help avoid potential sources of unacceptable bleeding and may impact healing of the cranium. Methods Using a high-speed drill with a 2-mm bit, the authors removed the outer layer of the compact bone in the skull to expose the DVS in 12 formalin-fixed cadaver heads. Pterional, supraorbital, and modified orbitozygomatic craniotomies were performed to delineate the relationship of the DVS. Results The draining point of the frontal diploic vein (FDV) was located near the supraorbital notch. The draining point of the anterior temporal diploic vein (ATDV) was located in all pterional areas; the draining point of the posterior temporal diploic vein (PTDV) was located in all asterional areas. The PTDV was the dominant diploic vessel in all sides. The FDV and ATDV could be damaged during supraorbital, modified orbitozygomatic, and pterional craniotomies. The anterior DVS connected with the sphenoparietal and superior sagittal sinus (SSS). The posterior DVS connected with the transverse and sigmoid sinuses and was the dominant diploic vessel in all 24 sides. Of all the major diploic vessels, the location and pattern of distribution of the FDV were the most constant. The parietal bone contained the most diploic vessels. No diploic veins were found in the area delimited by the temporal squama. Conclusions The pterional, orbitozygomatic, and supraorbital approaches place the FDV and ATDV at risk. The major anterior diploic system connects the SSS with the sphenoparietal sinus. The posterior diploic system connects the SSS with the transverse and sigmoid sinuses.

“…In the present case, MRI showed the sinus pericranii as a homogeneous intensity signal, while the previous reports described the epicranial mass as a region of mixed intensity that was caused by a turbu lent flow [2,7,8], Classification of sinus pericranii has been well re viewed in the literature [1,2,5]. Physiopathologically, sinus pericranii is divided into two types: closed and drainer types [6]. The former consists of a closed system in which the blood comes from and returns to the intra cranial sinus.…”

We report an 11-year-old boy with a sinus pericranii. Magnetic resonance images demonstrated a small hole in the cranium underneath the subcutaneous mass. Magnetic resonance angiography (MRA) with sequential two-dimensional time-of-flight (2D-TOF) method demonstrated that the venous flow via the sinus pericranii was directed from the intra- to the extracranial venous system (the drainer type). This was confirmed by a combination of conventional cerebral angiography and percutaneous sinography. We advocate that both the correct diagnosis and classification of sinus pericranii can be established with a combination of current noninvasive neuroradiologic studies, especially for the pediatric age group. MRA with the 2D-TOF method is useful in the assessment of this venous anomaly.

“…17 Some authors suggest an acquired pathophysiology because of the development of SP after head trauma, skull fracture, emissary vein tear, or birth trauma. 4,11,13 However, the constant association with other vascular anomalies 7,12,14 (for example, angiomas, 18 aneurysmal malformation of an internal cerebral vein, 12 subcutaneous venous cavernoma) supports a congenital cause such as failure of regression of the venous plexus between the periosteum and dura during early brain development or failure of the closure of intracranial sutures. 10 The presence of endothelial lining defines a congenital SP and distinguishes it from the acquired type.…”

“…10 The presence of endothelial lining defines a congenital SP and distinguishes it from the acquired type. 7 Sinus pericranii affects mainly young people, 80% of cases occurring in patients younger than 40 years of age. It appears to occur with approximately equal frequency in males and female, although males may be more affected due to a higher incidence of head injury.…”

Sinus pericranii (SP) is an uncommon and usually asymptomatic communication between intra- and extracranial venous drainage pathways in which blood flow can circulate bidirectionally through abnormal dilated veins through a skull defect. Diagnosis and evaluation of the venous drainage pattern is important if treatment is contemplated. Cerebral angiography with the use of Dyna CT can be helpful in the diagnosis of SP and its relationship with the skull defect. The authors report what is, to the best of their knowledge, the first case of SP treated by means of endovascular embolization with Onyx.
