“…Although many studies have pointed out that the complex embryological development of the MMA may lead to numerous variations, 13,14 we failed to find any description in the medical literature that presents data similar to ours and thus could be directly confronted with our results. However, we believe that the explanation for the formation of this intermittent bony tunnel may be related to the embryological association that exists between the skull/dura mater and the MMA.…”

The knowledge of certain anatomical variations is fundamental and any surgeon who operates without that knowledge may encounter difficulty during surgery. In this context, there is the middle meningeal artery (MMA) which also engenders considerable clinical interest due to its location. The MMA is predominantly periosteal, irrigating the bone and dura mater. It enters the floor of the middle cranial fossa through the foramen spinosum, travels laterally through a middle fossa bony ridge, and curves anteriorly over the upper-greater wing of the sphenoid where it divides into parietal and frontal branches at a variable point. Occasionally, the distal segment of the frontal branch may pass through a bony tunnel of variable size. To the best of our knowledge, there is no evidence in the current literature on the incidence of this rare bony tunnel. Therefore, we decided to investigate the incidence of this bony tunnel in 85 dry skulls of adults (both genders) belonging to the didactic collection of the Human Anatomy Laboratory of the Universidade de Santa Cruz do Sul, Brazil. All the skulls were examined bilaterally for the presence or absence of the bony tunnel associated with the distal segment of the frontal branch of the MMA. Of the 85 skulls analyzed, the bony tunnel was present on the right side in 1.18% and on the left side in 5.88% (p = 0.045). Thus, in the studied sample, there was a significant tendency for this bony tunnel to be formed on the left side.

“…The branches of the normal adult MMA includes a supraorbital branch to the orbit, as well as smaller branches to the trigeminal ganglion, the petrosal branch, and the superior tympanic artery. 2 …”

“…Waga et al 19 published a single case of basilar-MMA anastomosis in a 47-year-old man during angiography. Recently, Kuruvilla et al 2 described the first angiographically documented case of the anomalous origin of the MMA from the posterior inferior cerebellar artery. According to the authors, the posterior inferior cerebellar artery-MMA anastomosis can be obscured by arteriovenous malformations and vascularized tumors involving the dura of the posterior cranial fossa.…”

Originating from the maxillary artery, the middle meningeal artery (MMA) is predominantly periosteal irrigating the bone and dura mater. It enters the floor of the middle cranial fossa through the foramen spinosum, travels laterally through a middle fossa bony ridge, and curves over the previous upper-greater wing of the sphenoid, where it in a variable point is divided into frontal and parietal branches. The complex sequence of the MMA development gives many opportunities for variant anatomy. In a Caucasian cadaver skull of an approximately 35-year-old individual belonging to the didactical collection of the Laboratory of Human Anatomy at the University of Santa Cruz do Sul, Brazil, it was noted that the right foramen spinosum has an abnormal shape. In this report, we discuss an abnormality of the foramen spinosum due to a variation in the trajectory of the MMA. Thus, the present study shall be important for health sciences and those who have some interest in pathologies associated with the MMA.

“…There are many PICA variants, including persistent trigeminal artery, duplicate origin, fenestration, and anterior inferior cerebellar artery (AICA)-PICA variant. An extradural origin of the PICA from the VA has been reported in 5%–18%, usually at the C1 and C2 levels, and there have also been reports of the PICA arising from numerous other vessels [1] , [2] , [3] , [4] . However, the PICA originating from the ascending pharyngeal artery (APA) has been very rarely reported.…”

Anomalous origin of the posterior inferior cerebellar artery from the jugular branch of the ascending pharyngeal artery: A case report

The posterior inferior cerebellar artery usually arises from the vertebral artery and has several variants. The posterior inferior cerebellar artery originating from the jugular branch of ascending pharyngeal artery has rarely been reported. A 63-year-old woman underwent cerebral magnetic resonance imaging and magnetic resonance angiography; the latter incidentally revealed an anomalous origin of the posterior inferior cerebellar artery. We report and discuss the neuroimaging findings in a patient with this anomaly. Determining the origin of the posterior inferior cerebellar artery is an important factor in planning surgical and endovascular treatment strategies for skull base disorders.
