“…However, there was a prominent artery arising from the cavernous segment of the left internal carotid artery, running posteriorly and terminating at a localised collection of capillaries with adjacent contrast staining (arrow). The location, course and size of this vessel is in keeping with a prominent meningohypophyseal artery (11) leading to a region of abnormal appearing blood vessels which show a characteristic 'tumour blush' angiographic pattern. The normal meningohypophyseal artery is often too small to be visualised on angiography.…”

The Singapore Health Services cluster (SingHealth) radiology film archives are a valuable repository of local radiological cases dating back to the 1950s. Some of the cases in the archives are of historical medical interest, i.e. cerebral angiography in the workup of patients with hemiplegia. Other cases are of historical social interest, being conditions seen during earlier stages of Singapore’s development, i.e. bound feet. The archives form a unique portal into the development of local radiology as well as the national development of Singapore. A selection from the archives is published in 2020 in commemoration of the 20th anniversary of the formation of SingHealth, the 55th National Day of Singapore, and the 125th anniversary of the International Day of Radiology. This pictorial essay comprises cardiovascular, respiratory and neurological cases from the archives.

“…Normally, the MHT originates in the posterior genu of the cavernous ICA, with a diameter of approximately 1 mm, and then trifurcates into the MTA of Bernasconi-Cassinari, dorsal meningeal artery (the dorsal or lateral clival artery), and inferior hypophyseal artery ( 13 – 15 ). Ninety percent of MTAs are usually the terminal branch of the MHT, and 10% of them can arise directly from the cavernous ICA; 80% of MTAs originate as a single branch and as a bifurcation and trifurcation in 20% ( 16 ).…”

For tentorial dural arteriovenous fistula (TDAVF), the meningohypophyseal trunk (MHT), and medial tentorial artery (MTA) of Bernasconi-Cassinari are rarely used as transarterial paths to perform the successful endovascular treatment (EVT). We reported a TDAVF mainly fed by the MHT. Onyx-18 casting in the MTA of Bernasconi-Cassinari under the assistance of coil embolization in proximal MHT was performed. The technique was reported in case 1. At the same time, case 2 with a similar TDAVF was chosen as a control. In case 1, a 52-year-old man suffered a cerebellar hemorrhage. A TDAVF was confirmed by computed tomography angiography and digital subtraction angiography. The feeding arteries included the MHT, middle meningeal artery (MMA), and the artery of Wollschlaeger and Wollschlaeger of the superior cerebellar artery. The MHT and MTA of Bernasconi-Cassinari were hypertrophied. First, a Marathon microcatheter was placed in the MTA to wait for Onyx casting, and then an Echelon-10 microcatheter was placed in the proximal MHT trunk with an aneurysmal dilation to perform coiling to prevent Onyx reflux. Then, Onyx casting obliterated the TDAVF. Case 2 was a 75-year-old woman with TDAVF, and the MTA of Bernasconi-Cassinari was the main feeder. First, the TDAVF experienced incomplete EVT with Onyx casting via the MTA under no assistance of coil embolization in the proximal MTA. The second EVT had to be performed via MMA. Then, Onyx casting obliterated the TDAVF. Therefore, for selected TDAVFs with hypertrophied MHT, under the assistance of coil embolization in proximal MHT, Onyx casting via MHT can finish the complete EVT.

“…The tentorial artery is a small but reasonably constant channel which arises as a secondary branch of the meningohypophysial artery (Parlcinson 1964, Pribram, Boulter, McCormick 1966, and Wallace, GoIdberg, Leeds, and Mishkin 1967. This primary vessel, in turn, arises from the intraeavernous portion of the internal carotid artery.…”
