“…Demonstration of a proximal hypoplastic BA below the abnormal communication, with enlargement above, has been considered an ancillary finding of PPTA (10). According to the hemodynamic of the posterior circulation distal to the connecting point between the PPTA and the BA, the BA can show a varying degree of hypoplasia of the proximal BA with or without hypoplasia of vertebral arteries (11).…”

“…In our case, the ipsilateral posterior communicating artery was absent and the ipsilateral vertebral artery was hypoplastic. Athale et al have described a proximal hypoplastic basilar trunk below the anastomosis, which enlarges to a more normal caliber above the aberrant communication, as an important ancillary sign of PTA and have opined that this should be looked for on routine MR studies in cases with suspected carotid‐basilar anastomoses 10 . In our case, the basilar trunk below the anastomosis was smaller in caliber than the post‐anastomotic segment.…”

Persistent trigeminal artery (PTA) is the most frequent type of persistent primitive carotid-basilar artery anastomoses. Persistent trigeminal artery is usually associated with small or absent posterior communicating artery (Pcom). It may also be associated with hypoplastic vertebral and basilar arteries. Patients may present with symptoms related to hypo-perfusion of posterior circulation or microembolization from carotid artery to posterior circulation. We are presenting a 60-year-old who had recurrent episodes of vertigo and parasthesia, in whom MR angiography revealed a medial, Saltzman type 1 PTA on the left with absent ipsilateral Pcom, duplicated ipsilateral superior cerebellar artery, hypoplastic A1 segment of contralateral anterior cerebral artery (ACA), azygous ACA and hypoplastic ipsilateral vertebral artery.

“…Athale et al reported two women (46 and 19 y old), finding the classic appearance of persistent trigeminal artery on MR imaging [8]. This finding also was used as an ancillary sign of this anomaly in subtle cases of persistent fetal carotid-basilar artery anastomoses.…”

Magnetic Resonance (MR) uses many exam of medical image field. In this case report, we found an interesting case. We did not call it as patient because she did not present any symptoms, thus we call it as subject. Natural cerebral vascular deficiency was seldom to be reported due to subject does not present any obvious symptoms when subject is health or young. Hope that this case report would increase we know more about the congenital part cerebral vascular deficiency. A 36 y old female, who come to our hospital for advanced medical health examination. On the regular radiology exam, the MRI showed she has a congenital part cerebral vascular deficiency on December in 2013. In general, main cerebral artery deficiency would cause some impact on physiological, however, its seemly does not affect her in daily or intelligent working, or we still not know would it affect to human. This case report showed a young women persistent hypoglossal artery was missing. We should continuous follow the subject by regular medical health examination. For her, we can prevent further congenital caused injuries. It also added a rare case of Taiwanese in medical imaging academic field.
