The authors describe a rare case in which an infundibular dilation at the origin of a circumflex branch of the P1 segment of the posterior cerebral artery caused subarachnoid hemorrhage. Wrapping was performed by a subtemporal approach in the delayed stage. At the time of surgery, the rupture point was found in the infundibular dilation.

Background And Objectives: Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are common causes of cicatricial alopecia. While several studies have demonstrated the usefulness of non-invasive imaging methods such as reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) for the diagnosis of scarring alopecia, this study aimed to identify characteristic features of cicatricial alopecia in LPP/FFA using line-field confocal OCT (LC-OCT).
Patients And Methods: Fifty-one patients (26 LPP, 24 FFA, 1 LPP and FFA) were prospectively analyzed with LC-OCT at three defined locations on the scalp: (1) scarring area = lesion, (2) scar-hair boundary = transition zone and (3) healthy area for the presence of the following pre-defined criteria: no hair follicles left, destructed hair follicles, dermal sclerosis, no rimming of the dermal papillae, epidermal and dermal inflammatory infiltrate, infundibular hyperkeratosis, dilated blood vessels, hypervascularization, melanophages, epidermal pigment incontinence.

Objective: Outpouchings, particularly those originating from the posterior communicating artery off the internal carotid artery (Pcom-Ops), are often unable to be categorized definitively as aneurysms or infundibula resulting in frequent clinical imaging and follow-up. We aimed to investigate potential correlations between growth and rupture rates and easily definable imaging characteristics in Pcom-Ops.
Methods: We analyzed CT and MR imaging of Pcom-Ops identified in a case series of patients seen between 2007 and 2022.

The median sacral artery (MSA) is the single unpaired dorsal branch of the abdominal aorta. The present case describes the relatively unusual origin of the median sacral artery in common with the fourth pair of lumbar arteries via a common trunk in a 74-year-old males' cadaver. Unusual common trunk is prone for iatrogenic injury in surgeries of the lumbar and pelvic region.

Five dogs and two cats with a diagnosis of double-chambered right ventricle or primary infundibular stenosis were referred to undergo a combined cutting balloon and high-pressure balloon technique. At admission five cases were asymptomatic, one had a history of syncope and one had signs of right-sided congestive heart failure. Each patient underwent a complete transthoracic echocardiogram, thoracic radiographs, an angiogram and the combined interventional procedure.
