Introduction. Although there are lots of varieties of aorta arch, they seem to appear relatively rarely. Anomalies of aortic arch departures are mainly concerned with its location, course, the place of departure and number of its main branches. However, they warrant attention due to their importance in operative, diagnostic, and endovascular procedures. Aim. We want to present here a case of a female cadaver with rare aortic arch origin of the left vertebral artery. The aim of this article is to complete the frame of anomalies in aortic arch and to explore rare variability shown in this specific case. Description of the case. The present report describes an anomalous case of the left vertebral artery arising from the aortic arch between the left common carotid artery and the left subclavian artery in a female cadaver during dissection in an anatomical laboratory. Aortic origin of the vertebral artery is a rare anatomic variant. Conclusion. Thorough knowledge of anomalous origin is important for patients who undergo operation of an aortic arch or inferior part of the neck. Normally, the vertebral artery arises from the first part of the subclavian artery on both sides.

Introduction and aim. Granulomatosis with polyangiitis (GPA), formerly known as Wegener’s granulomatosis, presents a formidable challenge in the realm of autoimmune diseases. Granulomatosis, characterized by vasculitis and granuloma formation, exhibits diverse clinical manifestations. The rarity of GPA is evident, with an estimated incidence between 0.4 and 11.9 cases per 1 million person-years. The aim of this report is to show the complex diagnostic challenges inherent in GPA, demonstrating the diagnostic process from initial symptoms. Description of the case. This case report unfolds the diagnostic journey of a 52-year-old Caucasian male. The presented case, initially suspected as a respiratory infection, led to a comprehensive investigation owing to persistent symptoms, abnormal blood counts, and elevated inflammatory markers. This narrative aims to depict the patient’s diagnostic journey. Key diagnostic tools include ANCA testing, imaging studies, and tissue biopsy. Pulmonary nodules, lymphangitic changes, and renal involvement culminating in a GPA diagnosis confirmed by positive ANCA and anti-PR3 antibodies. The successful management of this case involved a tailored therapeutic regimen, including cyclophosphamide and methylprednisolone, addressing both vasculitic and renal components. Conclusion. This case contributes to the understanding of atypical presentations of GPA, emphasizing the importance of a holistic and dynamic diagnostic approach.
