    Can the Human Tail Cause Arteriovenous Hemangioma?
    (Karger, 2021) Aydin Ozturk, Pinar; Kaya, Seyhmus
    Introduction: Human tail is a congenital, benign anomaly in which a protrusion in the lumbosacrococcygeal caudal region is covered with skin. Arteriovenous hemangioma is a benign vascular lesion that may be congenital or acquired. We present a case in which a human tail was present with pathological findings of arteriovenous hemangioma. Case Report: A 6-month-old girl was born with a curved tail-shaped protrusion along her waistline. The distal portion was purple and had a solid consistency; the proximal portion was of normal skin color and had a soft consistency. No other abnormality was observed in the spinal area. Microscopic examination revealed congested, proliferated vascular structures in the fibrous stroma distally located under the multilayered squamous epithelium. In the proximal area, mature lipomatous tissue was observed. The lesion was diagnosed as arteriovenous hemangioma. Conclusion: Our patient presented with the classic human tail appearance at an early age and in the lumbosacral region. Because of the pathological findings, surgery for the congenital anomaly had to be performed with extra caution.

    Pediatric Orbital Roof Intradiploic Meningioma Operated by Eyebrow Incision
    (Karger, 2020) Aydin Ozturk, Pinar; Yilmaz, Tevfik; Ozturk, Unal; Aydin, Kamuran
    Introduction: Primary intradiploic meningiomas account for <1% of all osseous calvarial lesions and are categorized as bone tumors. They are frequently observed in the frontotemporal region of the calvarium, anterior cranial fossa, and orbit. We present a case of intradiploic meningioma of the orbital roof, which is rarely observed in the pediatric age-group; it was surgically treated with a unique minimally invasive approach. Case Presentation: A 16-year-old male with chief complaints of headache on the right side for approximately 1 year was presented to our clinic. Cranial MRI revealed an intradiploic mass with homogeneous, hypointense contrast patterns on the T1W and T2W images of the right orbital roof. A skin incision was made through the right eyebrow, and the frontal sinus anterior wall was opened by craniotomy. Gross total resection was achieved by reaching the tumor present in the orbital roof. The mass was characterized as psammomatous meningioma by a pathological examination. Discussion/Conclusion: In cranial oncologic surgery, lesion localization and possible pathological diagnosis are essential for the determination of the correct surgical technique. In particular, in pediatric cases, selecting a method that will reduce the need for transfusion, shorten the surgical time, minimize the chances of facial deformity, and facilitate postoperative care will ensure compliance with the correct and appropriate treatment process.
