AI Article Synopsis
- Non-traumatic true superficial temporal artery (STA) aneurysms are extremely rare, with only about 63 reported cases, and often lack detailed pathological descriptions.
- The case study presented involves a 31-year-old man with a pulsating lump on his temple, diagnosed as a STA aneurysm via Doppler ultrasound, and confirmed with 3D CT angiography.
- Clinical findings emphasize the importance of imaging to assess for additional vascular issues and highlight the potential risk of hemorrhagic rupture if left untreated, aiming to enhance awareness and guidance for evaluation and management of similar cases.
Article Abstract
Introduction And Importance: Non-Traumatic True superficial temporal artery (STA) aneurysm is a very rare condition. Only around 63 cases have been reported in the literature up to date [1]. Unfortunately, most of published cases lack proper pathological description. Moreover, researchers found that 12.5 % of true STA aneurysms were associated with risk of co-existing other sites' vascular lesions [2,3]. In this paper, we are going to describe case of Non-traumatic true STA aneurysm and illustrate detailed pathological description.
Case Scenario: A 31-year-old man presented with a painless lump over the left temporal region of one year's duration. The lump was 2 × 2 cm expansile and pulsated. Doppler ultrasound confirmed the diagnosis of STA aneurysm and 3D CT angiography used to rule out other vascular lesions. Aneurysmectomy was performed. Histologic examination revealed three layer of the arterial wall.
Clinical Discussion: Pulsatile swelling over the temporal region is the common presentation of Non-Traumatic True STA. Further evaluation by 3D CT angiography is crucial to rule out other sites' aneurysms. In untreated NT STA there will be 1.6 % risk of hemorrhagic rupture [1].
Conclusion: To the best of our knowledge, this is one of few case reports with detailed histologically finding verified true (spontaneous) STA aneurysm. This case report sought to raise the awareness for proper evaluation of head swelling along with management interventions and follow up.

Background: Giant non-traumatic and non-iatrogenic cranial vault defects are poorly studied due to their rarity. Therefore, diagnosis and analysis of their causes are difficult. In available literature, we found only 4 cases of giant pericranial sinus accompanied by extensive cranial vault defects.

Background: The distal end radius's bony anatomy in relation to three variables-Radial Inclination, Volar tilt, and radial height-has been discussed commonly in the adult population and is not very well defined in the growing skeleton. In children aged 8-16 years old, we measured the osseous distal end radius according to radiography standards. The research comprised 130 patients, 65 males and 65 females aged 8-16.

Spontaneous coronary artery dissection (SCAD) is a non-traumatic, non-atherosclerotic layering of the coronary artery wall due to the presence of a subintimal hematoma or an intimal tear with the creation of a false lumen that compresses the true lumen and restricts or obstructs the flow. Patients with SCAD and preserved coronary flow are treated conservatively according to the general recommendations. However, percutaneous coronary intervention should be considered in patients with artery occlusion and/or refractory ischemia.

They are divided into two categories: true cysts with epithelial lining, and false pseudocysts without epithelial lining, which is more common than true cysts. We describe here a case of a non-traumatic splenic pseudocyst in a healthy 29-year-old male patient, who presented with left upper quadrant abdominal pain.
