Key Clinical Message:Subarachnoid Haemorrhage (SAH) represents a critical medical emergency that can result from either a traumatic head injury or the spontaneous rupture of an aneurysm. Timely diagnosis and carefully planned interventions are of paramount importance in managing this condition to enhance clinical outcomes. Additionally, it is crucial for healthcare professionals to be well-informed about the associated risk factors and potential complications that may arise during the course of this emergency. We present the case of a 16-year-old female patient who developed subarachnoid haemorrhage due to the rupture of a berry aneurysm. Both clinical and imaging diagnostics confirmed the presence of a ruptured berry aneurysm and subarachnoid bleeding. Subsequently, the patient underwent successful endovascular coiling, leading to her recovery.While extensive literature underscores the effectiveness of endovascular coiling in treating ruptured aneurysms, its utilization is less common in the developing world. This can be attributed to limited resources and inadequate training of physicians in this specific procedure. Given the widespread occurrence of subarachnoid haemorrhage, it is imperative that healthcare systems in developing countries are adequately equipped to offer minimally invasive treatments that can improve clinical outcomes. Furthermore, our case report highlights a significant clinical association between connective tissue disorders and the occurrence of ruptured berry aneurysms. This underscores the need for further research into this particular association.
