Due to the risk of rupture, treatment of the pseudoaneurysms of splenic artery is considered as a priority in the management of pancreatitis. While endovascular embolization is an established minimally invasive and effective technique for the treatment of splenic artery pseudoaneurysms, however, in some cases endovascular embolization may not be feasible, owing to the difficulties in accessing the distal small pseudoaneurysms or due to financial constraints. In such a scenario, percutaneous image guided direct puncture and embolization of the pseudoaneurysms is a valuable option. While most of the previous publications have reported on the use of n‑butyl cyanoacrylate, coils and thrombin for percutaneous embolization of splenic artery pseudoaneurysms, however, these agents may not be easily accessible to many health facilities in emergency situations and their cost may limit their use.

They might be challenging to detect and cure. This article recounts the example of a 23-year-old man who suffered from regular headaches and visual issues. During the first MRI, a solid cystic tumor in the pineal area was identified, creating obstructive hydrocephalus by squeezing surrounding brain regions. A low-grade glial tumor was discovered during the operation, which included partial tumor excision and an endoscopic third ventriculostomy. However, follow up imaging revealed a rapid recurrence requiring external ventricular drainage and a second craniotomy. Following the second surgery, histopathology confirmed pineoblastoma, demonstrating the aggressive character of the tumor. Postoperative imaging showed persistent illness despite these measures, requiring the implementation of a comprehensive treatment strategy. The multidisciplinary team suggested craniospinal irradiation (35 Gy in 21 fractions) followed by lesion boost (19.8 Gy in 11 fractions), using VMAT (Volumetric modulated Arc therapy) technique, along with concurrent chemotherapy followed by adjuvant chemotherapy. This case illustrates the difficulties in identifying and managing recurrent pineal tumors, including the need for appropriate adjuvant treatment, surgical constraints, and recurrence concerns. It provides crucial information regarding the challenges of treating aggressive brain tumors and emphasizes the need for interdisciplinary care to achieve the best results. This is a rare case of Central Nervous system recurrent tumor, which was earlier thought to be a low grade pineal tumor but later turns out to be high grade, Pineoblastoma in a young adult male.
