Abstract A mucocele refers to an appendix that has dilated due to progressive accumulation of mucus within its lumen. Appendiceal mucocele is a rare cause of an acute abdomen. They represent 0.2-0.7% of all appendix specimens. LAMN account for less than 0.3% of appendicectomy specimens.  We present a 38 year old man with an acute RIF’s pain who went on to have CT scan which revealed a mucocele of appendix but did not show any features of perforation or pseudomyxoma peritonei. He had a laparoscopic converted to open appendicectomy. The proximal 2 cm of appendix was oedematous but normal calibre. Histology revealed a low grade appendiceal mucinous neoplasm (LAMN) that was completely excised.  The mucocele of the appendix was first described by Rokitansky in 1842. Appendix mucocele may come as a consequence of obstructive or inflammatory processes, cystadenomas or cystadenocarcinomas. Appendiceal mucinous neoplasms commonly presents in the sixth decade of life and our patient was much younger in comparison. Several literatures suggest the value of preoperative CT imaging in obtaining diagnosis and also in planning further treatment. Appendicectomy or a right hemicolectomy is treatment of choice based on presence or absence of following factors 1. Perforated mucocele 2. Involvement of the base of the appendix. 3. Positive lymph nodes of mesoappendix and ileocolic. Patients with malignancy or pseudomyxoma peritonei are likely to require cytoreductive surgery, heated intraoperative intraperitoneal chemotherapy, early postoperative intraperitoneal chemotherapy.

Ependymomas are common spinal lesions, with the vast majority arising in an intramedullary location. Several cases have been described in the literature of ependymomas in an intradural, extramedullary location. The authors present a case of a 56-year-old female who presented with several weeks of lower back pain and weakness. MRI revealed an intradural, extramedullary enhancing mass at L1-L2. The mass was successfully resected surgically. Pathologic evaluation revealed a low grade glioma with components of both ependymoma and pilocytic astrocytoma with MUTYH G382D mutation. Extramedullary ependymomas are very rare tumors. To the authors’ knowledge, this is the first case of ependymoma/astrocytoma collision tumors described in an extramedullary location.
