MB should be considered as a differential diagnosis of a lesion in the CPA. The treatment and outcome of CPA MBs are similar to cerebellar MBs.

Introduction Medulloblastoma (MDB) often causes signs and symptoms of elevated intracranial pressure (ICP) with imaging findings of mass lesion. Here, we report a case of MDB who initially presented with clinical features imitating idiopathic intracranial hypertension (IIH) and Chiari I malformation (CIM). Case presentation A 19-year-old man had clinical symptoms of elevated ICP without mass lesion on imaging. He was initially diagnosed with IIH and CIM, which underwent shunt surgery and posterior fossa decompression. Later on, he had recurrent symptoms, and the new imaging revealed the development of MDB in the right cerebellar hemisphere. After tumor resection, the patient rapidly deteriorated with spinal metastases. Discussion and conclusion Management of the coexistence between IIH and CIM in patients with rising ICP is complicated. MDB is one of the aggressive malignant brain tumors showing a wide range of imaging features, including non-enhancing mass. Therefore, recognizing the possibility of brain tumors mimicking IIH or CIM is crucial.

The endometriosis in the Canal of Nuck is a rare condition. Most patients exhibited groin swelling but this case present with a rare condition which is suprapubic pain for 2 years. This case is a 34-year-old healthy woman had developed chronic intermittent right suprapubic pain for 2 years. Physical examination revealed a 2-cm. Reducible mass at right suprapubic area. MRI was performed and the result showed a 2.7 × 1.3 × 4.9 cm-size multiloculated cystic mass located near the round ligament of the uterus which was consistent with a Nuck's canal cyst. The definitive treatment was done by excision of mass.
