Primary lymphoma of the cerebellopontine angle (CPA) is rare and uncommon in the central nervous system, accounting for approximately 0.2-2% of all brain tumors. To our knowledge, there have only been 32 cases reported worldwide so far. Here, we report a rare case of B-cell lymphoma in a 56-year-old woman who presented with seizure, dysphagia, and dizziness and showed a lesion involving the left CPA, right frontal horn and septum pellucidum on magnetic resonance imaging (MRI). The primary diagnosis was metastatic tumor; however, Stereotactic biopsy on left CPA lesion was done, and the histological features confirmed the diagnosis of B-cell malignant lymphoma. The patient was treated with chemotherapy, with complete resolution of symptoms after the first chemotherapy session.
Background: The intracranial mycotic aneurysm is known to be a rare complication of infective endocarditis and it is more clinically challenging to get this diagnosis right when it happened to be in a patient without a past medical history of heart diseases. We report a documented case of mycotic aneurysm revealed by isolated left hemiparesis and our management with the collaboration of the cardiology department. Case Description: A 48-year-old male patient with a history of teeth loss, a chronic smoker presented with sudden heaviness in the left upper and lower limbs. No fever. Physical examination revealed a left hemiparesis of 3/5 on the muscle tone scale without the stiffness of the neck. The CT-Scan and the MRI conclude of subarachnoid and cerebral hemorrhage with right temporal hematoma being most probably a vascular malformation. The cerebral arteriography concluded of a right Sylvian mycotic distal aneurysm in the M4 segment. Transesophageal echocardiography was performed and concluded of infectious endocarditis with mitral and aortic valvular disease grade II. Positive blood culture for staphylococcus coagulase-negative. The patient was managed with antibiotic therapy and clinically stable after 28 days. He was then transferred to the cardiology department for follow-up. Six (6) months later a CT-angiography was done for a check-up and shows no further changes in the aneurysm. The patient underwent surgery, two (2) months later, for clipping the aneurysm because the aneurysm did not regress in size. The aneurysm was then excluded with an eventless post-operative period, confirmed by controlled cerebral arteriography. The patient was discharged five (5) days later and he is doing well.

Pituitary abscess gland is an uncommon lesion on sellar region. Clinical diagnosis is not easy to make and it is difficult to make difference from other pituitary lesions on clinical and sometimes on Neuroimaging. This pathology is characterized by vague symptoms, headaches, generalized tiredness and hypopituitarism manifestations. A 35-year-old woman was admitted to neurosurgery with complaints of headaches and blurred vision. MRI of the head revealed a suprasellar mass that was centrally hyperintense lesion on T2-weighted images with peripheral hypointensity. Treatment of the lesion of this lesion pituitary area through a transsphenoidal approach and spectrum antibiotic therapy with ceftriaxone metronidazole and vancomycin for 6 weeks. The patient continues to have pituitary insufficiency and is treated with oral hydrocortisone. After the diagnosis, the surgery and antibiotics should be commenced rapidly. Our aim is to report this rare case and to show how sometimes it is difficult to make diagnosis and clinical features vary mimicking other pituitary lesions before pre-operative and how to manage pituitary abscess gland. The outcome is usually good with proper treatment.
