The vein of Galen aneurysmal malformation (VGAM) is a rare cerebral arteriovenous malformation that can be life-threatening if not diagnosed and treated early. VGAM usually presents in the neonatal period with high-output cardiac failure. We report the case of a full-term male neonate who presented with respiratory distress, and a fontanel bruit soon after birth. A chest radiograph revealed marked cardiomegaly. Transthoracic echocardiography showed dilatation of all four cardiac chambers and a patent ductus arteriosus. Transfontanellar doppler ultrasound and brain computed tomography confirmed the diagnosis of a VGAM. Clinical worsening took place despite aggressive hemodynamic and ventilatory support. The patient's Bicêtre Neonatal Evaluation Score for embolization was 2. Endovascular treatment could not be performed. The patient regretfully passed away. VGAM should be considered in the differential diagnosis of neonatal congestive heart failure with a structurally normal heart. Early diagnosis and treatment improve prognosis considerably.

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.

ERDHEIM CHESTER disease (ECD) called also non-Langerhans Histiocytosis, is a rare illness, which can present various unusual clinical aspects. It is a Histiocytosis characterized by an infiltration of various tissues and organs, bones, retroperitoneum, pleuro-pulmonary sites, skin, and central nervous system. The most frequent central nervous system manifestations of ECD are diabetes insipidus, cerebellar syndromes, orbital lesions, and extra-axial masses involving the dura and here we report a rare case with spinal cord compression on the context of ERDHEIM CHESTER disease. Our work highlights another different clinical, radiological and pathological manifestation associated with ECD that should be considered.
