Malignant Thymoma with Brain Metastasis

Malignant thymoma with metastasis associated with paraneoplastic myasthenia gravis.

We describe a patient who initially presented with a mixed thymic tumor and developed myasthenia gravis 8 years following thymectomy with recurrence of metastatic disease. Metastasis to the pleura, mediastinum, and cervical spine was identified with a positron emission tomography scan when this patient presented with recurring pneumonias and atrial fibrillation. The presentation and diagnosis w...

Thymoma with Sacral Metastasis

Thymomas are the most common type of mass found in adult anterior mediastinal masses. Thymomas typically metastasize to the ribcage because of their slow growth and affinity for local invasion. Far metastases are rare, with the brain as the most commonly metastasized area. Bone metastases of thymomas are usually observed in the calvarium. A 60-year-old patient, who presented with metastatic mas...

Brain Metastasis from Invasive Thymoma Mimicking Intracerebral Hemorrhage: Case Report

A 55-year-old man with an 8-year history of invasive thymoma presented with sudden onset of left hemiparesis. Computed tomography (CT) and magnetic resonance (MR) imaging showed a right frontal lobe intracerebral hemorrhage and the possibility of brain metastasis could not be rejected. The patient underwent removal of the hematoma. Histological examination showed brain metastasis from invasive ...

Malignant Meningioma with Lumbar Spinal Metastasis (a case report)

Meningioma is considered as a benign central nervous system tumor that accounts for approximately 18% of all brain tumors. About 5% of meningioma tumors are malignant and have more aggressive clinical signs and worse prognosis compared to benign tumors. Extracranial metastasis of meningioma is rare but in the case of occurrence, it is more prevalent in lung, liver and lymph nodes. Osseous metas...
