RESUMO
Intravascular lymphomatosis (IVL) is a rare, malignant B- or T-cell lymphoma with remarkable affinity for the endothelial cells of small vessels, particularly within the skin and central nervous system. It is a disease that mimics several neurological disorders, particularly those of cerebrovascular ischemic origin. The prognosis is generally poor, with a rapidly fatal outcome. As a result the diagnosis is often made at post-mortem. We report a rare case of a 73-year-old patient with IVL complicated by intracerebral haemorrhage. In literature two cases of systemic IVL complicated by intracerebral haemorrhage have been reported, but they presented initially with a disseminated intravascular coagulation (DIC). This is the first case of brain IVL complicated by intracerebral haemorrhage not associated to DIC. Increasing awareness of this disease as a differential diagnosis to a common clinical presentation may lead to more opportunities to evaluate new diagnostic and treatment approaches.

Glomus tumor, also known as glomangioma, is a neoplasm derived from cells of the neuromyoarterial glomus or glomus body. We report a case of glomus tumor of the lung arising in the left lower lobe, incidentally found in a patient who underwent right bilobectomy for a carcinoma localized in the right upper lobe.

Spinal cavernous angiomas are rare vascular malformations occurring mainly in the vertebral body with or without an extradural extension. Only 3-5% of these lesions are entirely located in the spinal canal where they can occupy an extradural, intradural-extramedullary or intramedullary position. We present a 75-year-old woman with signs and symptoms of multiple lumbar radiculopathy. The lumbosacral MRI showed an intradural cauda equina lesion with heterogeneous contrast enhancement that was subsequently radically removed through an L3-L4 laminectomy. The microscopic appearance was suggestive of cavernous angioma with intraneural growth. Clinical, radiological, and surgical features of this unusual lesion (to date, only 12 cases are reported) are discussed.
