Primary non-Hodgkin's lymphoma of the sciatic nerve followed by localization in the central nervous system: case report and review of the literature.

OBJECTIVE AND IMPORTANCE: A unique case of primary non-Hodgkin's lymphoma of the sciatic nerve followed by multiple loci in the central nervous system is described. CLINICAL PRESENTATION: The lesion occurred in a 44-year-old immunocompetent man with a palpable mass in the left popliteal fossa and a 10-month history of progressive weakness and numbness of the left foot. The tumor was a diffuse large lymphoma of B-cell origin of an intermediate grade of malignancy according to the criteria of the International Working Formulation. INTERVENTION: Because diagnosis of the malignant lymphoma was performed on frozen section, resection of the nerve trunk was avoided. The patient was treated with radiotherapy and chemotherapy. At 6 months after the discovery, biopsy, and treatment of the sciatic nerve lymphoma, other lesions demonstrating the same histological features were observed in the central nervous system. The patient died 4 years and 2 months after presentation as a result of the central nervous system lesions and without clinical evidence of systemic extraneural localization. CONCLUSION: A review of the literature indicates that primary peripheral nerve lymphomas occur in the sciatic nerve. These cases, and the case described in our study, share common clinicopathological findings that justify discussing them separately as distinct entities.

Neuropathy caused by spontaneous intraneural hemorrhage: case report.

A case of ulnar neuropathy at the elbow produced by spontaneous intraneural hemorrhage in a patient with acquired immunodeficiency syndrome and thrombocytopenia is reported. Intraneural hemorrhage in patients with bleeding disorders occurs infrequently. It consists of acute intrafascicular bleeding, presumably producing very high elevations of endoneurial fluid pressure. The clinical features and treatment of this condition are considered, the pertinent literature is reviewed, and the involved pathophysiological mechanisms are discussed.

CT scan and surgical treatment of traumatic iliacus hematoma with femoral neuropathy: case report.

Iliacus hematoma should be suspected as the cause of femoral neuropathy in cases of minor trauma in teenagers, especially when the onset of paralysis is delayed and therefore an acute traction injury of the nerve is unlikely. In our 14-year-old female patient the condition followed minor trauma. In such cases CT scan should be performed. When this reveals a hematoma and the nerve lesion is rapidly progressing or complete, the hematoma should be promptly evacuated.

Traumatic amputation of the upper limb: replantation of the arm.

From 1970 to 1985, 13 patients were treated as a result of an upper limb traumatic sub-amputation. Three of them were younger than 15 years and another one was only 3 years old at the time of the trauma. All the elements involved in the treatment of the lesions are described. When it was possible, an end-to-end anastomosis was used for the repair of arteries and veins. Otherwise, when the loss of tissue was marked, a saphenous vein graft was used. The fracture was treated, when possible, with an intramedullary fixation, surely less traumatizing for soft tissues than a plate. The repair of the nerve was at times simultaneous at other times delayed. The followup has shown a good functional restoration of the limb and of the joints affected by the trauma and a normal development of the patients in terms of age.

The growth of cerebral cavernous angiomas.

The natural history of cavernous angiomas is poorly understood, and their growth has rarely been documented. We report three cases of cavernous angiomas that grew to large size in 6 years, 2 years, and 2 months, respectively. An initial computed tomographic scan disclosed no abnormalities in one patient and demonstrated two "minimal" lesions in the other two. The mechanisms of growth of these lesions are discussed; subsequent hemorrhages and capsule formation played a major role in their enlargement.

Blunt traumatic carotid dissection with delayed symptoms.

We describe five patients with blunt traumatic carotid dissection with delayed clinical presentation that varied from 2 weeks to 6 months. Four patients had severe head injury, and one patient had direct blunt trauma to the neck. Cerebrovascular symptoms developed in four patients. The fifth patient suffered loss of vision as a result of a concurrent giant intracranial dissecting aneurysm. Arteriography demonstrated a "string sign" in two cases and a cervical carotid aneurysm in three; two of the latter also had siphon occlusion, and one of these had a superimposed supraclinoid dissecting aneurysm. One patient was treated by thromboendarterectomy, one by aneurysmorraphy, another by carotid ligation, and the other two patients were treated medically. Mechanisms of injury, forensic problems, and therapeutic options are discussed.

Distal ulnar neuropathy from carpal ganglia: a clinical and electrophysiological study.

The clinical and electrophysiological observations in two cases of distal ulnar neuropathy from carpal ganglia are reported. In the first case, the ganglion was compressing the ulnar nerve just proximal to its division; in the second case, the ganglion was compressing the deep branch of the ulnar nerve just at its origin. In both cases, both axonal degeneration and segmental demyelination were present. A clinical classification of the compression syndromes of the deep ulnar branch is proposed.

A multidisciplinary approach for the treatment of metastatic brachial plexus neuropathy from breast cancer: neurosurgical, plastic, and radiotherapeutic.

A new approach for the treatment of metastatic brachial plexus neuropathy at the axillary level is described. This may be used in patients previously submitted to radical mastectomy followed by radiotherapy for breast cancer. The method consists of external neurolysis of the cords of the plexus, dissection and excision of the pathological axillary contents along with the overlying atrophic cutaneous and subcutaneous tissues, reconstruction of the axilla by the latissimus dorsi musculocutaneous flap, and finally early radiotherapy by high-dose radiation delivered to the entire area. The advantages of the procedure are briefly discussed.
