1/210. Splenic hemangiosarcoma with massive calcification.

    We present a case of large splenic hemangiosarcoma in a 40-year-old man associated with consumptive coagulopathy. Computed tomography showed radial calcification within the splenic tumor. On magnetic resonance imaging, T2 shortening represented a meshwork of calcification and surrounding fibrosis. The possibility of hemangiosarcoma should be considered when a large splenic tumor with massive calcification is noted. ( info)

2/210. bartonella henselae infection associated with peripapillary angioma, branch retinal artery occlusion, and severe vision loss.

    PURPOSE: To report atypical clinical features of bartonella henselae neuroretinitis treated with combination antibiotics. METHOD: Case report. RESULTS: A 20-year-old man with a positive B. henselae titer developed a unilateral neuroretinitis, a large peripapillary angiomatous lesion, branch artery occlusion with ischemic maculopathy, and vision loss that failed to improve with clindamycin. Treatment with doxycycline and rifampin led to rapid clinical improvement. The severe vision loss in this case is atypical. CONCLUSIONS: Ocular findings associated with B. henselae infection may include retinal angiomatous lesion and branch retinal artery occlusion. doxycycline and rifampin were successful in treating the infection.

3/210. Lobular capillary hemangioma of the cauda equina. Case report.

    This 56-year-old woman presented with a 1-year history of low-back pain, sciatica, and paresthesias in the right S-1 dermatome. On examination the patient was shown to have a right-sided Lasegue's sign, normal strength, hypalgesia in the right S-1 dermatome, and a slight diminution of the right achilles tendon reflex. magnetic resonance imaging revealed a 2-cm intradural enhancing lesion at the level of the L-4 vertebra. laminectomy of L3-L5 vertebrae was performed, and intradural exploration disclosed a blueberry-appearing tumor that was surrounded by an intense arachnoiditis and attached to the right S-1 nerve root. A cystic collection of cerebrospinal fluid was seen caudal to the tumor. Complete removal required transection of the adherent nerve root fascicles. Histological analyses indicate that the lesion was a lobular capillary hemangioma, which, to the authors' knowledge, appears to be one of the first recorded examples of such a case. ( info)

4/210. Eccrine angiomatous hamartoma: report of seven cases.

    Eccrine angiomatous hamartoma is a rare cutaneous lesion. Histologically it is characterized by the proliferation of eccrine glands, vascular structures and occasionally other elements in the middle and deep dermis; we now report seven further cases of this condition, two with lipomatous involvement and also discuss its nosology.

5/210. Cutaneomeningospinal angiomatosis (Cobb syndrome) with tethered cord.

    A newborn presented with a skin-covered lumbar mass with a subcutaneous hemangioma and on a magnetic resonance image (MRI) revealed a tethered spinal cord with a local mass. The mass had signal characteristics compatible with a lipoma. An initial diagnosis of a lipomeningocele with tethered cord was made, and the patient underwent surgical exploration and subtotal resection of the mass. A follow-up MRI revealed that the cord was still tethered, but an additional mass was present. The initial mass with signal characteristics of lipomatous tissue was accompanied by a low-signal mass in the lumbosacral canal, ventral to the cord, and bilateral enlargement of the foramina at the lumbosacral level. Because of a concern for an intraspinal tumor, a second operative intervention was performed. Multiple biopsies of the mass inside the spinal cord, the nerve roots and at the level of the foramina revealed angiomas that had similar pathology in all the specimens. A partial resection of the masses and a release of the tethered cord was performed by sectioning the thickened filum terminale. The diagnosis of Cobb's syndrome was made. The unique association of a tethered cord and the Cobb syndrome is reported here. ( info)

6/210. Laryngeal paraganglioma in a five-year-old child--the youngest case ever recorded.

    A paraganglioma is a neuroendocrine neoplasm that originates from the paraganglion cells of the parasympathetic system. The average age of presentation is in the fifth decade. We report a case of laryngeal paraganglioma in a five-year-old child, the youngest case ever recorded. The features of paraganglioma which differentiate it from other tumours are also discussed.

7/210. Prepartum mixed type cavernous-capillary hemangioma arising in nevus flammeus.

    OBJECTIVE: Capillary hemangioma may appear de novo and involute during the first decade of life, but rarely during pregnancy. This study describes the clinical and histologic findings of an eyelid mixed type cavernous-capillary hemangioma arising in a nevus flammeus and discusses the differential diagnosis of this lesion. STUDY DESIGN: Clinicopathologic case report. INTERVENTION: A reddish, protruding eyelid mass arising from a nevus flammeus at the eyelid margin in a 26-year-old woman was monitored during her pregnancy. Postpartum, the mass was excised and examined histologically. RESULTS: The lobulated tumor recurred during the second pregnancy and partially regressed following delivery. It was composed of mixed elements of cavernous and capillary hemangioma that superficially resembled Kaposi sarcoma, set against the background of a nevus flammeus. CONCLUSION: The differential diagnosis of discrete prepartum vascular tumor arising in nevus flammeus includes mixed capillary-cavernous hemangioma, pseudo-Kaposi sarcoma, granuloma gravidarum, and angiodermatitis. A common stimulus during pregnancy may be the inciting factor for the development of these tumors. ( info)

8/210. Diffuse neonatal hemangiomatosis with extensive involvement of the brain and cervical spinal cord.

    BACKGROUND: Diffuse neonatal hemangiomatosis (DNH) is a rare disorder first recognized at birth or during the neonatal period. DNH is characterized by numerous cutaneous and visceral hemangiomas involving three or more organ systems. MATERIALS AND methods: Although the skin and liver are most frequently affected, we present a case of DNH demonstrating an unusual predilection for the central nervous system (CNS). RESULTS AND CONCLUSION: We report the imaging findings in a patient with this disorder, paying particular attention to the features seen on cranial sonography and spinal MR imaging. ( info)

9/210. Posterior mediastinal capillary hemangioma with extradural extension resembling neuroblastoma.

    We present two patients with posterior mediastinal capillary hemangiomas that were paraspinal and had intraspinal extension. Computed tomography demonstrated the strikingly hypervascular nature of these tumors, distinguishing them from neuroblastoma. ( info)

10/210. Pulmonary capillary hemangiomatosis in an asymptomatic elderly patient.

    Thoracic hemangiomatosis is an extremely rare condition of the thorax of unknown origin: thin-walled capillary blood vessels infiltrate the lung parenchyma, blood vessels, interlobular septa, bronchiolar walls and pleura. The infiltration of pulmonary veins and venules induces secondary pulmonary veno-occlusive disease and pulmonary hypertension with a slowly progressive clinical course. This condition can be associated with vascular dementia and disseminated intravascular coagulation (DIC). ( info)
