We report a rare case of capillary hemangioma of the liver in an adult. The patient was a 55-year-old man, admitted for investigation of a hepatic tumor. The tumor was seen as a hypoechoic mass with a peripheral hypoechoic ring on ultrasonography. Computed tomography (CT) showed an enhancement pattern different ...

A 13 year old girl presented with recurrent painful "varicosities" on her right calf. These lesions were subsequently clinically diagnosed as "cavernous haemangiomas" after normal duplex scanning and were excised. Histological examination revealed multiple glomangiomas (glomus tumours). A literature review revealed only two reported cases of nodular multiple glomangioma, so ...

Recently, there have been several case reports of cavernous angiomas appearing after radiation to the brain, typically in children. The time interval between irradiation and the detection of the cavernous angioma varied from three to nine years and the doses from 24 to 60 grays. We report the appearance of ...

Cavernous angiomas (cavernomas) of the cavernous sinus are uncommon, with only scattered reports in literature. Unlike their parenchymatous counterparts, they are intensely enhancing para-sellar masses, iso/hypointense in T1- and hyperintense in T2-weighted images. Differential diagnosis with para-sellar meningiomas and schwannomas can be difficult. We report three cases of this condition, ...

There are no cases in the literature describing the use of electroconvulsive therapy (ECT) in a patient with an intraorbital vascular mass. We report the clinical course of a 69-year-old female with a cavernous hemangioma of the left orbit who was successfully treated with ECT for major depressive disorder. There ...

BACKGROUND: Cavernous haemangiomas (cavernomas) are benign vascular malformations which can be found at any region within the central nervous system. Epilepsy is the most frequent manifestation of this malformation. Magnetic resonance imaging (MRI) used for the diagnostic evaluation of symptomatic seizures is a sensitive and specific method for the detection ...

Extraaxial cavernous hemangiomas are rare intracranial lesions that can be located in different cranial compartments. Extension across different tissue planes such as the subcutaneous tissue, skull, orbital cavity, intracranial dura mater, and extracranial trigeminal divisions within the same patient has not been previously reported. This 32-year-old woman suffered left exophthalmos, ...

The better understanding of the natural history of the cavernous malformations and the improvement of diagnostic methods and of microsurgical techniques have made the management of cavernous malformations possible through the conservative treatment, radiosurgery, and microsurgical resection. We present 33 cases operated at our service at Santa Casa Hospital, Belo ...

Intraosseous vascular anomalies are rare, and although they have been described in the facial skeleton, those occurring in the zygomatic bone are extremely rare. We report the case of a 38-year-old woman who presented with a painless hard swelling in the left zygomatic prominence, which was diagnosed as a cavernous ...

Klippel-Trenaunay syndrome (KTS) is a congenital malformation usually presenting limb asymmetry, abnormal development of the deep and superficial veins, and cutaneous capillary malformations. We describe the case of a 56-year-old male KTS patient who suffered from recurrent but life non-threatening lower gastrointestinal bleeding. Colonoscopy revealed multiple extensive cavernous hemangiomas in ...

OBJECTIVE: To identify clinical factors contributing to the lateralization of mesiotemporal memory functions in epilepsy by using memory-activated fMRI. METHODS: Sixty patients aged 16 to 63 years with mesial temporal lobe epilepsy (MTLE) and 20 patients aged 16 to 60 years with extratemporal epilepsy (ETE) due to circumscribed epileptogenic lesions ...

STUDY DESIGN: A case of juxtaposition of a purely extradural cavernous hemangioma and an intradural schwannoma in the thoracic spine is reported. OBJECTIVES: The objectives of this study were to present a rare and before-surgery unexpected combination of spinal tumors, which may complicate surgical removal; and to discuss the radiologic ...

Cerebral cavernous malformations (CCMs) are hamartomatous vascular malformations characterized by abnormally enlarged capillary cavities without intervening brain parenchyma. They cause seizures and cerebral hemorrhages, which can result in focal neurological deficits. Three CCM loci have been mapped, and loss-of-function mutations were identified in the KRIT1 (CCM1) and MGC4607 (CCM2) genes. ...

AIM: To evaluate the value of multi-phasic CT arterial portography (CTAP) and CT hepatic arteriography (CTHA) in differential diagnosis of liver diseases, and to improve the specificity of CTAP and CTHA for liver cancer detection. METHODS: From January 1999 to December 2002, multi-phasic CTAP and CTHA were performed in 20 ...

A case of asymptomatic right atrial cavernous hemangioma in a 50-year-old man is reported. With right atriotomy under total cardiopulmonary bypass, the right atrial mass was identified as arising from the noncoronary Sinus of Valsalva. The mass was successfully resected with the Sinus of Valsalva closed primarily. The patient is ...

INTRODUCTION: Cavernous haemangiomas (cavernomas)(CH) are relatively rare (2% of cranial tumoral pathology) vascular malformations mostly observed in the central nervous system. Their most common topographical site in brain stem is midline in the pons, for which clinical course may mimic symptoms of peripheral origin (sudden deafness, fluctuating hearing loss, Meniere-like ...

BACKGROUND AND PURPOSE: Mapping of eloquent cortex using blood-oxygen-level-dependent (BOLD) contrast functional MRI (fMRI) has rapidly gained acceptance as part of the evaluation of patients being considered for neurosurgical interventions. The BOLD signal measures local susceptibility in the blood, which can change during periods of increased neuronal activation as a ...

Cavernous hemangioma of the calvaria is a very rare disease, and patients usually present with headaches or a visible skull deformity. Few reports of patients presenting with intradiploic or epidural hemorrhages are found in the literature. No case of an intradural hemorrhage from a cavernous hemangioma of the skull has ...

Iris hemangioma is a rare intraocular tumor which can present with spontaneous hyphema. Juvenile xanthogranuloma, malignant melanoma with proliferation of vessels or hemorrhages in the region of cystic degeneration, and inflammatory granulomas are frequently confused with the true hemangiomas. Some authors have even questioned the very existence of iris hemangioma. ...

OBJECT: The aim of this study was to propose criteria to determine whether complete resection of cavernous malformations in the brainstem had been achieved. METHODS: The authors retrospectively analyzed data in 10 patients harboring a single cavernous malformation who had presented with hemorrhagic symptoms and had been followed up for ...

A 47-year-old woman presented with multiple bluish subcutaneous nodules on the trunk and upper extremities. The histological diagnosis of a subcutaneous nodule was cavernous hemangioma. Multiple cavernous hemangiomas were also found in her cerebrum, cerebellum, and medulla oblongata on magnetic resonance imaging examination. We did not detect any mutations in ...

OBJECTIVE: The integration of functional magnetic resonance imaging (fMRI) data into neuronavigation is a new concept for surgery adjacent to the motor cortex. However, the clinical value remains to be defined. In this study, we investigated the correlation between the lesion-to-fMRI activation distance and the occurrence of a new postoperative ...

We encountered a 72-year-old woman with a left atrial hemangioma arising in the appendage and growing like an extracardiac mass. Life-threatening cardiac tamponade, recurrent over a 5-year clinical course, was the only sign of this rare tumor. The extraatrial growth pattern of the tumor made it difficult to distinguish the ...

PURPOSE: Over the last decade, MRI has become the standard procedure for the diagnosis of orbital masses. Purpose of the study was to evaluate criteria for differential diagnosis for intraconal masses on MRI in a large patient group. MATERIAL AND METHODS: In a retrospective study, MR examinations of 78 patients ...

Capillary hemangiomas have rarely been reported to develop in the brain or spinal cord. Here we report the histological and immunohistochemical features of ten cases of central nervous system capillary hemangiomas (CNSCH) and compare these to those of lobular capillary hemangioma (LCH) of the skin. CNSCH showed a lobular architecture ...
