Diagnosis of cavernous haemangiomas by computed tomography and angiography

Computed tomography and angiographical findings of cavernous haemangiomas of the brain are reported on the basis of six cases of the authors, and a review of the literature. Computed tomography showed well demarcated, round densities with tiny calcifications, and mild contrast enhancement (0-25 HU), with no mass effect and with open sulci round the lesion. The angiographical findings were normal except in one patient with an early draining vein and in another with a late draining vein; consequently an injection of at least 10 to 15 ml of contrast medium, and a prolonged angiographical series are recommended. According to the literature, capillary blush may also be seen in angiography. If both CT and angiography are used the diagnosis is definitive, and a neoplasm can be excluded. In five of our patients the diagnosis was verified surgically and histologically, while the sixth patient was not operated on because the frontoparietal lesion was near the motor region. In most cases, surgical removal is easy and successful.

“…Tiny branches from the cavernous segment of the internal carotid artery may be revealed on digital subtraction angiography which are otherwise not appreciable on routine anatomical imaging[ 7 , 8 ]. Hypertrophied pial arteries, tumor stain and large draining veins were described in the intra-axial cavernous hemangioma closely resembling a highly vascular neoplasm[ 10 , 11 ].…”

“…None of the cases in our series showed this finding. At least two thirds of cavernous hemangiomas exhibit some degree of vascular blush unlike the parenchymal cavernous angiomas which are occult to catheter angiography[ 8 , 10 , 12 ]. Microscopically CSH consists of multiple vascular channels lined by a single layer of endothelium without muscular layer.…”

AIMTo elucidate the clinical, magnetic resonance imaging (MRI), pathological features of these lesions and asses the incremental value of diffusion-weighted imaging (DWI) in diagnosing them.METHODSFifteen consecutive patients (11 females and 4 males; mean age 40.93 years; age range 13-63 years) with cavernous sinus hemangiomas (CSH) who underwent examination between November 2008 and May 2016 were included for the analysis. MRI, clinical and surgical findings of each patient was retrospectively reviewed. DWI were also analysed and mean-apparent diffusion coefficient (ADC) value was calculated. Eleven patients underwent surgical removal of the lesion and 2 patients had biopsy only. Diagnosis of CSH was confirmed histologically in 13 patients.RESULTSEleven patients (73%) presented with headaches and 10 (66%) had cranial nerve involvement. Extra cavernous sinus extension was noted in 14 (94%). Surgery was performed in 13 (87%) and post-operative radiation was given to 4 (28%) patients. Thirteen patients remained asymptomatic on follow up. Three conspicuous imaging features were highly suggestive of the diagnosis: Lack of diffusion restriction (100%), homogeneous hyperintensity on T2 weighted image sequences (93.3%) and intense post-contrast enhancement (100%). The mean ADC was 1.82 × 10-3 ± 0.2186 cm2/s.CONCLUSIONT1-weighted hypointensity with homogeneous hyperintensity on T2-weighted sequences, intense enhancement and absence of hemosiderin within the lesion on GRE sequence favour the diagnosis. Facilitated diffusion on DWI differentiates CSH from other solid cavernous sinus lesions and significantly improves the diagnostic accuracy, a critical factor for planning surgery.

“…Presentation of scientific papers at regional and national conferences and publications in peer-reviewed journals, both local and overseas, served to enhance this reputation. [12][13][14][15] It was the appropriate time to start a postdoctoral training course in neuroradiology for general radiologists wishing to widen their knowledge and skills. In those days, neuroradiology formed a negligible part of radiology training curriculum in most medical colleges in India.…”

This is the second part of the two-part paper on the history of development of neuroradiology at the Sree Chitra Tirunal Institute of Medical Sciences and Technology, Thiruvananthapuram. In this part, the authors describe the evolution of interventional procedures at their institute from the initial techniques of free-flow embolization as a palliative procedure for large arteriovenous malformations (AVMs) to the more refined techniques of selective embolization using microcatheters, calibrated leak balloons and liquid polymerizing embolic agents. The authors acknowledge the immense encouragement and support provided to them by the French neurointervention pioneers Prof. Luc Picard and Prof. Jacques Moret in this endeavor.
