Open rhinoplasty for treatment of nasal tip haemangioma

Haemangiomas are the most common tumours of infancy. They typically proliferate then involute with considerable variation as regards to their rates of proliferation and involution. Haemangioma of the nasal tip is a lesion of special characteristics. During proliferation, it expands, contracts and deviates the nasal cartilages. Particularly, it regresses slowly and frequently involutes incompletely. That is why excision of the lesion is frequently suggested. The present study was conducted to evaluate open rhinoplasty after initial non-excision treatment modalities namely, intra-lesional corticosteroid injections and laser treatment, as a protocol of treatment for nasal tip haemangiomas. Twelve patients with nasal tip haemangiomas were included in the present study. Patients of both sexes, of different ages, with deep and mixed haemangiomas were studied. Disfigurement was the constant presenting symptom. Initial non-excision treatment reported different responses as denoted by the regression of the lesions’ size. Haemangiomas constantly extended between the medial crura of the alar cartilages as noted by the constant widening of the columella pre-operatively and the obvious separation of the nasal cartilages intra-operatively. This separation was constantly found to require approximation by sutures. The results of the present study concluded that whenever an early presentation with nasal tip haemangioma could be established, initial non-excision treatment followed by open rhinoplasty could be a useful protocol of treatment. Within the limitations of the present study, this protocol could achieve an early, safe and effective treatment for nasal tip haemangiomas with provisionally acceptable cosmetic outcomes so far.     

An unusual neck lump: intramuscular haemangioma of the sternocleidomastoid muscle

Neck lumps can often present a diagnostic dilemma, with a wide pre-operative differential diagnosis. We present an unusual case of an intramuscular haemangioma arising in the sternocleidomastoid muscle. Pre operative diagnosis is often difficult, as these lesions are extremely rare in the head and neck region and only few sporadic cases have been reported in the literature. We report the presentation diagnosis and management of intramuscular haemangiomas of the sternocleidomastoid muscle.

Haemangioma or vascular malformation of the tympanic membrane? a case report and review of literature

Benign vascular lesions are rarely found on the tympanic membrane. We report a case of such a lesion in a novel location, with review of the relevant literature. We also highlight the significance of accurate classification of such lesions, proposing adoption of more pathophysiologically-correct nomenclature of “haemangioma” and “vascular malformation”.     

Resorption time and tissue reactions with magnesium rods in rats and rabbits

Summary Studies in rats and rabbits show that pure (99.8+%) magnesium wires with a diameter of 0.25 and 0.50 mm, which are implanted subcutaneously and intramuscularly, will be totally resorbed within 20 weeks but will be dissolved completely within 10 weeks if they are treated with 10% acetic acid before implantation. According to morphologic and electromyographic studies magnesium rods cause only a very mild foreign body reaction in normal tissue and do not harm the function or structure of neighbouring nerves and muscle fibres. This suggests that a refill of haemangioma with magnesium seeds is advisable at intervals of 8 weeks and allows the conclusion that magnesium implants can safely be used also in close proximity to facial nerve branches and delicate muscle fibres.     

Pancreatic haemangioma in infancy: the place of radiology

Pancreatic haemangiomas in infants are rare. Seven cases have been reported in the literature to date. We report two new cases. One of our cases had antenatal diagnosis and was associated with atypical portal vein thrombosis. The diagnosis was obtained by percutaneous biopsy without complication. For both cases, regression was observed without treatment.     

Classification and imaging of vascular malformations in children

Accurate diagnosis and classification of haemangiomas and vascular malformations is essential for prediction of outcome and rational therapeutic intervention. The purpose of this review is to demonstrate how radiological techniques, including projectional radiography, ultrasound and colour flow imaging, magnetic resonance imaging, and conventional venography and arteriography can aid in the diagnosis and classification of vascular malformations in children, and to guide the radiologist in the use of modern nomenclature.     

MRI of unusual lesions in the internal auditory canal

We report the MRI findings of six unusual lesions of the internal auditory canal: three haemangiomas, one lipoma, one metastasis and one traumatic neuroma. We compare the findings to those of 20 intracanalicular schwannomas. We noted the site and size of the tumour, its signal intensity, borders and the homogeneity of enhancement were studied on T1-weighted images before and after intravenous contrast medium and T2-weighted images. Most schwannomas were homogeneous lesions, isointense on T1- and T2-weighted images, and strongly enhancing. Spontaneous high signal on T1-weighted images, heterogeneous contrast enhancement and extranodular enhancement were helpful for recognising lesions other then schwannomas; site, size and signal on T2-weighted images were not. All the haemangiomas had a specific pattern of contrast enhancement, with an anterior core intensely enhancing portion and a posterior portion which enhanced moderately or not at all.
