We report on 4 cases of brain tumors associated with tuberous sclerosis. In each case the tumor was in the region of Monro's foramen and was associated with ventricular dilatation. Computer tomography scans, which were performed in 3 cases, revealed well-circumscribed high-density masses which were markedly enhanced by contrast medium. 3 patients underwent craniotomy. Total extirpation was performed in 2 patients. Both of them are doing well postoperatively. However, 1 patients whose tumor had been partially resected died of recurrence 6 years after surgery. The pathology of three tumors was different in each case: plump cell astrocytoma, hemangioma and astroblastoma.

Aqueductal stenosis is induced by widely various causes. These causes include congenital stenosis, tumor or inflammation. Among them vascular malformation is a very rare cause. In this paper we present a rare case of aqueductal stenosis caused by venous angioma. The patient was a 28-year-old female, who suffered from headache and double vision. On admission, CT and MRI showed lateral and third ventricular dilatation not but fourth ventricle, suggested aqueductal stenosis. Gd-DTPA enhanced T1-weighted MR image showed an abnormal draining vein passing through the orifice of the aqueduct. Angiography demonstrated the umbrella sign which was specific sign of the venous angioma. We performed endoscopic third ventriculostomy. Postoperative neuroradiological examination showed shrinkage of the ventricles and the symptom of the patient improved markedly. In the past literatures, five cases of aqueductal stenosis due to venous angioma have been reported. Although venous angioma is congenital, all five cases had been symptomatic at adult stage. Detailed evaluation of pre-and post-operative MRIs suggest that aqueductal stenosis induced enlargement of the lateral and third ventricles, which led narrowing of the suprachiasmatic cistern and the peri-mesencephalic cistern, and downward displacement of medulla and tonsil into the foramen magnum. As a result, hydrocephalus is aggravated gradually.

Pulmonary infantile hemangiomas are extremely rare in infancy and childhood. We describe a case of a 22-month-old infant who presented with repeated chest infections. Imaging studies revealed a solitary parenchymal lung lesion in the left upper lobe, an atrial septal defect, and mild right ventricular dilatation. Various investigations failed to delineate the precise nature of the lung lesion and it was resected. Histological examination of the lung lesion showed an infantile hemangioma, which expressed glucose transporter-1 protein, GLUT-1, a marker of infantile hemangiomas. This case represents a unique coexistence of 2 lesions, both of which resulted in right-sided overload, contributed to mainly by the atrial septal defect causing increased volume and, to a lesser extent, by the pulmonary hemangioma resulting in increased pressure. This case also emphasizes the fact that infantile hemangioma, although rare, should be considered as a differential diagnosis of solitary lung lesions.

Large facial haemangiomas have a high rate of complications and can be associated with neurological, ophthalmological and cardiac abnormalities (PHACE syndrome; Posterior fossa malformations, Haemangiomas, Arterial anomalies, Coarctation of the aorta and cardiac defects, and Eye abnormalities). However, a thorough clinical examination is absolutely necessary. In fact, even in the absence of a PHACE syndrome, large haemangiomas can induce important complications. In the present brief report we describe a case of left ventricular dilatation in a 6-month-old girl due to a giant facial haemangioma. Left ventricular dilatation has been evaluated by two-dimensional echocardiography. Studies to identify other major arteriovenous malformations were negative. Medical therapy with diuretics, angiotensin-converting enzyme (ACE) inhibitors and steroids was able to halt the progression towards left ventricular dysfunction, avoiding an early surgical approach for a disease that very often is self-limiting.
