Colloid cysts are relatively rare benign intracranial lesions preferentially located within the third ventricle. There are only a few reports in which they have been found to be ectopic, such as in the fourth ventricle. A young female presented on with spontaneous non-traumatic cerebrospinal fluid (CSF) rhinorrhoea for three months which was positional in nature, relieved temporarily by neck fl...

Colloid cysts are benign intracranial tumours usually occurring in the front part of the third ventricle. Clinical presentation may be non-specific and heterogeneous. The problems are frequently associated with development of hydrocephalus, these cysts may cause. We describe three cases of patients with diverse clinical symptoms, who underwent surgery for colloid cysts of the third ventricle. I...

The incidence of papillary carcinoma arising in a thyroglossal duct cyst is rare and occurs less than 1% of thyroglossal cysts. We report a case of cystic swelling in the mid-line neck in a young female patient. Fine needle aspiration of the cyst revealed colloid material and macrophages CT scan showed a cystic lesion with calcification. Histopathological examination of the cyst showed papillar...

We report the nonoperative treatment of a recurrent, multilevel spinal aneurysmal bone cyst by injection of 32P chromic phosphate colloid into the cyst. The patient was then followed up with serial CT examinations, which showed stabilization and progressive ossification within the lesion. The rationale, alternatives, and possible contraindications to radionuclide ablation of spinal aneurysmal b...

Colloid cysts comprise 0.5 to 1% of intracranial tumors that are most commonly diagnosed in third to fifth decade of life.1,2 These benign tumors are generally seen in the anterosuperior portion of the third ventricle and are by far the most common of the intraventricular masses here.3,4 Colloid cysts are of endodermal (foregut) origin and are lined by pseudostratified, cuboidal, or columnar ep...
