Synovial cysts are commonly found in the knee joint. Hip Joint is an infrequent site for formation of synovial cysts. The features of a large, synovial cyst on magnetic resonance imaging, occurring in the hip joint, are described.

Posterior pituitary ectopia refers to an absent normal posterior pituitary bright spot within the sella with ectopic bright signal at another site (such as the median eminence) on a weighted magnetic resonance. We describe two children with idiopathic anterior hypopituitarism who showed an ectopic posterior pituitary and absent pituitary stalk on imaging. We emphasize the association of the absent pituitary stalk in ectopic pituitary gland and low growth hormone levels.

Rupture of intracranial dermoids tumour is rare and carries with it the risk of significant morbidity as well as fatality. Three cases that presented with varying symptoms ranging from headache to chiasmatic compression and suspected to have rupture of dermoid tumour are described. The importance of MR imaging in their diagnosis is discussed.

Nasal gliomas are uncommon lesions, with approximately 100 cases reported in the literature. We present a case of intranasal glioma with a pedicle of glial tissue and defect in the cribriform plate of the ethmoid bone. Presence of such a pedicle is almost always present in the encephaloceles and is known to be distinctively uncommon in nasal gliomas.

Recognition of postoperatively retained foreign body referred euphemistically as gossypiboma is essential but is very often considerably delayed. Legal implications as well as confusing configuration patterns cause considerable dilemma in the accurate diagnosis. We present computed tomographic features of gossypiboma in two patients who presented with symptoms of fever and pain in the immediate post-operative period. A prospective radiological diagnosis is essential for further management in these patients.
