OBJECTIVE: Does dynamic gadolinium-enhanced imaging with simultaneous acquisition of coronal and sagittal planes improve diagnostic accuracy of pituitary microadenomas compared with coronal images alone? METHODS: Fifty-six patients underwent 3-T sella MRI including dynamic simultaneous acquisition of coronal and sagittal planes after gadolinium injection. According to conspicuity, lesions were divided into four scores (0, no; 1, possible; 2, probable; 3, definite delayed enhancing lesion)...

BACKGROUND: Magnetic resonance imaging (MRI), an advancement which followed computed tomography (CT) is expensive and inaccessible in most developing countries. However it is the procedure of choice in evaluating sellar and parasellar lesions. Its major advantages are its superior soft tissue contrast differentiation, its capacity for multiplanar imaging and nonexistence of ionising radiation. Its use is relatively new in Nigeria, a developing economy in Africa. Since its introduction in 2005, it has been utilised extensively for neuroimaging at the University College Hospital (UCH), Ibadan; a large hospital in south-western Nigeria...

Choroid plexus papillomas are rare tumors of the central nervous system and are usually confined to the ventricular system. We illustrated a primary choroid plexus papilloma in the pituitary fossa. A 31-year-old female presented with amenorrhea and intermittent galactorrhoea, with no visual complaints in the last 2 years. Endocrine testing showed no hormone excess or deficiency of the pituitary and target glands, except for a higher prolactin level (56 ng/ml). A sharply circumscribed regular mass in the sellar region occupying the entire sella turcica and extending into the suprasellar cistern was demonstrated on MR imaging with gadolinium diethylenetriamine pentaacetic acid...

We report on one case of variant origin of right ophthalmic artery (OA) from C4 choroidal segment of the right supraclinoid internal carotid artery. A 41-year-old woman affected by bitemporal hemianopsia performed Magnetic Resonance Imaging with gadolinium showing tuberculum sellae meningioma. During angiography we observed this variant of origin of OA. At surgical dissection, we observed this variant in carotid cistern.

OBJECTIVE: The purpose of this study was to determine whether the preoperative MRI findings of enhanced diffusivity, macrocyst content, and internal hemorrhage in pituitary macroadenomas are predictive of successful transsphenoidal hypophysectomy. MATERIALS AND METHODS: We retrospectively reviewed the preoperative and postoperative sella protocol MR images of 28 patients who underwent transsphenoidal hypophysectomy for chiasm-compressing macroadenoma. Chiasmatic decompression defined surgical success...

We report the case of a 21-year-old pregnant women (36 WA) presenting intensive headaches and visual disturbances. Those sellar compression symptoms have made us suppose the diagnosis of autoimmune hypophysitis. MRI has confirmed the typical aspect of symmetric enlargement of the pituitary gland with a strong and homogenous enhancement after gadolinium. This pathology associated to a high morbidity and mortality due to partial or complete deficit of the anterior pituitary hormones, shall be reminded more often...

INTRODUCTION: To clarify whether a three-dimensional-gradient echo (3D-GRE) or spin echo (SE) sequence is more useful for evaluating sellar lesions on contrast-enhanced T1-weighted MR imaging at 3.0Tesla (T). METHODS: We retrospectively assessed contrast-enhanced T1-weighted images using 3D-GRE and SE sequences at 3.0T obtained from 33 consecutive patients with clinically suspected sellar lesions. Two experienced neuroradiologists evaluated the images qualitatively in terms of the following criteria: boundary edge of the cavernous sinus and pituitary gland, border of sellar lesions, delineation of the optic nerve and cranial nerves within the cavernous sinus, susceptibility and flow artifacts, and overall image quality...

BACKGROUND: Magnetic resonance imaging of the breast has emerged as a valuable imaging tool in addition to conventional imaging modalities. It has high sensitivity for malignant lesions and can detect mammographically, sonographically and clinically occult cancers. "MR only" lesions are best biopsied under MR guidance; however, this may be a challenging task. OBJECTIVES: To evaluate our initial clinical experience with MR-guided core needle breast biopsy and MR-guided needle localization...

A 49-year-old woman presented with headache, vomiting and visual disturbance. Neurological examination revealed bitemporal hemianopsia with poor visual acuity. Magnetic resonance imaging showed a bulky intra-suprasellar mass, which was isointense with brain parenchyma on T1-weighted images, and slightly hyperintense on T2-weighted images. After gadolinium administration, the mass was homogeneously enhanced. The mass was partially removed by the endonasal transsphenoidal approach and then the remnant mass was totally removed by the transcranial approach five months later...

A 26-year-old man presented with a xanthogranuloma located exclusively in the suprasellar region manifesting as general fatigue, bitemporal hemianopsia, and polyuria. Endocrinological examination disclosed severe hypopituitarism. Magnetic resonance imaging demonstrated a clearly defined suprasellar mass that was heterogeneously enhanced after gadolinium administration and was markedly hypointense on T(2)-weighted images. The tumor was subtotally removed under a preoperative diagnosis of craniopharyngioma. Histological examination found fibrous tissue with abundant cholesterol clefts, multinucleated giant cells, and hemosiderin deposits, but no epithelial cells...

Pituitary abscess (PA) is an infrequent disease, which consists of an infection within the sella turcica that might be life-threatening. We present here two cases of this rare entity. Case 1: A 53-year-old woman was followed for an incidentally found pituitary cyst. Six years later the cyst enlarged and transsphenoidal surgery was performed. Two years later, the patient developed sudden onset of intense headache and nausea. The MRI showed a 2 by 2.5 cm sellar and suprasellar mass, that enhanced peripherally with gadolinium contrast and became hyperintense in T2-weighted images, suggesting a new-onset cystic lesion...

We describe a rare case of HCV-related recurrent multiple hepatocellular carcinoma (HCC) metastasizing to the skull base involving multiple cranial nerves in a 50-year-old woman. The patient presented with symptoms of ptosis, fixation of the right eyeball, and left abducens palsy, indicating disturbances of the right oculomotor and trochlear nerves and bilateral abducens nerves. Brain contrast-enhanced computed tomography (CT) revealed an ill-defined mass with abnormal enhancement around the sella turcica. Brain magnetic resonance imaging (MRI) disclosed that the mass involved the clivus, cavernous sinus, and petrous apex...

Hypopituitarism can be caused by tumor, inflammation, granuloma and injuries. Once pituitary function is disturbed, hormone replacement therapy is necessary for the remaining life span in most cases. We have experienced a rare case of a unique intrasellar mass associated with pituitary dysfunction in which both spontaneously reversed. A 61-yr-old woman developed hypoadrenalism and central diabetes insipidus (cDI). Magnetic resonance (MR) imaging revealed a lobular, strong hypointense lesion with spotty signal in the middle of the hypophysis...

Prostatic carcinoma accounts for only 3.6% of orbital metastases encountered in clinical practice. We report the clinical presentation and response to treatment of a patient with metastatic prostatic carcinoma to the sella turcica. A 73-year-old man presented with a three-months history of progressive right proptosis associated with increasing diplopia in down-gaze and slightly decreased visual acuity. Gadolinium-MRI scans of the head revealed a left osteoblastic intrasellar mass, displacing the pituitary gland...

The aim of this study was the evaluation of the normal sellar anatomy in vitro and in vivo with high-field MRI and its application in the diagnosis of sellar pathologies in comparison to standard MRI. All high-field MR images were obtained using a 3T Bruker Medspec 30/80 Scanner with a head birdcage transmit/receive coil and an actively shielded gradient system with a maximum gradient strength of 45 mT/m. Firstly an in vitro study of the sella turcica was performed to depict normal pituitary and sellar anatomy at high field...
