INTRODUCTION: Persistent craniopharyngeal canal (PCC) is a rare anomaly of the base of the skull. PCC is defined as a well-corticated osseous canal, extending from the roof of the nasopharynx to the base of the sella over the course of the sphenoid corpus. We reported a PCC case with unique associations. The magnetic resonance imaging findings are discussed. CASE PRESENTATION: We report a case of a 2-year-old boy with persistent craniopharyngeal canal, bilateral microphtalmia with large colobomatous cyst, and ectopic adenohypophysis with Rathke cleft cyst...

Abscess inside the pituitary fossa is very rare. Such abscess can be primary, occurring in an otherwise healthy pituitary gland, or secondary, developing inside a diseased gland (ie, harbouring craniopharyngioma, Rathke's cleft cyst, etc). Secondary pituitary abscess inside a craniopharyngioma remains an extremely rare occurrence. Our literature search revealed only six such cases reported so far. In this report, we present the seventh case of craniopharyngioma with abscess in a 38-year-old woman. We describe the uniqueness of the clinical presentation of our case, the radiological pointers to the possible diagnosis and the management issues in our patient...

Background: Despite the broad category of differentials for sellar region, most of them present with similar clinical signs and symptoms. Headache and visual disturbance are among the frequently seen as presenting symptom. Visual field (VF) assessment is one of the crucial component of neuroophtalmologic assessment and mean deviation (MD) value from automated perimetry allows quantification of the visual field defect. We formulated a study to look into the factors that affect the visual field outcome after surgery...

BACKGROUND: Xanthogranulomas are inflammatory masses most commonly found at peripheral sites such as the skin. Sellar and parasellar xanthogranulomas are rare and present a diagnostic challenge as they are difficult to differentiate from other sellar lesions such as craniopharyngiomas and Rathke's cleft cysts pre-operatively. Their radiological imaging features are yet to be clearly defined, and clinical outcomes after surgery are also uncertain. This study reviews clinical presentation, radiological appearances, and clinical outcomes in a cohort of patients with pituitary xanthogranulomas...

INTRODUCTION: Rathke's cleft cysts (RCC) are benign lesions of the sella that often present with headache. It is not currently well-established whether surgical resection of RCC results in resolution of headache. We conducted a meta-analysis to examine the effect of RCC resection on headache resolution. METHODS: PubMed, EMBASE, and Cochrane databases were searched through June 2017 for articles that evaluated the effect of RCC resection on headache resolution. Pooled effect estimates were calculated using fixed- and random-effects models...

BACKGROUND: IgG4-related hypophysitis is a rare clinical entity that forms part of an emerging group of multi-organ IgG4-related fibrosclerotic systemic diseases. The rare prevalence of the disease, presenting features that overlap with other sellar pathologies, and variable imaging features can make preoperative identification challenging. PURPOSE AND METHODS: We report three cases of isolated IgG4-related hypophysitis with atypical clinical and imaging features that mimicked those of pituitary apoplexy and other sellar lesions...

The increasing recognition of pituitary disorders and their impact on quality of life and longevity has made understanding of this small gland a subject of paramount importance. Pituitary pathology has seen many significant studies that indicate progress in identification and classification of pituitary lesions, as well as improved management strategies for patients. In this review, we outline six major areas of advances: (i) changes in terminology from 'adenoma' to 'pituitary neuroendocrine tumour'; (ii) reclassification of hormone-negative tumours based on transcription factor expression that defines lineage; (iii) updates in new pathogenetic mechanisms, including those that underlie rare lesions such as X-LAG and pituitary blastoma; (iv) clarification of hypophysitis due to immunotherapy, xanthomatous hypophysitis due to rupture of a Rathke's cleft cyst and IgG4 disease as the cause of inflammatory pseudotumour; (v) the consolidation of pituicytoma variants, including spindle cell oncocytoma and granular cell tumour based on thyroid transcription factor-1 (TTF-1) reactivity; and (vi) the pathogenetic mechanisms that distinguish papillary from adamantinomatous craniopharyngioma...

BACKGROUND: Diabetes insipidus (DI) is a major complication of transsphenoidal surgery (TSS). DI usually occurs within a couple of days after TSS. Delayed occurrence of postoperative DI is rarely observed and its developing mechanisms remain unknown. METHODS: Six patients were identified as having postoperative delayed DI, which was defined as DI that first occurred 2 or more weeks after TSS. They consisted of 1 male and 5 females, and their mean age was 38.3 years (range, 10-76 years)...

Background: To determine the clinical significance of thickening of the sphenoid sinus mucosa (TSSM) in Rathke's cleft cyst (RCC). Methods: We retrospectively reviewed patients with pituitary lesions. A total of 99 patients, who underwent surgery of pituitary lesions between 2008 and 2015, were analyzed to evaluate the clinical significance of TSSM using magnetic resonance imaging. The patients with TSSM were evaluated for their characteristics. Results: Of the 99 operations, 15 patients with paranasal sinusitis, direct invasion to the sellar floor, and/or a history of transsphenoidal surgery were excluded...

A 17-year-old girl presented with polyuria (7 L/day) and polydipsia for one year. Initial urine osmolality was 113mOsm/kg H2O. Following 6 h of fluid restriction, serum plasma osmolality reached 300mOsm/kg H2O, whereas urine osmolality was 108mOsm/kg H2O. Urine osmolality was increased by 427% from 108 to 557mOsm/kg after vasopressin challenge. The patient was diagnosed with central diabetes insipidus, possibly derived from the atypical occupation of a Rathke's cleft cyst at the pituitary stalk following magnetic resonance imaging with enhancement...

PURPOSE: Rathke's cleft cyst (RCC) is an asymptomatic benign lesion. With increased interest in pediatric endocrinology, the prevalence of RCCs in children is also increasing. However, the clinical relevance and proper management of RCC is not well defined in children. Therefore, we investigated the clinical manifestations and radiologic features of RCC in children and adolescents, as well as the natural progression of RCC. METHODS: We retrospectively reviewed the medical records of 91 children and adolescents with RCC diagnosed with magnetic resonance imaging (MRI) in Severance Children's Hospital from January 2006 to December 2015...

BACKGROUND: The ability to preoperatively predict postoperative complication risks is valuable for individual counseling and (post)operative planning, e.g. to select low-risk patients eligible for short stay surgery or those with higher risks requiring special attention. These risks however, are not well established in pituitary surgery. METHODS: We conducted a systematic review of associations between preoperative characteristics and postoperative complications of endoscopic transsphenoidal surgery according to the PRISMA guidelines...

Rathke's cleft cyst is a cystic disease that occurs in the sella turcica or, occasionally, in the suprasellar area. An ectopic Rathke's cleft cyst is extremely rare, and its nature is less well understood. The authors report the case of a 14-year-old girl who presented with a growing cystic lesion in the prepontine cistern, immediately behind the dorsum sellae. Preoperative imaging and intraoperative investigation showed part of the cyst wall continuing into the dorsum sellae, to the pituitary gland. The cisternal portion of the cyst wall was totally resected via a right subtemporal approach...

BACKGROUND: Chiasmapexy is used to treat empty sella syndrome, and various materials are used for the elevation of the optic chiasm. However, the use of artificial substances may have the risk of graft infection, and fat and muscle may be absorbed over the long term after surgery. In addition, bone and cartilage may be unavailable in adequate amounts. Here, we describe a new technique for chiasmapexy using an iliac crest bone graft. CASE DESCRIPTION: The first patient was a 71-year-old woman who had undergone transsphenoidal surgery twice for the treatment of pituitary adenoma and Rathke cleft cyst...

Craniopharyngioma consists of adamantinomatous and papillary subtypes. Recent genetic analysis has demonstrated that the two subtypes are different, not only in clinicopathological features, but also in molecular oncogenesis. Papillary craniopharyngioma (pCP) is characterized by a BRAF mutation, the V600E (Val 600 Glu) mutation. Adamantinomatous craniopharyngioma (aCP) can be distinguished by frequent β-catenin gene (CTNNB1) mutations. Although these genetic alterations can be a diagnostic molecular marker, the precise frequency of these mutations in clinical specimens remains unknown...
