Progressive Neurosarcoidosis Presenting as Idiopathic Hypopituitarism With Atypical Radiological Features for 13 Years.

Sarcoidosis is an immune-mediated multisystem condition of unknown etiology, characterized by non-caseating granulomatous inflammation. While it commonly affects the lungs and the reticuloendothelial system, it can affect any organ. Most of such cases involve the central nervous system, but the condition rarely presents with symptoms related to hypothalamic-pituitary dysfunction.

[Pituicitoma in a patient with neurofibromatosis type 1].

Pituicytoma is a rare low degree tumor that arises from pituicytes in the infundibulum and posterior pituitary gland. As they do not have characteristic radiological features, they can be misdiagnosed as pituitary adenoma, meningioma, or craniopharyngioma. Clinically, patients can present with hormonal disturbances, headaches and visual field defects.

Permanent pacemaker implantation for atrioventricular block secondary to acute pancreatitis in a patient affected by panhypopituitarism.

Background: Hypopituitarism may trigger the development of acute pancreatitis (AP) through multiple mechanisms. AP may alter normal intracardiac conduction leading to an atrioventricular block. Due to the lack of similar cases, the correct timing and indication for pacemaker implantation in such a setting are unknown.

Anterior Pituitary Hormones are Important in Growth, but does their Deficiency Cause Skeletal Deformity? A Case Report.

Hypopituitarism is a clinical syndrome that occurs when the anterior pituitary gland fails to secrete one or more hormones. Developmental delay is frequently seen in these patients. However, skeletal deformities and postural instability are unexceptional.

Cavitating Osmotic Demyelination Syndrome Following Correction of Chronic Hyponatremia in Sheehan's Syndrome: A Novel Case Report.

Introduction: Rapid correction of hyponatremia can result in osmotic demyelination syndrome (ODS). Sheehan's syndrome, a rare pituitary disorder caused by severe postpartum hemorrhage, is a potential cause of chronic hyponatremia. This case report describes a rare progression of extrapontine myelinolysis to central pontine myelinolysis, ultimately leading to ODS, following the correction of chronic hyponatremia associated with Sheehan's syndrome.

Case report: Pediatric hepatopulmonary syndrome despite strict weight control after craniopharyngioma surgery.

Childhood-onset craniopharyngiomas, though rare, are intracranial malformations that can cause obesity by disrupting the hypothalamus, a condition that often persists even after tumor resection. This severe obesity increases the risk of diabetes and fatty liver disease in childhood. Concurrently, panhypopituitarism, including growth hormone (GH) deficiency, may develop.

Endocrine sequelae after pediatric craniopharyngioma treatment: a single-center retrospective cohort study.

Objectives: Craniopharyngiomas (CP) are rare brain tumors with a low mortality rate, but with significant morbidity, in part due to the various long-term endocrine sequelae related to hypothalamic/pituitary deficiencies. Our objective was to assess the prevalence of endocrine dysfunction and outcome after treatment of CP at our institution and to apply the novel diagnostic criteria for hypothalamic syndrome (HS). In addition, we give an overview of treatments already attempted for hypothalamic obesity (HO).

The molecular basis of hypoprolactinaemia.

Hypoprolactinaemia is an endocrinopathy which is typically encountered as part of a combined pituitary hormone deficiency picture. The vast majority of genetic causes identified to date have been in the context of congenital hypopituitarism with multiple co-existent endocrinopathies. This is primarily with its closest hormonal relation, namely growth hormone.

Transcriptional and morphological responses following distinct muscle contraction protocols for Snell dwarf (Pit1) mice.

The Snell dwarf mouse (Pit1), an animal model of congenital combined pituitary hormone deficiency, displays skeletal muscle weakness. While enhanced responsivity to repeated exposures of muscle contractions have been documented for Snell dwarf mice, the response following single exposure to distinct contraction protocols remained uncharacterized. The purpose of this study was to investigate the muscle recovery of Snell dwarf and control littermate mice following a single exposure to two separate protocols-an intermittent slow velocity (30°/s) contraction protocol or a continuous rapid velocity (500°/s) contraction protocol.

A Diagnosis of Sheehan's Syndrome: Better Late Than Never.

A middle-aged woman presented with history of fatigue, low mood, swelling of limbs, and facial puffiness. On detailed history taking, she also complained of salt craving, secondary amenorrhea, and loss of libido for almost a decade. Investigations revealed pan-hypopituitarism.

Wrong Tissue at the Wrong Place: A Rare Case of Hypopituitarism Secondary to Metastatic Renal Cell Carcinoma.

Metastasis to the pituitary gland is a very rare occurrence. The most common primary cancer that metastasizes to the pituitary are breast cancer and lung cancer. Most of the pituitary metastases are asymptomatic.

Neurosarcoidosis With Panhypopituitarism: Two Cases and Literature Review.

Neurosarcoidosis (NS) with hypothalamic-pituitary (HP) involvement (HP-NS) is a rare clinical condition, conferring variable hormonal deficits that are typically irreversible. Here, we present 2 cases of NS with panhypopituitarism. The first patient presented with cauda equina syndrome and arginine vasopressin deficiency, while the second developed recurrent optic neuritis and vision loss in the setting of a sellar mass.

Sheehan's syndrome presenting with panhypopituitarism and central diabetes insipidus: a case report.

Background: Sheehan's syndrome is a rare condition, which is classically characterized by anterior pituitary hypofunction following postpartum shock or hemorrhage. While diabetes insipidus (DI) is not commonly associated with Sheehan's syndrome, we present a rare case of a multiparous female developing rapid-onset panhypopituitarism and DI following severe postpartum hemorrhage.

Case Presentation: A previously healthy 39-year-old woman, gravida 5, para 4, presented with hypovolemic shock after vaginal delivery, attributed to severe postpartum hemorrhage, necessitating emergent hysterectomy.
