A case of Sheehan's syndrome with delirium

Myopathic syndrome revealing a rare condition: Sheehan syndrome, a case-based review

This report presents a case of a Sheehan syndrome diagnosed with a delay of 29 years after occurrence of first symptoms, following a laborious birth ended with dead fetus and massive hemorrhage. The 50-year-old patient, with early menopause from the age of 21, is referred to our rheumatology department to investigate the etiology of a myopathic syndrome, which started 2 months before and gradually worsened. The differential diagnosis took into consideration the autoimmune, infectious, paraneoplastic, endocrinological, and drug-induced myopathic syndrome. Paraclinical investigations revealed panhypopituitarism, and cerebral magnetic resonance imaging detected empty-sella. The etiology of a myopathic syndrome is often multifactorial; therefore, it is important to continue the investigations even after identifying one possible etiological factor, especially when it does not seem to fully explain the clinical-paraclinical picture. Usually, the multiple dimensions of panhypopituitarism bring the patient to various medical specialties depending on the dominant symptomatology. Given the rarity of the above-mentioned syndrome in the present, and the long gap between the initial event and the final diagnosis, its identification continues to be a challenge.

Sheehan Syndrome Presenting with Psychotic Manifestations Mimicking Schizophrenia in a Young Female: A Case Report and Review of the Literature

Introduction

Sheehan syndrome presents with features of multiple hormone deficiencies including lactation failure and amenorrhoea as well as with features of central hypothyroidism and adrenocorticotropic hormone deficiency. Psychiatric manifestations are mostly limited to cognitive impairment. Psychotic presentations are rare and limited to case reports. Case Presentation. A 32-year-old female was evaluated for fearfulness and delusions for one year. She had persecutory and bizarre delusions, delusion of thought possession, and elementary auditory hallucinations. These began four months after the birth of her third child. The delivery had been complicated with postpartum haemorrhage. Her symptoms caused the functional decline and progressively worsened, resulting in suicidal ideation. Cognitive assessment revealed mild impairment in attention. Further inquiry revealed lethargy, constipation, cold intolerance, and lactation failure. She was slow, having dry skin, puffy face, and bradycardia with a blood pressure of 80/60 mmHg (supine) and 70/50 mmHg (standing). She had hyponatraemia, elevated creatine phosphokinase, low thyroxine, prolactin, FSH, LH, and IGF-1. She had poor cortisol and growth hormone response to the insulin tolerance test. MRI-pituitary showed empty sella. A diagnosis of Sheehan syndrome was made. Her symptoms improved completely after the initiation of levothyroxine and hydrocortisone.

Conclusions

Sheehan syndrome can present with psychotic symptoms mimicking schizophrenia with variable involvement of cognition. Detailed reporting of these patients would enhance better characterization of the clinical presentation and risk profile of these patients.

Psychosis associated with hypopituitarism

Psychosis is one of many possible psychiatric disturbances associated with endocrinologic abnormalities. Previous reports linking psychosis with hypopituitarism have been limited. Furthermore, such reports suggested that the psychotic symptoms were more accurately part of a delirium. We report two patients with hypopituitarism who presented with psychotic symptoms, in the absence of an altered sensorium. They were assigned functional psychiatric diagnoses on initial presentation. Their symptoms abated after correction of underlying hormonal abnormalities. The evaluation and treatment of psychiatric disturbances associated with hypopituitarism are discussed.
