Background. Hypothyroidism is a prevalent endocrine disorder, often presenting with a spectrum of symptoms reflecting a hypothyroid state. It is also generally linked to causing mood swings, psychomotor slowing, and fatigue; however, in rare instances, it may lead to or induce acute psychosis, a condition referred to as myxedema psychosis (MP). We report a case of myxedema psychosis and present a literature review discussing its presentation, diagnosis, management, and prognosis. Case Presentation. A 36-year-old lady presented with one-week history of persecutory and paranoid delusions, along with visual and auditory hallucinations. She had no prior history of psychiatric illnesses. She underwent total thyroidectomy three years before the current presentation due to papillary thyroid cancer. She was not on regular follow-up, nor any specific therapy. On examination, she was agitated and violent. There were no signs of myxedema, and the physical exam was unremarkable. The initial workup showed a mild elevation in serum creatinine. Additional investigations revealed a high thyroid-stimulating hormone (TSH) of 56.6 mIU/L, low free T4<0.5 pmol/L, elevated creatine kinase of 3601 U/L, and urine dipstick positive for blood, suggestive of myoglobinuria. MRI of the head was unremarkable. We diagnosed her as a case of myxedema psychosis and mild rhabdomyolysis. She was started on oral thyroxine 100 mcg/day, fluoxetine 20 mg daily, and as-needed haloperidol. She was closely followed and later transferred to the Psychiatry Hospital for further management. Within one week, her symptoms improved completely, and she was discharged off antipsychotics with additional scheduled follow-ups to monitor TFTs and observe for any recurrence. Discussion and Conclusion. Myxedema psychosis is a rare presentation of hypothyroidism—a common endocrine disorder. Scarce data are describing this entity; hence, there is currently a lack of awareness amongst clinicians regarding proper identification and management. Moreover, the atypical nature of presentations occasionally adds to a diagnostic dilemma. Thus, any patient with new-onset psychosis should be screened for hypothyroidism, and awareness of this entity must be emphasized amongst clinicians and guideline makers.
Background. The shift of Graves’ disease (GD) to Hashimoto’s disease- (HD-) related hypothyroidism is well established. However, the opposite is rare. This is likely to the loss of critical thyroid mass available for stimulation by thyroid hormone receptor stimulating antibody, making this shift unusual. Herein, we report a young lady with a late shift from HD into GD and present a scoping literature review. Case presentation. We report a twenty-five-year-old lady with a sixteen-year-history of Hashimoto’s-related hypothyroidism stable on levothyroxine. While following in the clinic, she started developing thyrotoxic symptoms in the form of anxiety, weight loss, and palpitation. Physical examination was remarkable for mild exophthalmos. The thyroid function test confirmed hyperthyroidism. Levothyroxine-induced hyperthyroidism was initially suspected; however, the symptoms did not improve despite reducing and stopping levothyroxine. Subsequent workup confirmed the diagnosis of GD. Discussion and Conclusion. This case highlights a unique association that has significant diagnostic and management implications. This shift should be considered when hyperthyroidism persists despite reducing or stopping levothyroxine. The diagnosis is made utilizing antibody titers and radioiodine update scan. While the management depends on the disease’s stage and the treating physician preference, antithyroid agents can be used initially. Following up these patients is essential as the shift can be transient.
Renal cell carcinoma (RCC) is a primary tumor of the kidneys. It is characterized by the triad of flank pain, hematuria, and a palpable flank mass. However, most RCC patients present with a paraneoplastic manifestation of the disease. Stauffer's syndrome (a non-metastatic hepatic dysfunction) is a rare paraneoplastic manifestation associated with RCC. We report the case of a 30-year-old male, obese, who presented with hematuria and was found to have a right renal mass secondary to RCC. During his hospital stay, the patient developed acute hepatic dysfunction that resolved rapidly after tumor resection.
Background. Acute confusional migraine (ACM) is a rare variant of migraine, mainly prevalent in children and adolescents. It is not currently indexed as a distinct variant of migraine likely since only a few cases were reported in the adult population. We report a case of delayed ACM diagnosis in a young man and present a concise-related literature review. Case Presentation. A thirty-eight-year-old man with a past medical history of migraine, not on any treatment, presented with headaches accompanied by confusion. Over a two-year period before the current presentation, he experienced two episodes of confusion, which required hospital admission for evaluation: once mislabeled as a psychiatric illness and diagnosed as a migrainous infarct in the second hospitalization. In the current presentation, he reported a similar history of headache accompanied by confusion. The examination was remarkable for disorientation; otherwise, no focal deficit was elicited. Laboratory testing, cerebrospinal fluid, and neurological imaging were all unremarkable. His symptoms improved spontaneously within less than twenty-four hours, similar to his previous presentations. After two-year history of episodic confusion and after excluding other plausible causes of confusion, guided by proposed diagnostic criteria, we diagnosed him as a case of ACM. The patient remains well at the follow-up of two months after discharge. Discussion and Conclusion. ACM is a rare variant of migraine and is often a challenge for clinicians to diagnose appropriately. Until recent years, the disease was thought to be limited to children and adolescents. However, recently few reports also expanded the incidence of this entity to the adult population. There is a significant gap in knowledge about proper identification and treatment of this condition, leading to delayed or overlooked ACM diagnosis. Moreover, the recent edition of the International Classification of Headache Disorders (ICHD-3) does not account for this entity, thereby further adding to physicians’ lack of awareness regarding this migraine subtype. The authors emphasize that clinicians be aware of this entity and adequately utilize the existing proposed diagnostic criteria for ACM until standardized and validated tools are available. We also believe that this entity should be acknowledged in the subsequent migraine guidelines and classifications.
