Summary

Thyroid eye disease (TED) is the most common extra-thyroidal manifestation in Graves’ disease (GD). Additional/concurrent/synchronous pathologies may be present, especially in elderly patients who present with atypical features such as non-axial (or eccentric) proptosis, absence of lid lag and restricted superior extra-ocular movements. A 70-year-old female presented with progressive proptosis of her left eye and diplopia. She was diagnosed with GD a year prior and initiated on carbimazole. On examination, she had eccentric proptosis, restricted superior extra-ocular movements and a palpable mass in the supero-temporal quadrant of the left eye. Her T3 (1.33 ng/mL) and T4 (8.85 µg/dL) were normal with carbimazole. Thyroid-stimulating hormone (TSH)-receptor antibody was positive (3.15 IU/L, reference range <1.75). MRI revealed an enhancing lesion infiltrating the left superior rectus, with concurrent characteristic muscle belly involvement bilaterally. Orbital biopsy showed atypical lymphoid cells (CD20+), suggesting marginal zone lymphoma. CT thorax and abdomen, fluorodeoxyglucose-positron emission tomography and bone marrow examination were normal. The patient was administered orbital radiotherapy for her localised lymphoma and carbimazole was continued. TED is the most common cause of orbital involvement overall and in GD. However, additional or alternative pathology may be present which requires evaluation. MRI can be a useful adjunct in these patients. Orbital lymphoma needs to be staged with workup for disseminated disease. Radiotherapy is the treatment of choice for localized disease. The index case provides evidence for synchronous presentation of dual pathology and highlights the importance of astute clinical examination as well as keeps a low threshold for MRI in selected cases.

Learning points

  • Thyroid eye disease can co-exist with other ocular pathology, especially in elderly individuals.

  • Eccentric proptosis, absent lid lag and restriction of eye movements (suggesting tendon involvement) should alert towards the presence of alternative pathology.

  • Orbital imaging using MRI not only has greater sensitivity in diagnosing radiologically bilateral disease in patients who have unilateral involvement clinically but is also useful to identify concurrent neoplasms.

Summary

A 21-year-old female patient recently diagnosed with severe hypothyroidism was found to have a large ovarian cyst. In view of the large ovarian cyst, she was advised to undergo elective laparotomy in the gynaecology department. She was further evaluated in our medical out-patient department (OPD), and elective surgery was withheld. She was started on thyroxine replacement therapy, and within a period of 4 months, the size of the cyst regressed significantly, thereby improving the condition of the patient significantly. This case report highlights the rare and often missed association between hypothyroidism and ovarian cysts. Although very rare, profound hypothyroidism that can cause ovarian cysts in an adult should always be kept in the differential diagnosis to avoid unnecessary ovarian surgery.

Learning points

  • Hypothyroidism should be considered in the differential diagnosis of adult females presenting with multicystic ovarian tumours.

  • Adequate thyroid hormone replacement therapy can prevent these patients from undergoing unnecessary and catastrophic ovarian resection.

  • Surgical excision should be considered only when adequate thyroid replacement therapy fails to resolve ovarian enlargement.

  • In younger women with ovarian cysts, it is also desirable to avoid unnecessary surgery so as to not compromise fertility in the future.

Summary

We describe the clinical presentation, diagnostic and management issues in five cases of non-islet cell tumor hypoglycemia (NICTH), diagnosed at a tertiary care institute over a period of 15 years. The clinical, laboratory, and histopathological findings of these patients along with diagnostic utility of IGF2:IGF1 ratio are discussed. The mean age of presentation was 52 years, with a male predominance (3:2). Three patients presented with recurrent episodes of fasting hypoglycemia and it was detected in other two patients during hospitalization. Two patients had acromegaloid features that regressed following treatment. One patient had hypokalemia. Low levels of insulin, C-peptide, GH, and IGF1 were invariably found in all. The IGF2 level was elevated in only one patient; however, IGF2:IGF1 ratio was more than 10 in four of the five patients. The mean tumor size was 16.4 cm and mean weight was 3.6 kg. Four patients had mesenchymal tumors and one had epithelial tumor. NICTH is a rare cause of hypoglycemia. Hypoinsulinemic hypoglycemia with low IGF1 and IGF2:IGF1 ratio more than 10 is suggestive of this entity.

Learning points

  • NICTH should be considered in patients presenting with tumor of mesenchymal origin and hypoglycemia.

  • Hypoinsulinemic hypoglycemia with low IGF1 is a strong biochemical evidence of NICTH.

  • IGF2:IGF1 ratio of more than 10 is a complementary investigation in the absence of an assay facility for IGF2.

Summary

Insulin autoimmune syndrome (IAS) is a rare cause of hyperinsulinemic hypoglycaemia, which is known to occur in association with the use of sulfhydryl-containing drugs and autoimmune disorders. We describe a patient with hitherto an unreported association of IAS with ankylosing spondylitis. We have also performed and described a simplified method of polyethylene glycol (PEG) precipitation of an insulin bound antibody in the serum.

Learning points

  • IAS should be considered in differential diagnosis of endogenous hyperinsulinemic hypoglycaemia.

  • Ankylosing spondylitis can be associated with IAS apart from several other autoimmune diseases.

  • Very high serum insulin levels (100–10 000 μU/ml) are frequently seen in IAS.

  • When faced with very high serum insulin before suspecting insulinoma, it is advisable that PEG precipitation of serum be done to identify antibody bound insulin.

  • A clinical suspicion of IAS can avoid expensive imaging and unnecessary surgery in affected patients.

Summary

Spontaneous diabetic muscle infarction (DMI) is a rare and under diagnosed complication of diabetes mellitus. Clinically it presents with acute to subacute onset swelling, pain and tenderness of muscle(s) without systemic manifestations. MRI is helpful in diagnosis, exclusion of other causes and for localization of affected muscle for biopsy in atypical cases. Muscles of the thighs are commonly affected in diabetic myonecrosis (DMN). Here we present the summary of four cases seen in the last 3 years in a tertiary care centre with simultaneous or sequential involvement of multiple groups of muscles or involvement of uncommon sites. All these patients had advanced duration of diabetes with microvascular complications and poor glycemic control. Conservative management including rest and analgesics is the treatment of choice. Short-term prognosis is good but there may be recurrence.

Learning points

  • A high index of suspicion is required for the diagnosis of DMN which can avoid inadvertent use of antibiotics.

  • Acute–subacute onset severe focal muscle pain in the absence of systemic symptoms in a female patient with long-standing diabetes with microvascular complications suggests DMI.

  • MRI is the most sensitive test for diagnosis.

  • Muscle biopsy should be reserved for atypical cases.

  • Conservative management including rest and analgesics has good outcome.

  • Improvement usually occurs within 6–8 weeks, but there may be recurrence.

Summary

Ovarian steroid cell tumors are very rare functioning sex-cord stromal tumors. They comprise <0.1% of all ovarian tumors. Previously designated as lipoid cell tumors, one-third of these tumors are considered malignant with the mean age of presentation at around 40 years. We present a case of a 28-year-old female with 2-year history of hirsutism, virilization, and amenorrhea. She was diagnosed with left ovarian tumor, for which she underwent left salpingo-oophorectomy. Histopathology revealed not otherwise specified subtype of steroid cell tumors. The patient resumed menses 2 months after the features of masculinization regressed. Within 1 year of surgery, the patient successfully conceived a full-term baby without any complications. In a young female, the neoplastic etiology of a rapid virilization or menses changing should always be kept in mind. Though commonly observed in adult females, steroid cell tumors have very good surgical outcomes if age at presentation is less and tumor is unilateral, and there are no evidences of bilateral malignancy. Bilateral salpingo-oophorectomy is not required.

Learning points

  • In a case of severe rapid hirsutism and virilization with serum testosterone level more than 200 ng/dl or more than threefold of the normal range, neoplastic conditions should always be suspected.

  • Steroid cell tumor in young women without evidence of malignancy on histopathology has excellent surgical outcomes.

  • Unilateral salpingo-oophorectomy is the surgery of choice.

  • As the frequency of bilateralism is only 6%, prophylactic unaffected side oophorectomy need not be done.

Summary

Combined pituitary hormonal deficiency (CPHD) is a rare disease that results from mutations in genes coding for transcription factors that regulate the differentiation of pituitary cells. PROP1 gene mutations are one of the etiological diagnoses of congenital panhypopituitarism, however symptoms vary depending on phenotypic expression. We present a case of psychosis in a 36-year-old female with congenital panhypopituitarism who presented with paranoia, flat affect and ideas of reference without a delirious mental state, which resolved with hormone replacement and antipsychotics. Further evaluation revealed that she had a homozygous mutation of PROP1 gene. In summary, compliance with hormonal therapy for patients with hypopituitarism appears to be effective for the prevention and treatment of acute psychosis symptoms.

Learning points:

  • Patients with PROP1 gene mutation may present with psychosis with no impairment in orientation and memory.

  • There is currently inadequate literature on this topic, and further study on the possible mechanisms of psychosis as a result of endocrine disturbance is required.

  • Compliance with hormonal therapy for patients with hypopituitarism appears to be effective for prevention and treatment of acute psychosis symptoms.
