Partial Sheehan's syndrome with abdominal tuberculosis presented with pancytopenia and fluctuating thyroid profile: a case report.

Sheehan's syndrome is a well-recognized cause of panhypopituitarism secondary to pituitary apoplexy, followed by postpartum hemorrhage. Depending upon the degree of ischemic injury, it can be either partial or complete. Case presentation: We report an interesting case of a 35-year-old woman admitted to our hospital with complaints of abdominal distension, which was later presumed to be due to disseminated tuberculosis (TB) after excluding the possible differentials. During the treatment course, she was going through repeated attacks of hypovolemic shock and hypoglycemia due to adrenocortical insufficiency. This, along with the history of prolonged amenorrhea 4 years back due to severe postpartum hemorrhage in her last pregnancy, has led us to our diagnosis of partial Sheehan's syndrome. After 1 month of starting steroid and anti-TB therapy, it was quite surprising when she presented with features of pancytopenia and antitubercular drug-induced hepatitis. Discussion: Sheehan's syndrome may have a varying degree of presentation depending upon the degree of damage to the pituitary gland, which includes amenorrhea, lactation failure, adrenocortical insufficiency, hyponatremia, hypoglycemia, as well as pancytopenia in some rare instances The hormone panel especially the thyroid profile should be monitored carefully. Such cases are often challenging to deal with because of their varying degrees of presentation and the delay in diagnosis due to a lack of clinical suspicion. Conclusion: Therefore, we believe that this rare presentation of pancytopenia in Sheehan's syndrome with fluctuating thyroid profile and abdominal TB in the background will let clinicians approach such a rare disease differently.

Immune reconstitution inflammatory syndrome following disseminated TB with cerebral venous thrombosis in HIV-negative women during their postpartum period: a case report.

Immune reconstitution inflammatory syndrome (IRIS) is characterized by exuberant and dysregulated inflammatory responses to invading microorganisms. IRIS associated with tuberculosis (TB-IRIS) is widely known in HIV-positive patients after starting highly active antiretroviral therapy (HAART) therapy. However, IRIS has also been observed in solid organ transplant recipients, neutropenic patients, tumor necrosis factor antagonist recipients, and women during the postpartum period despite their HIV status. Case Presentation: We report an exceptional case of a 19-year-old HIV-negative lady who presented as IRIS following disseminated TB with cerebral venous thrombosis during her postpartum period. After 1 month of starting anti-TB therapy, we found a paradoxical worsening of her symptoms and further deterioration of radiological features showing extensive tubercular spondylodiscitis involving almost all the vertebral with extensive prevertebral and paravertebral soft tissue collections. Significant improvement was observed after 3 months of continuation of steroids along with an adequate dose of anti-TB therapy. Discussion: The possible mechanism that could explain this dysregulated and exuberant immune response in HIV-negative postpartum women would be rapidly changing immunologic repertoire, as the recovery of the immune system causes an abrupt shift of host immunity from an anti-inflammatory and immunosuppressive status toward a pathogenic proinflammatory state. Its diagnosis mostly depends on having a high degree of suspicion and ruling out alternative etiology. Conclusion: Therefore, clinicians should be aware of the paradoxical worsening of TB-related symptoms and/or radiological features at the primary site of infection or new location following an initial improvement in adequate anti-TB therapy despite HIV status.

A 15 year-old-girl with persistent leg pain diagnosed as a giant cell tumor of the tibial diaphysis: A case report and review of the literature.

INTRODUCTION: Giant cell tumor (GCT) is a benign bone tumor typically seen in epiphysis or metaphysis of mature long bones. Multiple large multinucleated giant cells dispersed among mononuclear spindle cells and monocytes constitute characteristic histological background of GCT of bone (GCTB). CASE PRESENTATION: A 15-year-old girl was admitted to our hospital with the complaint of pain and swelling in the left leg with difficulty in walking for 2 years. On X-ray of the left leg, osteolytic, expansile, eccentric lesion with sclerotic bone margin on the diaphysis of the tibia was seen suggesting oesteofibrous dysplasia. MRI demonstrated findings compatible with adamantinoma. The subsequent histology report was rather surprising, consistent with giant cell tumor of the bone. Extended intralesional curettage was done with the help of a high-speed burr followed by chemical cauterization and bone grafting. The patient was followed up for 2 years. The patient could walk normally without assistance or any signs of a recurrence. DISCUSSION: GCTB commonly affects people in their third and fourth decades of life and involves epiphysis of the long bone, but this is a case of diaphyseal GCT, at an age of 15 years. It is challenging to diagnose GCT, if present in an unusual location, unless confirmed by histopathological examinations. CONCLUSION: A multi-disciplinary approach is required to correctly reach the diagnosis of GCT when it happens to be in an uncommon location(s). Early diagnosis with appropriate treatment and long-term follow-up is mandatory for the successful outcome of the treatment.
