Background: Here, we present a retrospective study conducted from 2009 to 2018, which showed the presence of unilateral uptake of radioactive tracer on 99m Tc thyroid scintigraphy scan in 15 patients with Graves’ disease. Materials and Methods: All these patients had either clinical features of Graves’ disease or elevated thyroid hormone levels along with ultrasonographic features, showing either normal thyroid gland or diffuse thyroiditis. The scintigraphic features revealed increased uptake in one lobe of the thyroid gland with the other lobe being normal. Results: Of the 15 patients, 13 were females and two were males. The mean age of the patients was 47 years with standard deviation of 3.4 years (range 26–70 years). Eight of the 15 patients had increased uptake on the right lobe and seven had increased uptake in the left lobe. Conclusion: This study shows that there exists an entity called unilateral Graves’ disease which should be further evaluated.

The association between the progestin only pill used for treatment of menstrual disorders and cerebral venous sinus thrombosis (CVST) has rarely been reported in the literature. This report describes a case of cerebral venous thrombosis following intake of norethisterone for menorrhagia secondary to polycystic ovary syndrome in a young woman with undiagnosed underlying hyperhomocysteinemia. A 24 year old married woman presented with acute onset of headache, vomiting and right focal seizures. MRI Cerebral venogram and CT Brain revealed thrombosed anterosuperior segment of superior sagittal sinus and haemorrhagic infarct in right frontoparietal region. The risk factors were acquired hyperhomocysteinemia, polycystic ovary syndrome and norethisterone for menorrhagia. The patient was treated with low molecular weight heparin, followed by warfarin, vitamin B 12 , vitamin B 6 and folic acid. She made a total recovery. Although venous thrombosis is usually linked to the ingestion of estrogen, rather than progestogen, this case illustrates that patients who are prescribed progestogen only pills for gynaecological disorders may develop thrombosis, especially if they have predisposing metabolic disorders.

The post-operative VAS, ODI, JOA, SF-36 scores showed a significant improvement from the preoperative ones. Postoperative thecal sac measurements showed a significant neural decompression substantiating the results of improvement in the functional assessment scores after surgery. The treadmill test is a quantifiable means of dynamic function. It may be considered as a useful tool for the assessment of functional impairment and for the correlation of thecal sac CSA with lumbar canal stenosis. A combination of functional scores, treadmill test, and thecal sac CSA may be included in the preoperative assessment of outcome in patients with LCS.

Objective: This prospective comparative study aimed to investigate the applied value of whole body 2deoxy-2[fluorine-18]fluoro-D-glucose positron emission tomography integrated with computed tomography ( 18 F-FDG PET/CT) in comparison to pelvic magnetic resonance imaging (MRI) in early cervical cancer patients.Material and methods: A prospective study was performed on 47 clinically early-stage cervical cancer patients evaluated with positron emission tomography/computed tomography (PET/CT) and MRI before surgery. The final postoperative histopathology report served as the reference standard. Both PET/CT and MRI images were analyzed and correlated with histopathologic findings concerning parametrial and lymph node involvement.Results: Sensitivity, specificity, and negative predictive value (NPV) of PET/CT were 33.3%, 81.8%, and 94.7%, respectively, for parametrium assessment. And the corresponding values of pelvic MRI were 33.3%, 63.6%, and 93.3%, respectively (PET/CT versus MRI, p > 0.05). The positive predictive value (PPV) of PET/CT (11.1%) was higher than MRI (5.9%) for parametrial assessment (p < 0.05). The sensitivity, specificity, PPV, and NPV of PET/CT were 75%, 83.7%, 30%, and 97.3%, respectively, for lymph node assessment. And the corresponding values of MRI were 75%, 81.3%, 27.3%, and 97.2%, respectively (PET/CT versus MRI, p > 0.05). There was no significant difference between MRI and PET/CT concerning stage migration (p = 0.4276). Conclusion:The PET/CT had no additional utility (compared to MRI) in the evaluation of local staging of clinically early cervical carcinoma patients.

Brown tumors seen in hyperparathyroidism are rare, non-neoplastic lesions because of abnormal bone metabolism, and they can mimic benign bone tumors or malignancy. Although biopsy is considered as the gold standard for diagnosis, it can be inconclusive. As the diagnosis of brown tumors is often challenging, a high index of suspicion is essential for diagnosis. We present a case of 21-year-old woman who presented with multiple painful bony lesions, which were initially misdiagnosed as fibrous dysplasia. Due to persistent bone pain and deterioration in her physical mobility, she was referred to tertiary care centre. After thorough clinical workup, she underwent Tc-99m methylene diphosphonate bone scintigraphy that raised strong clinical suspicion of hyperparathyroidism and brown tumors. Subsequently, Tc-99m-methoxy isobutyl isonitrile (MIBI) parathyroid scintigraphy revealed a solitary MIBI avid focal lesion, suggestive of left inferior parathyroid adenoma. Later parathyroidectomy was performed and histopathological examination confirmed it as atypical parathyroid adenoma.
