An antenatally detected cystic lesion at the porta hepatis raises the suspicion of cystic BA. It is very important to differentiate this from choledochal cyst in infants with cholestasis and cystic lesions. This case report outlines the clinical presentation and radiological findings of an infant who had an antenatally detected intra-abdominal cystic mass, thought to be a choledochal cyst.

Research paper thumbnail of A 10-year review of thyroid lesions in a tertiary hospital in Abuja, Nigeria

Annals of Tropical Pathology, 2018

Introduction: Thyroid lesions are reputed to be the second most common of all endocrine lesions (... more Introduction: Thyroid lesions are reputed to be the second most common of all endocrine lesions (next to diabetes mellitus) and thyroid cancer is reported to be the 16th commonest cancer globally. This study reviewed the spectrum and scope of thyroid lesions encountered in a tertiary hospital in Nigeria over a decade. Setting: National Hospital Abuja (NHA) is a 450-bed tertiary public hospital located in the cosmopolitan city of Abuja the capital of Nigeria. Materials and Methods: This is a retrospective analytic study involving the entire thyroid specimen received in the department of histopathology from 1st January 2007 to 31st December 2016. Results: Our study demonstrated that thyroid pathologies are commoner in females than males with a ratio of 6:1. Papillary thyroid carcinoma and follicular adenoma are the commonest malignant and benign tumours respectively. Conclusion: Thyroid diseases are common cause of morbidity in our environment. The commonest malignant thyroid disease in NHA is the papillary carcinoma.

Research paper thumbnail of Differentiating acute epididymitis from testicular torsion using scrotal scintigraphy

Acute epididymitis is treated with a simple course of antibiotics while testicular torsion requires emergency surgical exploration to salvage the testis. The assessment of patients with acute scrotal pain is done mainly using color Doppler ultrasonography, which, however, requires skills and has limitations of being highly operator-dependent and uncomfortable to patients with scrotal pains because it may take too long to perform and often involves probe compression. Scrotal scintigraphy using 99m Tc-pertechnetate may provide an alternative reproducible, quick noninvasive and reliable nuclear medicine functional imaging technique that could be used in the evaluation of patients with acute scrotal pain. The aim of this study is to document our clinical experiences with the use of scrotal scintigraphy in differentiating acute epididymitis from testicular torsion in patients with acute scrotal pain. Material and Method: All scrotal scintigraphy performed in our institution between 2007 and 2015 were included in this study. Scrotal scintigraphy was performed after intravenous administration of 99m Tc-pertechnetate radiotracer and images were acquired using MEDISO dual-headed gamma camera. Acute epididymitis is diagnosed when there is increased blood flow on dynamic images and increased uptake around the region of the epididymis, while testicular torsion as decreased blood flow and photopenic area in the testis on dynamic and static images, respectively. The final diagnosis was documented based on relief of symptoms after a course of antibiotics or surgical exploration. Results: All patients were examined by urologist and only patients in whom the differentiation between acute epididymitis and torsion could not be made clinically were include in this study. A total of 21 patients were studied. There were 16 patients diagnosed with acute epididymitis and five patients with testicular torsion. Conclusion: Our study demonstrates that scrotal scintigraphy is a simple, accurate, and effective functional imaging technique that can differentiate acute epididymitis from testicular torsion in selected patients presenting with acute scrotal pain.

We report the case of a patient with metastatic tubulocystic RCC whose disease progressed through standard of care treatment for nonclear RCC. However, genetic analysis revealed a germline pathogenic variant of fumarate hydratase (FH) gene, and the patient had a sustained and durable response to pazopanib.

While 68Ga PSMA is a generator-derived PET radiopharmaceutical, SPECT/CT imaging using technetium-99m-labeled PSMA is now available as a suitable alternative. The aim of this study is to compare the pooled sensitivity, specificity, and accuracy of 99mTc-PSMA SPECT/CT and 68Ga-PSMA PET/CT in patients with prostate cancer. A search strategy was developed using text words, MeSH, and entry terms. The following databases will be searched: PubMed, African Journals Online (AJOL), Embase, Google scholar, ResearchGate, Cochrane Library, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science. Eligibility criteria include (a) all studies that are published or retrievable in English language, (b) observat...

The functional reticuloendothelial features of FNH can be demonstrated by scintigraphy. We present a case of breast cancer in whom fluorodeoxyglucose positron emission tomography/computerized tomography (CT) showed a homogenous hyperdense lesion in liver, which on Tc99m sulfur colloid single-photon emission computed tomography/CT was found to have increased focal tracer uptake suggestive of FNH.

Tc-99m methoxyisobutylisonitrile scintigraphy of both breasts showed a local area of abnormal uptake in the left breast in 5 min and 2 h. A skeletal scan showed very intense concentration of activity in the primary breast tumor in the left breast. A left mastectomy and an axillary dissection were performed. The predominant histologic type of the mass was an osteosarcoma, and the diagnosis of a primary osteogenic sarcoma of the breast was made. Primary osteogenic sarcoma of the breast is rare and represents less than 1% of all primary breast malignancies.

Its removal with rigid oesphagoscopy is challenging and carries a significant risk of oesphageal perforation. We present a case of an impacted meat bolus, which was successfully dislodged using barium swallow technique. The rarity of barium swallow in intervention radiology and the importance of creating awareness among radiologist and otolargyngologist of this therapeutic option are emphasized.
