Preiser's disease in teenage female: A rare case report.

Preiser's disease or idiopathic avascular necrosis of the scaphoid is a rare condition where ischemia and necrosis of the scaphoid bone occurs without previous fracture. It is thought to be caused by repetitive micro trauma or side effects of drugs (e.g., steroids or chemotherapy) in conjunction with existing defective vascular supply to the proximal pole of the scaphoid. Wrist radiography or CT coupled with MRI is the imaging modality of choice in the diagnosis of this rare entity. Here, we report a case of Preiser's disease of the left wrist in a 17-year-old female patient who presented with left wrist pain of 2 years duration in the absence of trauma history or causative drug use. The diagnosis was made by wrist X-ray and MRI. She was managed by Physiotherapy and wrist immobilization using wrist and forearm support as well as NSAIDS (Meloxicam).

Fibrodysplasia ossificans progressiva: Two case reports.

Fibrodysplasia ossificans progressiva (FOP) is a rare and progressively debilitating disorder affecting 1 in 2 million individuals. It is characterized by the progressive ossification of soft tissues into ectopic bone and congenital malformations of the great toes. FOP leads to significant disability and can result in death due to thoracic insufficiency syndrome. These case reports examine the presentation, diagnosis, and management of FOP, highlighting the diagnostic challenges inherent in managing such rare conditions because of their unique clinical features. They underscore the need for increased awareness among healthcare practitioners to ensure early diagnosis and the implementation of effective management strategies.

Choriocarcinoma metastatic to both kidneys presenting with spontaneous renal hemorrhage: Case report.

INTRODUCTION: Choricocarcinoma is a highly malignant tumor. It metastasize commonly to the lungs. Metastasis to the kidney is uncommon, and bilateral metastasis is described rarely. Initial presentation with spontaneous bleeding of the renal metastatic tumor is scarce in the literatures. Here we present a case report of a choriocarcinoma patient with bilateral renal metastasis, presenting with spontaneous renal hemorrhage. CASE PRESENTATION: A 22 years old female presented to our emergency department with sudden onset of left flank pain. She has history of spontaneous abortion 02 years back with biopsy from the manual vacuum aspiration (MVA) showing molar pregnancy. Up on evaluation, patient was anemic. CT scan showed left renal bleeding tumor. Exploratory laparotomy and radical nephrectomy was done with the impression of bleeding renal cell carcinoma. The biopsy revealed choriocarcinoma. On her follow up, CT scan showed right renal and brain metastasis. She was given multi agent chemotherapy and her serum beta-hCG became undetectable after 01 year. DISCUSSION: Choriocarcinoma can be gestational or nongestational. The commonest route of metastasis is hematogenous. Presenting symptoms of renal metastasis can be hematuria, pain or more commonly incidental finding during work up. Choriocarcinoma is highly chemo sensitive. CONCLUSION: Bilateral renal metastatic choriocarcinoma is uncommon. Spontaneous renal hemorrhage as an initial presentation is even rare, and it can mimic a bleeding renal cell carcinoma. High index of suspicion is needed in a young women with recent history of spontaneous abortion.

Pattern of Radiographic and Sonographic Findings of Adult Patients Presented with Shoulder Pain at Tikur Anbessa Hospital, Addis Ababa, Ethiopia.

Background: Shoulder pain is one of the most common presentations in the orthopedic clinic. Multiple factors have been found to cause shoulder pain. Radiographs and ultrasound are widely available, relatively cheap modalities in assessing shoulder pain. The aim of this study is to assess the radiographic and sonographic imaging patterns of shoulder pain. Methods: A descriptive prospective cross-sectional hospital-based study was conducted at the Department of Radiology of Tikur Anbessa Specialized Hospital among patients with shoulder pain that came for imaging from August 2021-January 2022. Result: Of the 73 patients with shoulder pain included in the study, 67% were females while 33% males. The mean age was 51.7 years. Radiographs found pathology in 53% of the cases. Acromioclavicular joint osteoarthritis, greater tuberosity degenerative changes, rotator cuff calcification were common radiographic findings. Ultrasound detected pathologies in 87% of the cases. The common pathologies were rotator cuff pathologies, biceps tendon pathologies, acromioclavicular joint degeneration, greater tuberosity degenerative changes, subacromial subdeltoid bursitis, and adhesive capsulitis. There was a significant association between greater tuberocity degenerative changes and supraspinatous pathologies with age, greater tuberocity degenerative changes with supraspinatous pathologies, acromiohumeral distance of <7mm with supraspinatous pathology. Conclusion: Radiographs and ultrasound are valuable imaging modalities for shoulder pain. Low acromiohumeral interval, greater tuberosity degenerative changes, and acromioclavicular joint osteoarthritis are associated with rotator cuff tears. Rotator cuff pathologies are the most common pathologies observed in ultrasound. We recommend ultrasound to be second step after radiograph due to its low cost and wide availability.
