We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. CONCLUSIONS: PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.

We present a newborn with transient generalized osteosclerosis and negative genetic workup. The etiology of this condition is unknown. Given overlapping radiologic signs with severe forms of osteopetrosis, familiarity with this condition is crucial for correct diagnosis and management.

This case report delves into the intricate diagnostic journey of a 42-year-old male presenting with jaundice, abdominal distension, and ascites, where medical imaging, including CT scans and ultrasound, played a central role. Noteworthy radiological findings, such as irregular nodular margins and caudate lobe hypertrophy, illuminated the distinctive pathophysiology of cryptogenic cirrhosis. The study underscores the pivotal role of medical imaging in elucidating complex liver pathologies, emphasizing the relevance of radiological approaches in diagnosing cryptogenic cirrhosis and guiding comprehensive management strategies.

We present an unusual case of a woman in her early 50s with a slow-growing calvarial exostosis. Exostoses are bony spurs or osteomas extending outward beyond a bone\'s surface and may be benign or malignant. Calvarial exostoses are a less common bone tumor that can occur in the population. We present a case of a rare, slow-growing calvarial exostosis with a combination of mandibular tori and a congenital iris cyst. We discuss differentials of this exostosis and different syndromes that may cause it such as hereditary multiple exostoses and Gardner syndrome. The current article aims to spread awareness of this atypical presentation of exostoses and present our institution\'s surgical proposition for removing a calvarial exostosis to obtain a further histological analysis of its composition. As these masses may commonly be benign, a definitive diagnosis cannot be made through imaging alone to rule out more threatening conditions. We have addressed radiological findings and diagnostic and treatment options offered to the patient. The patient decided not to move forward with removing the mass and would continue to monitor and return should she notice any unusual or acute changes.

OBJECTIVE: To study the frequency of microbiological etiology of respiratory infections in patients with long COVID and their associated clinical and radiological findings.
METHODS: Nasopharyngeal swabs and sputum specimens were collected from 97 patients with respiratory illness stemming from long COVID. The specimens were assessed for their microbiological profile (bacteria and virus) and their association with the overall clinical and radiological picture.
RESULTS: In total, 23 (24%) patients with long COVID had viral infection (n = 12), bacterial infection (n = 9), or coinfection (n = 2). Microorganisms were detected at significantly higher rates in hospitalized patients, patients with moderate COVID-19, and patients with asthma (P < .05). Tachycardia (65%) was the most common symptom at presentation. A statistically significant number of patients with long COVID who had viral infection presented with cough and myalgia; and a statistically significant number of patients with long COVID who had bacterial infection presented with productive coughing (P < .05). Post-COVID fibrotic changes were found in 61% of cohort patients (31/51).
CONCLUSIONS: A decreasing trend of respiratory pathogens (enveloped viruses and bacteria) was found in long COVID. An analysis including a larger group of viral- or bacterial-infected patients with long COVID is needed to obtain high-level evidence on the presenting symptoms (cough, myalgia) and their association with the underlying comorbidities and severity.

Introduction Budd-Chiari syndrome (BCS) is a rare cause of ascites in children, and its clinical manifestation depends upon the extent and rapidity of the occlusion of hepatic veins. This study aimed to identify the clinical manifestations, causes, treatment options, and outcomes of BCS in children. Materials and methods A retrospective descriptive study of BCS in children under 15 years of age was conducted. This study was approved by the Pakistan Kidney and Liver Institute and Research Centre on June 23, 2023, with approval number 0128. The patients\' medical records from December 2020 to July 2023 were obtained from Sisoft Healthcare Information System. In this study, we employ a set of predetermined questions to retrieve relevant data retrospectively and then organise it in Excel spreadsheets. SPSS version 26 (Armonk, NY: IBM Corp.) was used to analyse the data. Categorical variables are shown as frequencies (%), while continuous variables are reported as mean±SD. Results Of 37 (n) patients diagnosed with BCS, 19 (51.35%) were male and 18 (48.65%) were female. The mean age of presentation was 9.8±4.1 years. Ascites are the predominant clinical manifestation (100%), followed by hepatomegaly (37.8%). A total of 45.9% of patients had deranged liver function tests. Chronic BCS is the predominant mode of presentation. Protein C deficiency was present in nine patients (24.3%), two patients (5.4%) had protein S deficiency and two patients (5.4%) had antithrombin III deficiency. Hepatic veins exhibited the highest incidence of obstruction (73.0%). Liver biopsies were done in 15 (40.54%) patients to determine the staging of fibrosis. Eight patients (21.62%) had undergone radiological interventions, two patients had liver transplants and the rest were treated with medications, including anticoagulants. Conclusion BCS can present in acute, subacute or chronic forms. Ascites and hepatomegaly should raise the suspicion of BCS in children. Common radiological findings are non-visualisation of the hepatic veins. BCS has a wide range of aetiologies and treatment options. Protein C deficiency is the most predominant procoagulant disorder. Radiological interventions during the acute and subacute forms of BCS usually have excellent results. Liver transplant remains the definite treatment.

UNASSIGNED: Capillary hemangioma is a rare benign hemangioma that occurs in the soft tissues of the skin, orbit, head, and neck. Intracranial cases, especially intraparenchymal cases, are extremely rare. In this study, we report the course of an intracranial parenchymal capillary hemangioma with left mild motor paresis and involuntary movements of the left upper extremity and was successfully treated by surgical resection, including radiological and pathological examinations.
UNASSIGNED: This is a case of a 60-year-old woman who presented with motor weakness and involuntary movement of the left upper extremity. Computed tomography and magnetic resonance imaging revealed the right frontal hemorrhagic mass lesion without enhancement of contrast medium. Cerebral digital subtraction angiography showed no vascular stain and abnormal arteriovenous shunt. Preoperatively, we diagnosed cavernous hemangioma with a hemorrhagic component located in the right motor cortex. Because this case was symptomatic, we performed a craniotomy and gross total resection of the right frontal lesion. The diagnosis of capillary hemangioma was made by histological examination, including immunohistological study.
UNASSIGNED: Because intraparenchymal capillary hemangiomas are difficult to diagnose with preoperative imaging, surgical treatment, and histopathological examination are important.

UNASSIGNED: Scurvy is an uncommon medical condition that affects children and is caused by an inadequate intake of vitamin C. This study presents the characteristics of patients with scurvy to raise awareness of the diagnostic process in developing countries where laboratory testing for vitamin C levels is often not available.
UNASSIGNED: A retrospective study was performed from period of 2018 to 2023. Data extraction includes patient age, sex, body mass index, constitutional symptoms, musculoskeletal, mucosal, cutaneous symptoms, other accompanying disorders, anemia, erythrocyte sedimentation rate, C-reactive protein, radiographic examination, vitamin C dose, and duration of treatment. Descriptive statistical analysis was performed in this study.
UNASSIGNED: Eighteen cases (17 males, 1 female) of scurvy were referred to our institution. Thirteen of 18 patients were misdiagnosed before referral. The median age at presentation was 4.5 (range, 2-11) years. The average body mass index was 13.93 ± 0.63 kg/m2. Half of patients had healthy weight. All patients presented with lower limb pain and 17 of 18 with refusal to walk. The median onset of diagnosis was 11 (range 4-48) weeks. White line of Frankel was described in all patients. Seven had anemia and 6 of 18 had increase in erythrocyte sedimentation rate and/or C-reactive protein levels. Only one patient had ascorbic acid levels evaluation before treatment since it was not readily available in our country. Treatment length varied from 2 weeks to 6 months.
UNASSIGNED: The diagnosis of scurvy is frequently delayed due to its extreme rarity in modern society and its ability to mimic numerous other conditions. In children presenting with limb pain and/or reluctance to walk and pathognomonic radiological findings, physicians must prioritize scurvy as a differential diagnosis. In scurvy, vitamin C supplementation is curative.

Chronic pulmonary aspergillosis (CPA) is a chronic progressive lung disease associated with a poor prognosis and a 5-year mortality rate of approximately 40-50%. The disease is characterized by slowly progressive destruction of the lung parenchyma, in the form of multiple cavities, nodules, infiltrates or fibrosis. CPA can be challenging to diagnose due to its non-specific symptoms and similarities with other respiratory conditions combined with the poor awareness of the medical community about the disease. This can result in delayed treatment even for years and worsening of the patient\'s condition. Serological tests certainly play a significant role in diagnosing CPA but cannot be interpreted without radiological confirmation of CPA. Although many data are published on this hot topic, there is yet no single definitive test for diagnosing CPA, and a multidisciplinary approach which involves a combination of clinical picture, radiological findings, microbiological results and exclusion of other mimicking diseases, is essential for the accurate diagnosis of CPA.

UNASSIGNED: Sumo wrestling is a traditional sport in Japan and becoming popular worldwide. Risk factors for lower back injuries in sumo wrestlers are heavier weight and larger body mass index (BMI). The mawashi (loincloth belt) worn by sumo wrestlers has been shown to restrict motion of the lumbar spine.
UNASSIGNED: To study the effects of sumo wrestling on the lumbar spine of high school and freshmen collegiate wrestlers, investigating the relationship between radiological findings, wearing of the mawashi during training, and lower back symptoms.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: From 2001 to 2017, a total of 197 members of the Japanese Sumo Federation (55 high school and 142 college freshman students) underwent routine radiographic examination of their lumbar spines and answered a questionnaire regarding lumbar symptoms. Wrestlers were classified as symptomatic and asymptomatic based on responses to a custom questionnaire. We used the unpaired t test to evaluate patient demographics and the chi square test to analyze radiographic lumbar spine abnormalities between symptomatic and asymptomatic wrestlers.
UNASSIGNED: The wrestlers\' mean height, weight, BMI, and duration in the sport were 174.0 ± 6.7 cm, 107.1 ± 22.4 kg, 35.2 ± 6.4, and 8.0 ± 3.2 years, respectively. There were 91 participants in the symptomatic group (46.2%) and 106 (53.8%) in the asymptomatic group. Ten wrestlers (5.1%) had osteophyte formations in the lumbar body; 8 of the 11 osteophytes (72.7%) appeared in the upper lumbar spine. Of the total, 48 wrestlers (24.4%) had deformities (Schmorl nodules) in the lumbar body, and 23 of 50 (46.0%) and 10 of 16 (62.5%) deformities were found in the upper lumbar spine of collegiate and high school wrestlers, respectively. Five wrestlers of the total 197 athletes (2.5%) had disc space narrowing in the lumbar body, with 3 of the 5 cases of disc space narrowing (60.0%) found in the upper lumbar spine. Spondylolysis in the lumbar body was found in 25 wrestlers (12.7%); 19 of the 91 symptomatic wrestlers (20.9%) had spondylolysis, compared with 6 of the 106 (5.7%) asymptomatic wrestlers (P = .0028).
UNASSIGNED: Almost one-third of sumo wrestlers had ≥1 abnormal radiological finding in the lumbar spine. There was a significant relationship between symptomatic wrestlers and spondylolysis.
