Scrub typhus, a rare of cause of fulminant hepatic failure: A common disease with uncommon presentation

Scrub typhus (bush typhus) is a potentially lethal mite-borne, acute febrile infectious illness caused by Orientia tsutsugamushi, reported precipitating frequent outbreaks in the Asia-pacific belt. Usual presentation after a median incubation period of 10–14 days, stretches from pathognomonic eschar, high-grade fever, centrifugal skin rash, jaundice, regional lymphadenopathy to frontal headache, nevertheless complicated at times with myocarditis, acute respiratory distress syndrome, acute kidney injury, encephalitis, and shock. Although patients with scrub typhus invariably do display mild liver injury, fulminant hepatic failure (FHF) is rarely reported. We describe herein, a case of FHF in an elderly male that responded well to antibiotics. Early diagnosis and sensitive antibiotic administration aids in mortality prevention of the former.

Cystic retroperitoneal metastasis from testicular seminoma, radiologically mimicking as lymphangioma

Background Retroperitoneal nodal metastasis in a primary testicular tumor is not uncommon and usually presents as solid or solid-cystic nodal masses. A completely cystic appearance with fluid attenuation or fluid signal intensity on computed tomography (CT) and magnetic resonance imaging (MRI), respectively, is an uncommon presentation. There are many case reports of different types of cystic retroperitoneal masses; however, to our knowledge, metastatic retroperitoneal cystic masses showing fluid attenuation/fluid signal intensity on CT/ MRI secondary to primary testicular seminoma masquerading as cystic lymphangioma has been rarely reported in the medical literature. Our case report reports a case of a metastatic retroperitoneal cystic mass in a known case of testicular seminoma patient, which was misdiagnosed as cystic lymphangioma initially based on imaging. Case presentation A 55-year-old—patient presented to our hospital with abdominal pain, which was on and off in character. The patient underwent routine ultrasound abdomen, CT and MRI, which revealed multiple cystic lesions in the retroperitoneum. Initially, a provisional diagnosis of cystic lymphangioma was made based on the utterly cystic nature of the lesion and the presence of calcification. However, fine-needle aspiration cytology (FNAC) confirmed the metastatic origin of the lesion and was strengthened by the previous clinical history of orchidectomy. Conclusion The treatment strategy for cystic retroperitoneal masses varies depending on the cause and its nature, so differentiation between the cystic masses is essential. Metastasis should also be kept in the differentials in all cystic retroperitoneal masses. Moreover, clinical history and FNAC can assist in making the correct diagnosis.

Extranodal Non-Hodgkin Lymphoma: A Rare Presentation Involving the Pancreas

Non-Hodgkin lymphoma (NHL) is a cancer of the immune system, and accounts for 90% of all lymphomas. When lymphoma is discovered outside of the immune system, it is considered extranodal lymphoma. Any organ can be the primary site of NHL, with the gastrointestinal tract being the most common site of involvement. This case study explores the sonographic discovery of an uncommon presentation of NHL with an extranodal mass originating from the pancreatic body and tail, and further extending into the splenic hilum.

Unusual intracranial suppuration: illustrative cases

BACKGROUND Intracranial suppuration (ICS) is a rare complication that can arise from various disease processes and is composed of brain abscess, extradural empyema, and subdural empyema. Although significant progress has been achieved with antibiotics, neuroimaging, and neurosurgical technique, ICS remains a serious neurosurgical emergency. An uncommon presentation of ICS is sterile ICS, which has yet to be fully elucidated by clinicians. The authors present 2 cases of unusual sterile ICS: a sterile subdural empyema and a sterile brain abscess. OBSERVATIONS Both patients underwent surgical treatment consisting of craniotomy to evacuate the pus collection. The blood cultures from both the patients, the collected empyema, and the thick capsule from the brain abscess were sterile. However, the necrotic brain tissue surrounding the abscess contained inflammatory cells. The authors’ review of the literature emphasizes the rarity of sterile ICS and substantiates the necessity for additional studies to explore this field. LESSONS Sterile ICS is a disease entity that warrants further investigation to determine appropriate treatment to improve patient outcomes. This study highlights the paucity of data available regarding sterile ICS and supports the need for future studies to uncover the etiology of sterile ICS to better guide management of this condition.

Upper Gastrointestinal Manifestations of Crohn’s Disease: Differential Diagnosis and Treatment of an Uncommon Presentation of Crohn’s Disease

ABSTRACT Esophagogastroduodenoileal involvement of Crohn’s disease (CD) is uncommon; less than 5% of adult patients will suffer from this condition, although this diagnosis is likely underestimated given the lack of routine evaluation of the upper gastrointestinal tract in the absence of symptoms. An interesting differential, including sarcoidosis, eosinophilic gastroenteritis, tuberculosis, and Brunner’s gland hyperplasia, should be considered. The consequences of this diagnosis can have profound impacts on the military career of a soldier. Learning objectives of this case report include workup, differential, diagnosis, and treatment of esophagogastroduodenoileal involvement of CD, as well as discussing the psychological effects of this diagnosis and impact on an individual’s military career.

A Case of Thrombotic Vasculopathy in the Setting of High-Dose Hydroxyurea Use

This case study describes the presentation of a 76-year-old male with a past medical history that included atrial fibrillation, essential hypertension, coronary artery disease status post cardiac stent placement, heart failure, hyperlipidemia, thyroid cancer (with thyroid resection resulting in hypothyroidism), prostate cancer status post brachytherapy (in remission), and a history of JAK2-positive myeloproliferative disease. He presented with painful areas of hyperpigmentation appearing as purple discoloration to his neck, lower abdominal skinfold, and bilateral groin areas that progressed to painful ulcerations a few weeks after a myocardial infarction. Due to the patient’s multiple medical conditions and uncommon presentation of wounds, a multidisciplinary team was involved in his care. Differential diagnosis included antiphospholipid syndrome, symmetrical drug-related intertriginous and flexural exanthema, warfarin-induced necrosis, cutaneous thrombotic vasculopathy, myeloproliferative disorder, and high-dose hydroxyurea therapy. It was determined by the authors that the high-dose hydroxyurea therapy was the cause of the wounds. Because of the patient’s initial health status, treatment of the wounds included use of collagenase and sodium hypochlorite solution to reduce the risk of infection and attempt to promote autolytic debridement until surgical wound debridement could be done. The patient required multiple hospital stays, but ultimately his health status improved and the wounds resolved with the assistance of the combined efforts of the multidisciplinary team to diagnose and treat this complex patient and his uncommon wound presentation.
