Appendiceal Diverticulitis Mimics Cecal Diverticulitis Diagnosed Preoperatively.

Appendiceal diverticulitis is an uncommon condition that clinically resembles acute appendicitis. However, it is an incidental finding in histopathological studies and is rarely diagnosed preoperatively by imaging studies. In this article, we present the clinical and imaging findings of a male patient presenting with right upper quadrant pain with a preoperative imaging diagnosis of appendiceal diverticulitis. He underwent laparoscopic appendectomy and confirmed the diagnosis of appendiceal diverticulitis. This is a rare preoperative diagnosis. The management is often like typical appendicitis which is appendectomy. It is important to differentiate it from diverticulitis of the small intestine or colon because these diseases usually require only conservative treatment.

A Review of Classification, Diagnosis, and Management of Hydrocele.

This article summarizes and updates a number of issues related to hydrocele including anatomy, embryology, classification, etiology, clinical manifestations, imaging findings, and management. Hydrocele is an abnormal collection of serous fluid between the parietal and visceral layers arising from the mesothelial lining of the tunica vaginalis that surrounds the testis and spermatic cord directly. Hydroceles result from an imbalance of secretion and reabsorption of fluid from the tunica vaginalis. Hydroceles can be divided into two types as primary and secondary. The diagnosis should be based on medical history, clinical manifestations, and imaging studies. Understanding the causes and types of hydroceles is useful for accurately diagnosing and treatment strategy. Hydroceles can be managed by conservative treatment, fluid aspiration, or hydrocelectomy.

Traumatic rupture of congenital cystic adenomatoid malformation mimicking traumatic pulmonary pseudocyst: a case report.

Thoracic trauma is commonly encountered in daily clinical practice; however, blunt thoracic trauma in patients with congenital cystic adenomatoid malformation (CCAM) is rare. CCAM rupture denotes a broad spectrum of manifestations on imaging and may be misdiagnosed as many other conditions. Consequently, this leads to inaccurate treatment and poor patient outcomes. We report the case of a girl with the initial diagnosis of a cavitary lung lesion that was likely a traumatic pulmonary pseudocyst or CCAM. The patient received medical therapy for 20 days; however, her condition did not improve. Subsequently, she underwent right lower lobectomy. Ruptured CCAM was confirmed during surgery and with histopathology. No complications occurred postoperatively, and the patient made a good recovery.

Review of diagnosis, differential diagnosis, and management of retroperitoneal lymphangioma.

Lymphatic malformation (LM) is the currently preferred term for what was previously known as lymphangioma. Retroperitoneal LMs are extremely rare, benign, cystic masses that arise from lymphatic vessels. They can be challenging to diagnose because they resemble other retroperitoneal cystic tumors. The development of treatment strategies for rare diseases, including retroperitoneal LM, requires the acquisition of new knowledge to enhance our understanding of the disease progression. Therefore, we present an update regarding fundamental and advanced issues associated with retroperitoneal LM. This review describes the epidemiology, histopathology, biomedicine, clinical manifestations, radiological features, differential diagnosis, and management of this lesion.

Left-sided acute appendicitis with congenital gastrointestinal malrotation.

We describe a 28-year-old man with acute appendicitis associated with gastrointestinal malrotation. The diagnosis was confirmed by a computed tomography scan, and he was treated by laparoscopic appendectomy without a Ladd procedure.

Safe endoscopic removal of ingested fish bone with esophageal perforation and impingement on the aortic wall.

Esophageal foreign bodies are common conditions that may lead to serious complications, such as esophageal perforation, neck abscess, mediastinitis, arterial injury, and lung damage. We report a rare case of esophageal fish bone impingement on the aorta that was managed without complication by endoscopic removal.

Uterine Arteriovenous Malformation: A Pictorial Review of Diagnosis and Management.

Uterine arteriovenous malformation (UAVM) is a rare condition and is classified as either congenital or acquired UAVM. Patients with UAVMs usually experience miscarriages or recurrent menorrhagia. Ultrasound is used for the initial estimation of UAVMs. Computed tomography and magnetic resonance imaging are noninvasive and valuable methods that provide good compatibility with digital subtraction angiography to support the diagnosis and treatment of UAVM. Timely diagnosis is crucial to provide appropriate treatment for alleviating complications. This article presents a pictorial and literature review of the current evidence of the diagnosis and management of UAVM.

Diffuse Gallbladder Adenomyomatosis with an Inflammatory Complication in an Adult.

Gallbladder adenomyomatosis (GA) is a benign alteration of the gallbladder wall. There are three types involved: segmental, fundal, and diffuse pattern; the last type is very rare. Ultrasound is the imaging method of choice for diagnosing that shows Rokitansky-Aschoff sinuses with cholesterol deposition creating comet-tail artifacts. Asymptomatic GA does not require surgery in case there are no malignant lesions defined by imaging diagnosis. We present the rare case of a 51-year-old man who was admitted to hospital due to abdominal pain concomitant with inflammatory syndrome. Imaging and histological findings were appropriate to diagnose diffuse GA and complication of cholecystitis.

Balo's Concentric Sclerosis Mimicking Tumor on Magnetic Resonance Imaging in a Young Patient.

Balo's concentric sclerosis (BCS) is a rare demyelinating disease known as Multiple Sclerosis (MS) lesion type III. It is a disease of the white matter of the brain characterized by a round lesion with variable concentric myelinated and demyelinated layers, appearing as "onion bulb." We present a case of BCS and discuss the imaging findings and management strategies of this disease. A 26-y-old male developed headache, weakness, and numbness of limbs. Magnetic resonance imaging (MRI) showed concentric lamellar like demyelinating lesions at the subcortical regions. The patient's neurological symptoms were consistent with the MRI findings.

Diffuse Pancreatic Carcinoma with Hepatic Metastases.

Pancreatic cancer is one of the seven leading causes of cancer death worldwide. Diffuse pancreatic carcinoma is very rare and underreported in the literature. Many advances have been made in the diagnosis and management of pancreatic cancer. However, most pancreatic cancer cases are detected at the terminal or metastatic stages. Therefore, timely diagnosis and therapeutic management are desirable goals for this disease. Although the proliferation of pancreatic cancer has been reduced by intervention, more work is needed to treat and prevent the disease. The purpose of this article is to present a case of a 54-year-old male with pancreatic cancer and to review the epidemiology, diagnosis, management, and prevention of pancreatic tumors in general as well as pancreatic carcinoma in particular.

A Rare Case of Diffuse Subependymal Periventricular Metastases from Small Cell Lung Carcinoma.

Small cell lung cancer, whose essence is neuroendocrine tumors, makes up proximately 14-20% of all lung cancer circumstances. Compared to non-small cell lung cancer, its clinical manifestation seems more positive and has a tendency to disseminate earlier in the process of its natural past. About 10% of patients present with brain metastases at the time of provisional diagnosis and sometimes all along the course of their disease, there will be 40-50% of developed brain metastases in addition. Although metastases in the brain parenchyma are often found in patients with advanced lung cancer, periventricular metastases are rare. We report one case of diffuse subependymal periventricular metastases from small cell carcinoma of the lung.

A Case of Arteriovenous Fistula After Kidney Trauma Mimicking Tumor.

Renal arteriovenous fistulas are rare complications of kidney injury that are usually caused by penetrating or blunt abdominal trauma, percutaneous or open biopsy, or surgery. We report a case of renal arteriovenous fistula after blunt abdominal trauma of a male patient who had traffic accidents. Computed tomography images show arteriovenous fistula lesion mimicking the tumor of the renal pelvis. Through this case, we present how to identify and avoid being confused in diagnosis as well as introduce its clinical manifestations, imaging, and treatment.

The dripping candle wax sign of melorheostosis.

Melorheostosis is a rare benign bone disease including dysostosis and sclerosis. Dripping candle wax presence is a common and typical sign of melorheostosis. This sign appears as irregular hyperostosis of the cortical bone which is likened to melted wax flowing down one side of a candle. It can sometimes cause pain, stiffness joint, or limitation of motion in the affected areas implicitly but mostly has no symptoms. It is usually observed on plain radiography; its appearance is generally hyperplasia on one side of the bone. We report a 33-year-old male who has an incidental diagnosis of melorheostosis post-trauma.

Intracranial Neurenteric Cyst in a Patient with Acute Unilateral Thalamic Infarction.

Intracranial neurenteric cysts are rare congenital lesions that can be mistaken for other lesions. They may contain mucous or serous glands, smooth muscle, lymphoid tissue and components of connective tissue. We report a case of neurenteric cyst which was detected accidentally by diagnostic imaging in the context of a thalamus infarct in a 45-year-old woman. We also discuss the results of a brief literature review and the pathological findings, imaging spectrum, evaluation and management of neurenteric cysts and thalamic infarctions. LEARNING POINTS: Neurenteric cysts are a rare type of foregut duplication cyst that are classified as intracranial or spinal and are associated with central nervous system abnormalities.Neurenteric cysts are usually benign and slow-growing, so conservative treatment can be provided if there are no symptoms.Thalamic stroke may be caused by arterial or venous infarction.Cardioembolism is the most common cause of thalamus infarction; variations in blood supply to the thalamus should be investigated in affected patients.
