Imaging of salivary gland cancers derived from a sublingual gland herniated into the submandibular space: a report of three cases.

Sublingual gland herniation into the submandibular space through a mylohyoid muscle defect is a common anatomical variation; however, salivary gland cancers that arise from a herniated sublingual gland have not been described yet. Here, we report three patients with salivary gland cancers originating from a herniated sublingual gland. All tumors were detected as palpable submandibular masses, located anterior to the submandibular gland, medial to the mandible, and lateral to the mylohyoid muscle, with contact with the sublingual gland through a mylohyoid muscle defect. Intraoperative findings confirmed that the masses were derived from herniated sublingual glands. Pathological examination showed one case of mucoepidermoid carcinoma and two cases of adenoid cystic carcinoma. Imaging findings of the tumor location, in addition to the continuity with the sublingual gland through the mylohyoid muscle defect, are crucial for accurately diagnosing the tumor origin, which is essential for determining the appropriate clinical management.

Omental Hernia as a Potential Cause of False-Positive GI Bleeding on 99m Tc-RBC Scintigraphy.

ABSTRACT: Gastrointestinal bleeding scintigraphy is a noninvasive study used to determine the presence of active bleeding, localize the bleeding site, and estimate the bleeding volume for prognostic purposes in patients with suspected gastrointestinal bleeding. However, it is important to note that false-positive results can occur due to various reasons. In this case, we present the scenario of a middle-aged woman who exhibited symptoms of gastrointestinal bleeding and underwent 99m Tc-RBC scintigraphy. The imaging revealed an accumulation of radiotracer in the hypogastric region, which was later determined to be caused by an omental hernia on SPECT/CT images. The herniated structure caused congestion in the mesenteric vessels, leading to the accumulation of 99m Tc-RBC. This case highlights the significance of considering anatomical anomalies and nonbleeding pathologies when interpreting the 99m Tc-RBC scintigraphy results for gastrointestinal bleeding.

A rare cause of intestinal obstruction: right paraduodenal hernia.

Internal herniation is an extremely rare cause of intestinal obstruction. Paraduodenal hernias result from abnormal rotation of the bowel. Symptoms that may range from recurrent abdominal pain to acute obstruction may occur. If it is not diagnosed and treated in time, the disease may result in intestinal ischemia. This article aimed to present the diagnosis and treatment process of a 47-year-old male presenting with acute abdomen symptoms by evaluating retrospectively with the accompaniment of literature. During the abdominal exploration of the patient, nearly all of the intestines were observed to be herniated from the right paraduodenal region to the posterior area. The opening of the hernial sac was repaired primarily by reducing the intestinal bowel loops into the intraperitoneal region. The patient undergoing anastomosis by performing resection of the ischemic part after reduction of herniated bowel loops was discharged uneventfully on the post-operative 10th day. Paraduodenal hernia is a condition that should be considered in patients with abdominal pain and intestinal obstruction symptoms. Early diagnosis is of vital importance to prevent the complications which can develop.

Hérnia muscular: relato de caso diagnosticado pela ultrassonográfico / Muscular herniation: case report diagnosed by ultrasonography / Herniación muscular: reporte de caso diagnosticado por ultrasonografía

A hérnia muscular em extremidades é uma condição incomum e subdiagnosticada. A maioria das massas é indolor e assintomática. No entanto, em alguns casos, podem se tornar dolorosas após exercícios físicos prolongados. Neste relato de caso temos um paciente de 18 anos, queixando-se de abaulamento na perna esquerda após atividade física, com suspeita inicial de lipoma de extremidade A ultrassonografia identificou uma hernia muscular, destacando a importância de uma detecção precoce para que haja um tratamento adequado sem complicações, gastos desnecessários e diagnósticos equivocados.

Muscular hernia in extremities is an uncommon and underdiagnosed condition. Most masses are painless and asymptomatic. However, in some cases, muscle hernia can become painful after prolonged physical exercise. In this case report, we present an 18-year-old patient complaining of bulging in the left leg after physical activity, with initial suspicion of lipoma of the extremity. Ultrasonography identified a muscle hernia, highlighting the importance of early detection and leading adequate treatment without complications, unnecessary expenses, and misdiagnoses.

La hernia muscular en extremidades es una patología poco frecuente e infradiagnosticada. La mayoría de las masas son indoloras y asintomáticas. Sin embargo, en algunos casos, la hernia muscular puede volverse dolorosa después de un ejercicio físico prolongado. En este reporte de caso, presentamos a un paciente de 18 años que consulta por abultamiento en la pierna izquierda después de la actividad física, con sospecha inicial de lipoma de la extremidad. La ecografía identificó una hernia muscular, destacando la importancia de la detección temprana y conducir un tratamiento adecuado sin complicaciones, gastos innecesarios y diagnósticos erróneos.

Sonographic Demonstration of a Gastrocnemius Fascial Defect: A Rare Cause of Calf Pain / Demostración sonográfica de un defecto fascial del gastrocnemio: una causa rara del dolor de pantorrilla

ABSTRACT Fascial defects with muscular herniation are an uncommon, treatable cause of calf pain. Differential diagnosis includes deep vein thrombosis, compartment syndrome, soleus strain/tear, and muscle or subcutaneous tumour. In this case, sonography was more sensitive for diagnosis than magnetic resonance imaging.

RESUMEN Los defectos fasciales con herniación muscular son una causa poco frecuente y tratable del dolor de pantorrilla. El diagnóstico diferencial incluye trombosis venosa profunda, síndrome compartimental, distensión o desgarro del sóleo, y tumor subcutáneo o muscular. En este caso, la sonografía resultó más sensible para el diagnóstico que la tomografía por resonancia magnética.

Idiopathic Spinal Cord Herniation­Case Report

Idiopathic spinal cord herniation is a rare cause of progressivemyelopathy, especially in the absence of a history of spinal or surgical trauma. The radiological diagnosis ismade through a myelography or an MRI exam. The spinal cord is pushed anteriorly, buffering the dural defect and leading inmost cases to Brown-Séquard syndrome. The present study describes the case of a male patient with a clinical picture of progressive thoracicmyelopathy. In the clinical and radiological investigation, an idiopathic spinal cord herniation on the chest level was identified. During the surgery, the spinal cord was reduced to the natural site, taking its usual elliptical shape, and the dural defect was repaired with a dural substitute. The numbness of the patient improved, and the shocks in the lower limbs disappeared. A postoperative MRI confirmed the surgical reduction of the herniation and the restoration of the anterior cerebrospinal fluid (CSF) column to the spinal cord. The authors describe the clinical, radiological, intraoperative, and postoperative evolution.
