Summary
Idiopathic segmental infarction of the greater omentum (ISIGO) is a rare cause of acute abdomen. Tight pants can trigger ISIGO, necessitating combined physical exam and CT scan for diagnosis.
Area of Science:
- Gastroenterology
- Abdominal Imaging
- Surgical Pathology
Background:
- Idiopathic segmental infarction of the greater omentum (ISIGO) is an uncommon cause of acute abdominal pain.
- Diagnosis often relies on imaging and clinical presentation, as it is a rare condition.
Observation:
- A 75-year-old woman presented with acute left flank and lower abdominal pain.
- Physical examination revealed a linear scar on her abdominal wall, consistent with tight clothing.
- Computed tomography (CT) showed a heterogeneous density lesion distal to the constriction.
Findings:
- The patient's symptoms were attributed to ISIGO, uniquely triggered by wearing tight pants.
- Conservative management was successful.
- The case highlights the importance of considering unusual etiologies in ISIGO.
Implications:
- This case underscores the need for a thorough patient history, including lifestyle factors like clothing choices, in diagnosing ISIGO.
- Integrating physical examination findings with CT scan results is crucial for accurate diagnosis and appropriate management of ISIGO.
- Awareness of unique triggers like tight garments can aid clinicians in recognizing and managing this rare condition effectively.

01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:30Angina I: Introduction
Definition and Symptoms: Angina (angina pectoris) is chest pain or discomfort caused by myocardial ischemia, which occurs when the heart muscle receives insufficient oxygen-rich blood. It typically manifests as pressing, squeezing, or crushing sensations in the chest and may radiate to the shoulders, arms, neck, jaw, or back.Primary Cause: In a healthy state, the coronary arteries can dilate (widen) to increase blood flow and meet the increased oxygen demand during physical activity or...
