Insights

A patient with a history of lymphoma and bone marrow transplant experienced rectal bleeding and fever. Imaging revealed pneumatosis cystoides intestinalis, a rare condition of gas cysts in the colon.

Area of Science:

  • Gastroenterology
  • Oncology
  • Hematology

Background:

  • A 49-year-old female with a history of stage IV diffuse large B-cell lymphoma and graft-versus-host disease post-bone marrow transplant presented with acute symptoms.
  • The patient had undergone a bone marrow transplant, a significant factor in her complex medical history.

Observation:

  • Presented with a 12-hour history of painless per rectal bleeding and fever.
  • Physical examination revealed a soft, distended abdomen.
  • Laboratory results indicated thrombocytopenia and hypokalaemia.

Findings:

  • Computed tomography (CT) of the abdomen and pelvis demonstrated pneumatosis cystoides coli, gas-filled cysts within the colon wall, extending from the ileocaecal junction to the mid-transverse colon.
  • The CT findings were described as bizarre, highlighting the unusual presentation of this condition.

Implications:

  • Pneumatosis cystoides coli can present with diverse gastrointestinal symptoms, including rectal bleeding.
  • Management in this case was conservative, focusing on supportive care including intravenous antibiotics, fluid resuscitation, and electrolyte correction.
  • This case underscores the importance of considering rare gastrointestinal pathologies in immunocompromised patients with complex histories.

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Pleural Effusion I: Introduction

Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's...

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
