Primary small intestine cancer: a challenge to diagnose

Abstract

INTRODUCTION Primary small intestinal neoplasms are rare tumors that are frequently small and challenging to diagnose. Small bowel cancers are uncommon in comparison to malignancies of other organs in the gastrointestinal tract accounting for just around 3% of cancers in this system. Small bowel tumors are typically clinically silent or exhibit nonspecific symptoms making an early diagnosis challenging and delaying until the patient reaches an advanced stage of the illness. Abdominal pain anorexia gastrointestinal bleeding and weight loss are all common clinical manifestations. The diagnosis can vary depending on the location of the lesion under study and typically includes laboratory tests radiographic imaging and endoscopic evaluation AIM OF THE STUDY Because primary and secondary small intestine neoplasms are infrequent, cause non-specific symptoms, and appear smaller at first, radiologists continue to encounter diagnostic hurdles. A CT scan is thought to help detect abnormalities in 70-80% of people with small bowel cancer. ... MR or CT enterography are more precise diagnostics for small intestine cancer staging while histology may have a major diagnostic value in daily routines. MATERIALS AND METHODS This case involves a 73-year-old female who presented to the doctor with complaints of stomach and epigastric pain that worsened after eating flatulence fatigue overall weakness constipation dark feces and a 13-kg weight loss. Colonoscopy and gastroscopy were inconclusive. CT scan revealed unequal infiltration of the small intestinal fragment's wall lumen constriction and new lumen development – suggesting intussusception. A regular CT scan was not informative enough prompting a follow-up MRI enterography for additional details. A thicker wall of the jejunum fragment and significantly expressed diffusion of the MR SI signal were noted. Pathological lymphadenopathy was suspected nearby with liver metastasis. During the surgery a section of the small intestine was resected along with five lymph nodes and liver metastasis. Histopathological examination confirmed the presence of an ulcerative tumor in the small intestine. ";N/A;N/A;N/A;N/A;"

CONCLUSIONS Because primary and secondary small intestine neoplasms are infrequent cause non-specific symptoms and appear smaller at first radiologists continue to encounter diagnostic hurdles. A CT scan is thought to help detect abnormalities in 70-80% of people with small bowel cancer. In any standard CT scan every part of the small intestine should be thoroughly analyzed because small tumors particularly uncommon ones in the small intestine could go undetected. Using intravenous and negative oral contrast material during multidetector-CT is an efficient approach for detecting small intestinal neoplasms. MR or CT enterography are more precise diagnostics for small intestine cancer staging while histology may have a major diagnostic value in daily routines.
