Fever not subsiding from past 2 days what could be the reason for 25 year old male

Reading File

Quick answer

A fever for 2 days in a 25-year-old can be caused by a common viral infection such as flu, COVID-19, or another respiratory virus. Other possibilities depend on symptoms and location, including throat/chest infection, urinary infection, gastroenteritis, dengue, malaria, or typhoid in relevant exposure areas.
Seek urgent medical care today if there is any of the following:
  • Trouble breathing, chest pain, severe headache, stiff neck, confusion, fainting, seizure
  • Persistent vomiting, severe abdominal pain, rash with fever, dehydration or very little urine
  • Temperature 39.4°C (103°F) or higher, or fever that is worsening
  • Recent travel, mosquito exposure, or possible dengue/malaria exposure
  • Weak immune system or serious chronic illness
For now:
  • Measure and record the temperature.
  • Drink fluids regularly and rest.
  • Paracetamol/acetaminophen can reduce discomfort or fever if he can normally take it. Follow the label and avoid combining products that also contain paracetamol. Avoid alcohol.
  • Do not start antibiotics without a clinician's assessment.
  • If fever lasts beyond 3 days, or there are significant local symptoms such as cough, sore throat, burning urination, diarrhea, rash, or body aches, arrange a medical examination and possible tests.
What is his highest temperature, and does he have cough, sore throat, body aches, rash, vomiting/diarrhea, pain while urinating, or recent travel/mosquito bites?

Patient Name: SHALINI NAGAR Age: 054Y/F Referring Physician: Yatharth Hospital MRI of the MRCP on September 04, 2026 at Izen Imaging and Interventions MRI of the UPPER abdomen including MRCP Clinical History : - Post cholecystectomy. Now complains of upper abdominal pain since Liver:The liver is normal in size and signal intensity. No focal lesion is seen. Mild prominence of the intrahepatic biliary radicals. The main portal vein is not visualized with multiple vessels in the periportal region suggestive of portal cavernoma. Gallbladder: The gall bladder is not seen post cholecystectomy status. CBD- The common bile duct is prominent measuring 7.5mm and shows gradual smooth tapering at its distal end. ill defined hypointensity in the distal CBD likely minimal sludge. No definite filling defect is seen within the common bile duct. Pancreas: The pancreas appears normal in size and signal intensity. The main pancreatic duct is not dilated. Spleen: The spleen is normal in size. No focal lesion is seen. Adrenals: Bilateral adrenals appear normal in size. Kidneys: Both kidneys are normal in size and position. Bilateral prominent extra-renal pelvis is noted. There is no focal lesion / hydronephrosis. Both ureters appear normal in caliber without any evidence of calculus. Bowel loops: The visualised small and large bowel loops do not show any obvious abnormality. Fluid:No free fluid is seen in the upper abdomen Lymph nodes: There are few subcentimeter sized lymph nodes in the retroperitoneum and mesentery. Sections through the lower chest appear normal. CONCLUSION: • Attenuated main portal vein with multiple vessels in the periportal region consistent with portal cavernoma. • Post cholecystectomy status with dilatation of common bile duct which could represent physiologic dilatation in background of post cholecystectomy status.

Reading File
This MRCP report has several separate issues that should be reviewed with a gastroenterologist/hepatologist, especially because there is upper abdominal pain and a possible bile-duct narrowing.
  1. Portal cavernoma - the main portal vein is not clearly seen and has been replaced by collateral veins. This usually reflects longstanding portal-vein obstruction.
  2. Bile-duct dilatation after gallbladder removal - CBD measures 7.5 mm. Mild widening can occur after cholecystectomy, but symptoms and liver tests determine whether it needs intervention.
  3. Possible distal CBD issue - minimal sludge is suspected and a short distal stricture cannot be excluded, though there is no definite stone on MRCP.
  4. Next investigations and decisions - liver function tests and specialist assessment; ERCP may be considered if liver tests, jaundice, pain pattern, or other findings suggest ongoing obstruction.
  5. Warning symptoms - fever/chills, jaundice, dark urine, pale stools, escalating pain, vomiting, confusion, or low blood pressure can indicate biliary infection/obstruction and need urgent evaluation.
At a high level, the scan does not show a liver mass, pancreatic mass, pancreatitis, obvious CBD stone, ascites, or kidney obstruction. The two findings needing follow-up are portal cavernoma and the mildly dilated CBD with possible distal narrowing. Whether ERCP is appropriate cannot be decided from the report alone: it depends particularly on bilirubin, ALP, GGT, AST/ALT, symptoms, and prior history of portal-vein thrombosis/liver disease. Portal cavernoma can make biliary procedures more complex, so it is best planned by an experienced GI/hepatobiliary team.

ASGE guideline biliary strictures ERCP tissue diagnosis cholangitis indications

ERCP is generally needed when a suspected common bile duct (CBD) stricture is likely to be causing obstruction, infection, or requires tissue sampling and treatment. It is not usually done only because an MRCP says that a stricture “cannot be ruled out,” since ERCP has risks such as pancreatitis, bleeding, infection, and perforation.
For this report, ERCP is more likely to be appropriate if any of the following are present:
  • Abnormal liver tests suggesting obstruction, especially raised bilirubin, alkaline phosphatase (ALP), and GGT, with or without raised AST/ALT.
  • Jaundice, dark urine, pale stools, itching, or progressively worsening upper abdominal pain.
  • Cholangitis, meaning biliary infection: fever or chills plus upper abdominal pain and jaundice, or blood tests/imaging suggesting infection. This requires urgent hospital assessment and bile-duct drainage, commonly ERCP, generally within 48 hours. The ASGE cholangitis guideline supports ERCP-based drainage in this setting.
  • A convincing obstruction on imaging: increasing duct dilatation, a definite stone/sludge causing blockage, or a clear narrowing with upstream bile-duct dilatation.
  • A stricture that remains unexplained and raises concern for malignancy or needs clarification. ERCP can allow brushings and forceps biopsies, and may include cholangioscopy in specialist centers. The ASGE stricture guideline recommends tissue sampling approaches when ERCP is being performed for an undetermined biliary stricture.
  • Need for treatment: removal of obstructing sludge/stone, balloon dilatation of a benign narrowing, or placement of a stent to restore bile flow.
When ERCP may not be needed immediately:
If liver tests are normal, there is no jaundice or fever, pain is mild/non-progressive, and MRCP only shows mild smooth tapering with no definite stone or mass, a gastroenterologist may first choose observation with repeat liver tests and/or EUS (endoscopic ultrasound). EUS is particularly useful for assessing the distal CBD, ampulla, pancreas, tiny stones, or a subtle mass, and can sometimes avoid an unnecessary ERCP.
For this MRI specifically:
  • CBD 7.5 mm can be a physiologic post-cholecystectomy finding.
  • No definite CBD stone was seen.
  • The scan raises but does not establish a distal CBD stricture.
  • The portal cavernoma is important: it can cause biliary compression or varices around the bile duct and can make ERCP more technically complex. ERCP, if needed, should be planned by an experienced gastroenterology/hepatobiliary team.
Next practical step: obtain or review bilirubin (total/direct), ALP, GGT, AST, ALT, CBC, and possibly lipase. Arrange a gastroenterology/hepatology consultation soon. Go to emergency care immediately for fever/chills, jaundice, worsening severe pain, vomiting, low blood pressure, confusion, or marked weakness.
