Brief Clinical History: Non Hodgkin's Lymphoma.
Operation (01.05.2024): Left superficial parotidectomy.
Histopathology (06.05. 2024): Chronic sialadenitis.
Lymph node: Non Hodgkin's lymphoma.
Immunohistochemistry (12.05.2024): CD20, CD3, CD10: positive, BCL6, BCL2, CyclinD1,
CD2: negative, ki67: positive, suggestive of follicular lymphoma, grade III.
Immunohistochemistry (16.05.2024): Favor diffuse large B cell lymphoma, activated B cell
type.
Radiotherapy : Not applied.
Chemotherapy : Not applied.
Blood Sugar: 5.28 mmol/L.
S. Creatinine: 61 mmol/L
Procedure: Whole body FDG PET scan was acquired from vertex to mid thigh in a whole-body PET-CT scanner (128 Slice GE Discovery VCT), one hour after intravenous injection 9.59 mCi (355-MBq) of 8F-FDG. High resolution contrast CT scan was also obtained of the same area. Oral contrast was administered for bowel pacification over 90 min. before the scan.
VUE point HD algorithm and slices were reformatted into transaxial, coronal and sagittal views.
Semi-quantitative estimation of FDG uptake was performed by calculating SUVmax value, corrected for dose administered and body weight (g/ml).
Summary of the Findings
Brain:
Visualized part of cerebral and cerebellar hemispheres are uniform with normal physiological tracer distribution in the brain parenchyma. The ventricular system appears to be normal in in the brain.
diameter and no mass lesion or midline shifting. No focal lesion or abnormal FDG uptake noted
where clinically indicated.
Note: All brain metastases may not be apparent on a PET/CT sean and a MRI can be performed

Evidence of left superficial parotidectomy, no significant focal or diffuse FDG uptake at the site of surgery
Normal physiologic uptake noted in the nasopharynx, oropharynx, hypopharynx and larynx.
Parotid and submandibular glands demonstrate normal metabolic activity.
Thyroid gland: mildly enlarged & shows homogenous pattern on CT, no abnormal
FDG uptake is seen in the thyroid.
No significant cervical and supraclavicular lymphadenopathy is noted
No abnormal FDG uptake in the head and neck region.
Thorax: (Mediastinal mean SUV: 1)
Both lung fields: showing normal attenuation. The mediastinal vascular structures are well opacified with I/V contrast. The trachea and main bronchi appear normal. No parenchymal focal or diffuse lesion could be detected.
Multiple prominent subcarinal, aortopulmonary & left bronchopulmonary lymph nodes with mild FDG uptake (SUVmax: 5.8), largest one 10 mm in SA dia)
No pleural thickening or effusion is seen.
Axillary lymph nodes are not enlarged.
No other abnormal FDG uptake noted in the lung parenchyma, mediastinum or Axillary region.
Breasts: no soft tissue mass or abnormal tracer uptake in either breast region.
Heart: normal in position and all cardiac chambers appear normal, no pericardial effusion.
Normal physiological FDG uptake in the myocardium.
Great vessels are normal in size & relation, no abnormal tracer uptake in its wall.
Abdomen and pelvis: (Hepatic mean SUV: 1.2)
Liver: Mildly enlarged (15.5 cm along its CC span) and uniform parenchymal density. No focal area of altered attenuation or abnormal enhancement is noted. Vascular structures are normally visualized and distributed normally. No abnormal uptake of FDG is noted in the liver parenchyma. The intrahepatic biliary radicles are not dilated.
Gall bladder: normal in size & shape with normal wall thickness.
No calculus or soft tissue
mass within the lumen, no pericholecystic collection; no abnormal FDG uptake.
Pancreas: Paripancreatic fat planes are preserved. No evidence of cyst, calcification, diffuse or focal parenchymal lesion could be detected. No abnormal FDG uptake in the pancreas.

Spleen: mildly enlarged (11 cm along its long axis) with uniform parenchyma. No focal or diffuse lesion is noted, splenic hilar vessels are not significantly dilated; no abnormal FDG uptake.
Adrenal glands: appear normal in size, shape & position with normal attenuation pattern on CT.
No abnormal FDG uptake is noted.
Kidneys: appear normal in position and attenuation pattern, relatively larger (RK: 11 cm & LK: 11.5 cm in its bipolar length). No scan evidence of calculus, any mass lesion, cyst or hydronephrosis is noted. Physiological tracer distribution in both kidneys & ureters.
Urinary bladder: well distended and normal wall thickness, no calculus or intravesical mass is noted, no abnormal FDG uptake.
Prostate gland: moderately enlarged (52x40mm) & uniform parenchymal density, no abnormal tracer uptake.
Stomach wall is mildly thick (15 mm) & mild diffuse FDG uptake (SUVmax: 4.2).
Opacified small bowel and large bowel loops appear normal in caliber and fold pattern; no remarkable wall thickening or intraluminal mass lesion could be detected, no other abnormal FDG uptake throughout the intestine.
Seminal vesicles: appear normal. Genitalia: unremarkable.
Peritoneum & Mesentery: appears normal in pre and post contrast CT scan, no abnormally dilated mesenteric vasculature. No abnormal tracer concentration in the peritoneum.
No enlarged lymph nodes (with or without FDG avid) are noted at the region of porta hepatis, pancreatic, paraaortic, celio-mesenteric, parailiac, pelvic and inguinal regions.
Great Vessels: Aorta and IVC appears to be normal in diameter and clear lumen; no abnormal tracer uptake in its wall.
