Symptoms — what the patient reports (12)

Adult tapeworm infection is usually silent or causes only mild trouble
The typical picture is itching around the anus from escaping worm segments, plus mild belly pain [abdominal pain · itching]
Most people first realise when they notice worm segments passed in the stool
Rarely a segment is brought back up or inhaled
Other complaints are nausea, appetite change in either direction, weakness and weight loss [nausea · weight loss]
Less often headache, constipation, dizziness or diarrhoea [constipation · diarrhoea · dizziness · headache]
Children tend to have more symptoms than adults do
The fish tapeworm reaches 2 to 15 m yet still causes mild illness or none at all
One in five with the fish tapeworm get diarrhoea, belly pain, tiredness, constipation or pernicious anaemia [abdominal pain · anaemia · constipation · diarrhoea · fatigue]
Bloating, a sore tongue, sore gums and a change in appetite are also reported [abdominal distension]
Brain cysts can imitate almost any neurological illness [cyst]
Reported features are fits, focal weakness, raised pressure in the head, decline in thinking, headache and abnormal movements [headache · seizures]

Signs — what you find (8)

Worm segments may be seen in the stool or brought back up
Cysts survive only where the immune system cannot reach, chiefly the brain and the eye [cyst]
Cysts sit most often in muscle, under the skin, in the eye and in the brain, but only brain cysts carry real morbidity [cyst]
Where the brain cysts sit sets the picture: inside brain tissue means fits and headache, in the fluid spaces means hydrocephalus [cyst · headache · seizures]
Rare complications are blockage of bowel, bile duct or pancreatic duct needing surgery
The fish tapeworm can likewise obstruct the bowel or inflame the gallbladder
A heavy or long-standing fish tapeworm can cause megaloblastic anaemia, taking up to 80% of gut B12 [anaemia]
About 40% have a low B12 but only 2% become anaemic [anaemia]

Tests (12)

Diagnosis rests mainly on stool microscopy looking for eggs
Microscopy identifies the genus but frequently not the species
Molecular testing on stool or serum can name the species
Eosinophils are often up but only modestly, a rise of 1% to 15%, and IgE may be raised too
Beef and pork tapeworm eggs look identical; counting uterine branches on a passed segment separates them
Beef tapeworm segments crawl out on their own, so an anal swab may recover eggs better than stool
Egg shedding is intermittent, so microscopy misses a lot, with sensitivity from 3.9% to 52.5%
Stool antigen testing does not depend on eggs being shed and reaches 98% sensitivity against 38% for microscopy
Stool antigen can cross-react with roundworm, whipworm, dwarf tapeworm and protozoa
Brain cysts need molecular tests and imaging together
Imaging can stage how far a cyst has degenerated and how inflamed it is, and tracks response to treatment
A positive antibody does not prove live infection, since past exposure alone turns it positive

If not this — what else fits (10)

In an endemic area, belly pain, diarrhoea or constipation earns a stool microscopy
A negative stool does not clear tapeworm from the differential, because sensitivity is poor
Keep bacterial diarrhoea, viral illness and chronic inflammatory bowel disease in view
Suspicion rests on where the patient has travelled or been exposed
Parasite eggs of different species look alike and have been misidentified
Telling the two Taenia apart matters: pork tapeworm can seed the brain, beef tapeworm cannot
Multiple ring-enhancing brain lesions also arise from abscess, tuberculosis and syphilis
So do fungal infection, toxoplasmosis, hydatid disease, secondary cancer and CNS lymphoma
Multiple sclerosis and sarcoidosis round out the ring-enhancing lesion differential
Repeat testing or empirical treatment may be needed

Why

Formulary explicitly names Taenia saginata (beef tapeworm) and gives a single-dose adult regimen - the direct, guideline-backed first choice for this condition.

Cautions

Tablets should be chewed thoroughly and taken after a light meal.
If Taenia solium (pork tapeworm) is suspected rather than T. saginata, be alert for neurological symptoms suggesting neurocysticercosis, which needs urgent referral rather than routine treatment.
Refer urgently for signs of intestinal obstruction or unexplained weight loss.
Generally well tolerated; mild GI upset is the main side effect.
Patients may report the passage of visible worm segments.
